In which seas are shrimp found? Shrimp fishing - what you need to know about the seafood delicacy

According to the classification, the Black Sea shrimp belongs to crustaceans that live in the basin of the Black, Azov and Mediterranean seas. It is not only food for fish and other inhabitants of water bodies. For many centuries in a row, this delicious delicacy has been preferred by gourmets and seafood lovers, so its production has acquired an industrial scale.

Shrimp (lat. Caridea) belong to arthropods from the order of decapods of the Crangonidae family. They can live safely in both fresh and sea ​​water, due to which they are widely distributed in all water bodies of the world. The depth of their habitat can reach up to 80 m, which they use to hide from enemies. They also know how to quickly burrow into muddy or sandy bottoms when encountering a predator.

Its body consists of 3 sections: cephalothorax, abdominal and caudal. Almost the entire body is covered with a shell consisting of chitin and other minerals. The tail plates are divided into segments; at the end of the body they form a tail fan, which helps to swim and move.

In the front part there are antennae, which are organs of touch and smell. Below them are located antennules intended for identification chemical composition water and food.

Crustaceans have 5 pairs of legs: the first 3 are designed for self-defense and capturing food, the next 5 are for movement. The remaining 2 legs are located under the abdomen and can be used both for swimming and for bearing eggs by females. In males, the first pair in the process of evolution turned into an organ for copulation.

The lifespan of shrimp is 3-5 years. The main diet consists of plankton and algae remains. Large crustaceans eat larvae and worms, small invertebrates and dead fish.

When females reach a size of 3-4 cm, they are ready to reproduce and can lay eggs. After a few days, small planktonic larvae hatch from the clutch. During maturation, they change their shell several times, with each subsequent one being slightly larger and stronger than the previous one. And only after going through 5 molts do they reach the post-larval stage and can switch to a benthic lifestyle.

Varieties

The Black Sea is home to several species of crustaceans, of which 2 belong to shrimp of the genus Palaemon, which are of commercial importance and are used as food.

These include:

• Black Sea grass (Palaemon adspersus);
• Black Sea rockfish (Palaemon elegans).

Palemon is slender or stone, which received its name from the required habitat. These creatures prefer to live among accumulations of stones in ridges, gorges and in shallow waters covered with dense thickets of algae. In secluded places, such inhabitants live peacefully, because... they are well protected from enemies. Here it is possible to find a lot of small plankton, which is their main food.

Rock shrimp can live and reproduce safely in any water salinity, so they are also found in the fresher Azov Sea. The size of an adult individual can reach 8 cm and weigh up to 8 g.

The grass palemon chose bottom areas overgrown with algae and sandy beaches near Anapa as its habitat. The color of the shell has light shades, the body is almost transparent, which allows it to live safely in the shallows. The size of such crustaceans is up to 7 cm.

Azov shrimp, living in the waters of the Kerch Gulf and the Sea of ​​Azov, are mainly herbaceous, preferring areas heavily overgrown with aquatic vegetation.

How to catch shrimp?

Crustaceans are valuable, nutritious and tasty seafood. They contain many vitamins, acids and minerals (calcium, magnesium, sodium, iron, iodine, etc.). The beneficial substances they contain help stabilize hormonal background in the human body and enhance its immunity. The disadvantage of shrimp meat is its high cholesterol content.

For your taste qualities they are prized among gourmets and fishing enthusiasts. Therefore, catching shrimp is carried out as in industrial scale and fishing enthusiasts. The latter prefer not only to eat them, but to sell them to local cafes and restaurants.

Shrimp fishing is most often carried out in evening time or at night. It is best to choose areas in the form of a backwater for this, because In places where the reservoir narrows, it is convenient to install trawls or traps. Caught crustaceans can be consumed not only for food, but also used as bait or as bait for fishing.

Many fishermen fish not only in coastal zone, but also from a boat. And the most ancient way Shrimp fishing was popular in Belgium and was carried out with the help of specially trained horses that pulled shrimp nets.

Habitats

To catch crustaceans in large quantities, you need to know exactly where the shrimp live. Their favorite areas are the bottom layers at a depth of 0.6 to 1.5 m, where there are accumulations of seaweed. If there are low tides and high tides in the selected location, then the exact time of their occurrence should be known, because Low tide hours are considered the most convenient for fishing.

Equipment and methods of fishing

Basic tools and methods of shrimp fishing:

1. A shrimp net (other names are landing net or drachka), consisting of a large-diameter metal circle (at least 70 cm) or a rectangle (aluminum, etc.), on which is attached a bag up to 3-4 m long made of fine mesh, and a long durable handles. A weight is attached to the bottom of the net, and sticks are attached to the sides, with which you can pull the net along the bottom when entering the water.
2. Trawls are made of 2 types (mid-depth and bottom), 4 ropes are tied to them, designed to be pulled so that the entire device stretches along the bottom of the reservoir behind a person. In this case, the fisherman stands waist-deep in water and drags the trawl against the current.
3. When fishing with a net or trawl, a flashlight is a bait to attract the attention of aquatic inhabitants, as well as additional illumination.

Homemade traps are widely used for catching Black Sea shrimp. To make a shrimp tank you will need the following materials:

• nylon mesh with cell 14 - piece 1.5x1.5 m;
• galvanized rigid wire - 3−4 m;
• thin wire braided in plastic - 0.6 m;
• 4 m of nylon thread (twine);
• float (plastic bottle, etc.) and rope.

First, a piece of mesh is taken and stitched into the shape of a large pipe. Another piece measuring 15x30 cm is similarly sewn along the length to enter the trap. A piece of thin wire is passed through it to create a ring-shaped entrance. The edges of the wire must be twisted and fixed.

Then the galvanized wire is threaded into the cells in the form of a spiral, which will hold the trap with rings. After 2-3 turns inside and 1 outside, its ends must be fixed at the first and last rings. Then you get a circle, then both edges of the large pipe need to be sewn to the wire rings using twine.

In the finale, between the middle rings, you should tie the bait with a rope. The float is also attached to the middle of the shrimp tank. Black Sea fishermen often use slightly rotten meat as bait.

The simplest shrimp trap is made from plastic bottle(float), a weight and a plant called a tumbleweed or broom. Several bushes need to be tied together, a sinker attached to the bottom, and a float on top. The trap should be lowered to a depth of 1 m overnight. Shrimps climb en masse on wet plants. In the morning, all that remains is to shake them out into a nearby bucket. However, this old-fashioned method is considered poaching and may be subject to a fine.

Natural enemies in nature

In conditions wildlife Most young shrimp die while still in the larval stage, because they are delicious and healthy food for many underwater inhabitants. They are eaten by bottom-dwelling fish species, seabirds and even some mammals. A very small number survive to adulthood.

Restrictions and bans on shrimp fishing

In accordance with the Order of the Ministry of Agriculture, a ban on shrimp fishing is annually imposed for the entire summer period. From June 1 to August 31, 1 person is allowed to catch no more than 5 kg of crustaceans. Fish protection officers carry out daily raids along the Crimean coast to prevent shrimp fishing.

However, from September 1, the season resumes. The condition of shrimp in the Azov and Black Seas, according to experts, is favorable. Their number is growing steadily, which is of interest to the official fishery and contributes to a rich catch.

Since 2016, fishing for these crustaceans has been carried out by mining organizations Krasnodar region and Crimea. The caught catch is supplied to restaurants and other food establishments. The domestic market for shrimp is in high demand due to its rapid reproduction. According to statistics, the annual shrimp catch in Cherny and Seas of Azov is more than 1.5 tons.

Sea delicacy – shrimp. One of the most valuable products that the sea gives us. They don't write odes about shrimp. They contain a lot of vitamins and useful substances, maintain normal hormonal levels, promote normal growth and development, increase immunity. They are used in nutrition and even in the treatment of cancer.

Where do they live?

Decapod crustaceans live in almost all the seas of the world, and some have mastered fresh waters for living. The size of some adult shrimp reaches three centimeters, but there are some that reach seven centimeters.

A large number of shrimp inhabit the shores of Japan, China, India, Southeast Asia. They are warm-blooded and cold-blooded, the first individuals are always large sizes and they are caught in the waters of Thailand, Brazil, and China. Cold-blooded shrimp are smaller in size and live in northern seas, it is believed that they are tastier than warm-blooded ones.

The most convenient place for breeding decapods is the Pacific Ocean, here they have all the conditions for life, which is why the islands of Somalia, Latin America, Brazil, and Ecuador are famous for their large and tasty shrimp.

There is deep-sea mining here and it is carried out on an industrial scale. Here, the prey is immediately heat-treated and frozen; it is believed that the quality of these marine animals is higher.

Belgium is famous for its old method of catching crustaceans. They attract tourists with nets, baskets and horses.

And in Russia, shrimp can be caught in the Far East; here the shores delight with almost a hundred species of shrimp. Two species live in the Black Sea, one lives on sandy soil, on the bottom, where there are small pebbles, the second on rocky areas, near rocky shores.

Shrimp caught in the Sea of ​​Azov is considered one of the most delicious. The Baltic Sea, the North Sea, the waters of Transcaucasia and even the Amur River are rich in this pure protein, which is small in size, but tasty.

It is necessary to catch shrimp at night or in the evening; you can set traps in advance so that the “harvest” can be collected in the morning. The habitat of these crustaceans is at a depth of six hundred centimeters to one and a half meters, where there is a large accumulation of algae so that it can hide from danger.

Be sure to have information about the ebb and flow of your reservoir. The most convenient time fishing - low tide, hours - evening or night.

“Handy” means for catching shrimp

You can catch shrimp in different ways. The most commonly used is a trawl or.

A metal semicircle, or possibly a rectangle, most often made of aluminum, to which a 3- or 4-meter bag with small cells, like a fishing net, is attached, is called a trawl.

There are two types of trawls - mid-water and bottom. There are 4 long ropes attached to the trawl, which you need to pull so that this device moves behind you along the bottom of the reservoir.

The net must have a long, strong handle and a bag with very fine mesh; if the cells are not small, the shrimp will simply slip out of the net. The net must be of a sufficiently large diameter.

You can also make a shrimp trap. To do this, you should take a small mesh and sew it in the shape of a pipe, pass a piece of galvanized wire inside the nylon pipe. Since it is in a spiral shape, it will keep the rings trapped.

Two or three turns inside and one outside will be enough. The first and last rings are fixed, and an even circle is obtained. Now you can sew the small pipe to the other edge of the wide pipe, and the edges of the wide pipe need to be attached to the outer rings.

To catch this delicacy, you also need a flashlight, because any small mollusk strives for light in the dark.

How to increase your fish catch?

Over 7 years of active fishing, I have found dozens of ways to improve the bite. Here are the most effective ones:

1. Bite activator. This pheromone additive attracts fish most strongly in cold and warm water. Discussion of the bite activator “Hungry Fish”.
2. Promotion gear sensitivity. Read the appropriate manuals for your specific type of gear.
3. Lures based pheromones.

Clam fishing rules

Ostdenkerk - a place where they catch shrimp on horseback

Shrimp are caught with a trawl either in the coastal zone or on a deserted coast, in places where there is a lot of algae. They pull the trawl against the current, while being waist-deep in the reservoir. When the current changes, the trawl is moved so that it again stands against the current. In this way you can short term catch a lot of shrimp.

It’s easier with a net; you need to enter the water, go around all the stones and move the net around them. You can catch shrimp this way, but not very many. But if you walk along the shore with the same net in the evening or at night, and even with a flashlight, the result will please the night hunter.

And homemade traps are tied together and thrown into the pond.

An interesting way of fishing among Black Sea fishermen.

They catch shrimp in two ways:

1. One, “as old as time” with a sealed flashlight that runs on LEDs.
2. Another original one is that in the morning, near the high rocky shores, from a boat they release a net with small meshes with a piece of missing meat. Literally half an hour later they had a wonderful catch.

Reminder on catching decapod crustaceans

You can catch shellfish from any place convenient for you - from a boat, from a pier, from the shore, the main condition is that the radius of your net is equal to the depth of the place where you are fishing. Give the net time to sink to the bottom and begin to pull it out with a rope.

When you pull the net, the rope will tighten, taking the shrimp with it. Pull it out and keep in mind that in addition to shrimp, you will also find some seafood in the form of dirt, sand and silt.

In the absence of a trawl, net or mesh, you can use basic gauze, which is sold at the pharmacy. Fold it in several layers, tie some weight to two ends, and lower it to the bottom, near the shore. Walk parallel to the shore and pull your new “net” along with you for several tens of meters. Then take it out and enjoy your catch.

Season for catching decapods

But you cannot hunt shrimp all year round; fishing for them is prohibited during the spawning season. This period is from June 1 to August 31.

In some places it is prohibited to catch shrimp with a trawl, but you can use a trap. Sakhalin fishermen could catch shrimp in the summer without restrictions.

It is forbidden to catch shellfish in the Black Sea, or rather, one person can catch no more than five kilograms. The government also banned shrimp fishing on the Crimean Peninsula. Employees of the East Black Sea Guard carried out daily raids along the coastline.

In the Sea of ​​Azov, until the beginning of August, it was possible to receive fines for catching shrimp. In the Sea of ​​Azov, one person, when catching crustaceans, is allowed to use a net with a diameter of no more than seventy centimeters and you can catch no more than one kilogram.

Shrimp - a hobby, a delicacy and a harm

Whether you're an amateur or a professional, shellfish fishing is an unforgettable experience. Beautiful weather, warm water, sun and your favorite hobby, what could be better?

And if you also keep in mind what can be built from these living creatures, what dishes to prepare and what benefits they bring to the body. There is an opportunity to strengthen cardiovascular system, normalize the central nervous system, reduce blood clotting. A person will receive the daily requirement of iodine by eating only fifty grams of shrimp.

But people with high cholesterol in the blood, you should avoid this delicacy, since they themselves contain cholesterol, heavy metal salts, and toxic substances.

Shrimp: a way of life

Freshwater shrimp, where they live, are an important element of the fauna of reservoirs, an essential link in food chain. Many fish and waterfowl feed on them. Freshwater shrimp are also of significant economic importance.

By the end of the 20th century. The freshwater shrimp Exopalaemon modestus was discovered in the Kapchagay reservoir in Kazakhstan, and in Uzbekistan, in the Chirchik and Syrdarya rivers, in the Arnasay lakes, the Chinese shrimp Macrobrachium nipponense has taken root. It was accidentally introduced into fish ponds along with juvenile Far Eastern fish from China. The same shrimp accidentally ended up in artificial cooling ponds at hydroelectric power stations in the Moscow region, then at the Ryazan State District Power Plant, and began to reproduce beautifully there in the constantly warm water. They were already specially settled in the cooling lakes of state district power plants in Belarus and Moldova. In such reservoirs, shrimp eat lower algae, which develop en masse in warm water, and themselves serve as food for many fish. In particular, they are readily eaten by pike perch. Currently, experiments are being conducted on breeding the giant eastern Rosenberg shrimp for food purposes in the Volga delta and in warm-water basins in the Crimea.

As observations in Belarus have shown, in the cooling ponds of state regional power plants, the number of shrimp can increase by 8.7 times or more over the course of a year. In Moldova, two years after their settlement, their number increased from 2 thousand to 600 thousand.

Freshwater shrimp are a fairly valuable food product, which is of significant importance in the tropics and subtropics. They are grown in ponds and rice paddies in two dozen countries around the world. In constantly warm water, shrimp can reproduce year-round and reach large numbers: up to 50 crustaceans per 1 m3 of water. In the USA, India, Australia, and Israel, the number of shrimp in ponds can grow 60 times per season. Mainly 10–16 species of the genus Macrobrachium are grown, some representatives of which reach a length of 30 cm and weigh 150–250 g (for example, the already mentioned giant eastern Rosenberg shrimp, Macrobrachium rosenbergii).

You can learn a lot of interesting things about shrimp by observing them in an aquarium. These creatures get along well in captivity and over the last decade have become quite widespread among aquarists. They clean aquarium plants from fouling by lower algae, act as orderlies, complement the diversity of the population of an indoor reservoir, usually limited only to fish, and decorate the underwater landscape with their original appearance. The aquariums contain Japanese marsh shrimp (Caridina japonica), South Asian bee shrimp (Caridina serrata) and bumblebee shrimp from the genus Neocaridina, Far Eastern freshwater shrimp. Small shrimp, for example, caridina bee, live in captivity for 1–1.5 years, large ones for 2–4 years.

A volume of 7–10 liters per individual is sufficient for shrimp; they prefer a sandy bottom, clean water, and feed on detritus, leftover fish food, and microalgae. Large shrimp can sometimes attack sick or, less commonly, fish sleeping on the bottom at night. They usually do not touch healthy active fish. Attacks on fish and cannibalism are more often observed in stressful situations for shrimp - after transplantation, with a lack of regular food, overcrowding, sudden changes in living conditions, in particular, significant temperature changes within 1-2 hours.

According to some information, shrimp of the genus Caridina require brackish water for the development of eggs and larvae, and Neocaridina bumblebees also reproduce in fresh water. But the biological features of many species of shrimp have not yet been sufficiently studied, so it is interesting to recommend that schoolchildren keep them, along with fish, in aquariums and observe them. Topics to observe may include the following.

1. Variability of color: lightening and darkening depending on the intensity of lighting, time of day, color of the soil different types. Effect of nutrition on color. Thus, when eating red mosquito larvae (bloodworms), the body of shrimp can turn pink, when eating dark tubifex worms, it can darken, and when feeding on green algae, it can turn green.

2. Observations of the movements and orientation of shrimp are instructive. Walking legs on the cephalothorax help them walk on the ground and climb vertically on plants. Here they are also held with the help of abdominal swimming legs, which in other cases help the shrimp to swim both forward - horizontally, and up and down - vertically. The movements of the caudal peduncles - uropods and the bending of the end of the abdomen help the shrimp not only quickly jump back a considerable distance, but also drive away other shrimp and fish. Also, the molting shrimp, whose legs have not yet hardened, moves with sharp flexions and extensions of the abdomen and pushes.

When searching for food, the shrimp primarily uses its antennae, claws, and jaws, all the while feeling the substrate around it. Its eyes distinguish only relatively large, closely located objects and are used when viewing the surrounding space when swimming and moving and when monitoring the approach of danger. This can be noticed when catching shrimp with a net.

3. Observations of the behavior of shrimp are of interest. Large macrobrachiums and palemons exhibit elements of territoriality, often stay in one corner of the aquarium, and try not to let other shrimp and fish in there. But we did not observe any fights among the shrimps - they, putting their open claws forward, quickly spread to the sides when they meet. Males vying for a female behave in a similar way. Males guard females during molting and mating.

4. Experiments on feeding shrimp, their choice of food items, the effect of temperature on the growth and development of shrimp, and the frequency of molting are worthy of attention. The shrimp quickly begin to recognize the place where food constantly appears, and try to stay nearby all the time. This is how they form conditioned reflex to the place and time of feeding. This indicates a certain development and complexity of the nervous system of shrimp: they have more plastic behavior than arachnids and a number of insects that almost do not form conditioned reflexes.

It is worth paying attention to the structure of the discarded shells - exuviae. When shrimp molt, damaged or previously lost limbs grow back and the process of their regeneration occurs. This is especially noticeable in young ones, as they shed more often.

5. Reproduction of shrimp is a special area of ​​observation. The peculiarities of the female's care for the eggs and the change in their color as they mature are interesting. Females can regularly lay unfertilized eggs, which they then gradually lose. You can trace the influence of temperature and salinity of water on the development of eggs. Finally, the complex development process of shrimp larvae is very interesting. If you manage to grow ten young shrimp from larvae in an aquarium, this is already a great success. You can feed the larvae with particles of powdered milk, yeast, boiled milk sprayed in water. egg yolk, ground grain...

Many aquarists prefer to keep not only fish, but also other aquatic inhabitants in an aquarium. For example, now it’s fashionable to start aquarium shrimp. They are not very capricious in their maintenance, and it is very pleasant to watch them. After all, aquarium arthropods are very different from their marine counterparts. Aquarium shrimp can be colorful and active. But the owner of an indoor pond needs to know the peculiarities of maintenance and breeding.

Description of aquarium shrimp

The aquarium shrimp is an omnivorous crustacean with high level endurance. In their natural environment, shrimp live in almost all bodies of water (freshwater and saltwater). The homeland of various shrimp is the warm waters of Panama, Japan, Venezuela, etc. As a rule, most individuals come from Asia.

Most aquarium shrimp come from Asian waters.

Small crustaceans have a small body consisting of several segments. Each of them has a pair of limbs. In total, shrimp have 5 pairs of legs, which allow them to get food and move quickly. Aquarium shrimp also have a massive tail. It allows you to make jerky movements, for example, in case of danger. The first 3 body segments are covered with a shell and fused to the head. This allows shrimp to survive even in the company of predators.

The mouthparts of shrimps have a complex shape. It consists of 3 jaws and jaws (the first 3 pairs of limbs). The jaws help the other limbs move and grasp and hold food. Despite the fact that the aquarium shrimp is not large in size (up to 8 cm), they have an excellent sense of smell and touch. Long antennae-like antennae capture the smells and rustles of future food. Shrimp also have rotating eyes. This allows you to quickly detect food and hide from the enemy.

Female shrimp have abdominal pleopods (abdominal legs), which are needed for swimming and bearing eggs. And in males, the first pair of these legs has degenerated into a reproductive organ.

Thanks to their complexly organized body, shrimp are distinguished by their endurance.

Varieties

There are many varieties of shrimp, but Russian aquarists have fallen in love with just over a dozen species. It is important to decide on the choice of shrimp before purchasing them. Indeed, despite their unpretentiousness and survival rate, representatives of different species require special maintenance. So you can buy small shrimp for a small aquarium, but then they will become too large and the aquarium will have to be changed.

The most popular representatives:

1. Red crystal. White shrimp with red wide stripes. It is whimsical in its maintenance (the water temperature should be 26 degrees), but it eats little. Possesses poor health due to intraspecific crossing.
2. Red cherry shrimp is the most popular type of shrimp with a bright red body. Unpretentious in maintenance, easy to reproduce, can live in large groups(males are much smaller than females - 2 and 4.5 cm, respectively).
3. Amano are light green shrimp with brown spots on the sides. Kills all harmful algae and other vegetation. They are capricious in their keeping, but very peaceful.
4. Tiger shrimp grow up to 4 cm. Outwardly, they are brighter than their tiger relatives, which we see in stores. They are inexpensive, but require a large aquarium (at least 50 liters).
5. The yellow shrimp is unpretentious in keeping, but you need to monitor the cleanliness of the water. They reproduce easily (up to 30 children at a time).
6. Blue Dream is a small bright shrimp (up to 3 cm). When properly maintained, they rarely get sick and reproduce easily. Life expectancy is up to 3 years.
7. Black neocardina (black diamond) is a beautiful shrimp in several shades of black. It is very rare, although inexpensive.
8. Transparent shrimp (other names: glass, ghost, Indian). They live only 1.5 years, but grow up to 4 cm. They help keep the aquarium clean, but survive only in the company of small fish.

Photo gallery: aquarium shrimp of different types

Amano shrimp have an almost transparent body with small brown dots, but nevertheless, these shrimp are very fond of aquarists Several types of shrimp different colors will decorate any aquarium Green shrimp looks very beautiful only on a contrasting background (merges with algae) The most colorful aquarium shrimp are red (red cherry and red cardinal) The Red Crystal is a brightly colored shrimp that is recommended for inexperienced aquarists. At a young age, the glass shrimp is practically invisible in the water. A rare species of shrimp for Russia - blue tiger Tiger prawns can have very brightly colored heads and tails. Black shrimp are descended from blue shrimp; they are often rejected by color, so it is difficult to find them in a pet store

If you are confused and don't know which type of shrimp you like best, consult a pet store salesperson. A knowledgeable specialist will tell you the features of the varieties that are commercially available. Many aquarium owners choose fish and shrimp based on price and appearance. Tell the seller what size your aquarium is, what fish already live there, look at the neighbors of the shrimp in the pet store.

When I bought different animals for my aquarium, I first took 1-2 individuals, quarantined them, and then transplanted them into the main aquarium and observed. If for several days the fish, shrimp, etc. behaved actively and vigorously, I went to the store and bought the required number of individuals. If you are not sure of the seller’s competence, you can check the information yourself. By the way, some fans aquatic fauna they buy rare inhabitants of the aquarium on the first day of delivery (not yet disassembled). However, it is best to wait a few days, because shrimp are brought from Asia, you never know - maybe they are sick.

Pros and cons

Every aquarist dreams of seeing in crystal clean water bright inhabitants of the aquarium. Some create special lighting to highlight the beauty and brightness of the shrimp. This is a big plus of these crustaceans. Their choice is so wide that you can choose small shrimp to match the small beautiful fish or large, “meaningful” individuals so that they do not get lost among the beautiful fish. Moreover, their prices are rarely high (beautiful, bright crustaceans can be bought even for 50–100 rubles).

Another plus is ease of maintenance. Some types of shrimp (for example, red cherry) seem to require no care at all; they can adapt to any conditions. In addition, you don’t have to worry about the size of the tabletop reservoir. Shrimp can be stocked either in a nano aquarium (up to 1 liter) or in a very large container (up to 400–500 liters). True, the size of the individuals and the population size will depend on the size of the container. But such small creatures will help the owner keep the aquarium clean. Shrimp like to swarm at the bottom, among the leaves of plants and the surfaces of stones, so the water will not become cloudy due to uneaten food and plaque.

The disadvantage of a bright cleaner is that it can become a victim of aggressive fish. Some shrimp (such as the red cardinal) only grow to 1.5–2 cm, so a relatively large fish may mistake this creature for food. Young shrimp are especially at risk of being eaten. After all, the thin shell of crustaceans cannot protect against the teeth of predator fish. If you take good care of the shrimp, they will begin to actively reproduce. Some owners of arthropod pets have to “clean” shrimp rows. Experienced shrimp connoisseurs select those that are lighter (paler) and hand them over to a pet store or distribute them to friends. Bright and beautiful individuals will remain in a spacious aquarium.

The main advantage of aquarium shrimp is color variety

As mentioned above, shrimp are not particularly picky about the volume of their reservoir. However, the activity of the fish and their reproduction depend on the capacity of the aquarium. Some aquarists calculate the permissible number of shrimp as follows: 1 shrimp needs 1 liter of water. But it is also important to take into account the size of the tank’s inhabitants. For example, macrobrachiums grow up to 8 cm, which means they need more water (up to 4 liters per individual).

The water temperature can fluctuate from 20 to 30 degrees. This mode is suitable for all shrimp. But you need to remember that at temperatures below 18 degrees the shrimp becomes inactive (almost asleep). Conversely, the warmer the water, the more active and cheerful the shrimp becomes. Aquarium pets do not tolerate sudden temperature changes. Even if you transfer the aquarium to a different seasonal mode, you need to lower/raise the temperature gradually. A special heating device may be useful for this. And filters and aerators may also be needed (but this is not necessary).

Once a week you can change part of the water (at least 1/3). If it is not possible to purchase or deliver special purified water, you can filter ordinary tap water. My father poured plain water from the tap into an aquarium with snails, and after a couple of days I poured this water into a container with fish. It was important that both aquariums were in the same room (so the water temperature became ideal).

The activity of shrimp depends on the water temperature in the aquarium.

The aquarium in which the shrimp will live needs to be planted with a large number of different plants. Usually hornwort, Java moss, pistia, cladafora, etc. are planted in such containers. Brightly colored pets will eat particles of leaves, and it is also easier to hide in thick grass in case of danger. Plants may require light for better growth, although shrimp do not need it as such.

Water parameters need to be checked periodically. It should be hard, since shrimp can molt, and instead of the shed shell, they will need to grow a new one (minerals for this are usually taken from hard water). However, the water should not contain chlorine (shrimps cannot tolerate it). You also need to minimize the amount of copper. This metal can cause the death of your beauties. Moreover, both adult shrimp and their larvae can die.

You also need to comply simple rules about environmental conditions. The room in which the aquarium is located should not be too noisy. There should be no vibrating equipment near the aquarium (such as washing machine or microwave). It is unacceptable to use air fresheners, insecticide aerosols and other harmful sprays near the container. Any poisons can get into the water and poison small crustaceans.

The more plants you plant in your shrimp aquarium, the better.

What to feed

Shrimp eat whatever is offered to them. This could be food left over from the fish (bloodworms, daphnia, cyclops, etc.) or special food for shrimp, which is sold in any pet store. And if after the fish there is nothing left for them, then the cleaners will eat particles of algae (there are a lot of them in the soil and on the surfaces of the leaves).

If there are no fish in an aquarium with shrimp, then you will have to buy food specially designed for crustaceans. Although many shrimp aquarium owners buy food intended for fish. However, it is important to understand that special food is healthier, because it contains all the minerals needed for shrimp. I bought my shrimp special food in the form of flakes. It is believed that such food contains vitamins that are beneficial for the color and quality of the shell.

You can also feed shrimp with vegetables (cucumber, spinach, etc.). Some people give shrimp garlic, and there are even aquarium owners who feed shrimp pasta, but this is not very good, since flour in the aquarium can cloud the water and turn sour. It is important not to overfeed your aquatic pets, from large quantity If there is no available food, the shrimp will become lazy and will not clean the aquarium. The recommended feeding frequency is 2–3 times a week. These beauties will definitely not go hungry.

Shrimp diseases

The body of the souvoika is a “bell” on a long leg

Another risk is fungal disease. A shrimp can “pick up” the fungus even in an aquarium with relatively clean water. The fact is that the fungus can remain in aquarium water for a very long time without showing itself in any way. At small change water parameters (for example, a decrease in temperature), the fungus becomes more active, and a whitish coating may appear on the shrimp’s body. The emerging disease sucks out of the sick individual nutrients and poisons the body with toxins. Crustacean larvae die almost immediately, and in this case it makes no sense to treat adult shrimp.

If the larvae turn white and die, the aquarium should be cleared of corpses, healthy inhabitants should be removed, and then the container should be treated with a 0.1% solution of bleach (or bleach). Treflan can be used for treatment. It is buried in a hatchery with infected shrimp at a concentration of 0.00002%. After 24 hours, the water must be replaced by 1/3. However, such treatment is ineffective, so it can rather be called prevention.

Shrimp can only be treated in a fish tank, and baths with salt are best done in a separate container (for example, a bowl)

Shrimp can also get sick. infectious diseases. Often shrimp become infected with ichthyophthyriasis. It is easy to recognize such a disease - by the white specks on the body of aquatic pets. This disease is caused by protozoa (ichthyophthorus), all inhabitants of the aquarium can suffer from it, but it can be treated. The popular name for ichthyophthyriosis is semolina. To treat shrimp you need to do the following:

• increase the water temperature in the aquarium by 2–4 degrees, increase aeration;
• if the disease is detected at the initial stage (1-2 points), then Tripaflavin will help (it is important to follow the instructions on the package);
• in advanced cases, you need to use stronger drugs: Tetra Contralk, Kostapur, etc.;
• in emergency cases, you can use Furazolidone (1 tablet of 50 mg per 15 liters of water), but this drug destroys the microflora.

Shrimp are also susceptible to various types of viruses, the effect of which has not been fully studied. Therefore, a treatment has not yet been found. If your shrimp gets sick and you couldn’t identify the soreness, urgently remove it, change the water in the main aquarium, and then go to the veterinarian or pet store. Here you can’t do without expert advice.

Fish compatibility

In order for shrimp to please the owner with their bright appearance and active behavior, they need to choose the right neighbors

Peace-loving shrimp behave very modestly even in a large aquarium. This is due to the fact that the crustacean animal is afraid of being eaten. Therefore, you need to choose equally peaceful neighbors for the colorful inhabitants of the aquarium. Fish and other small creatures will be ideal neighbors for shrimp:

• neons, guppies or zebrafish;
• micropetilia, barbus gracilis and paratocinclus are relatively good neighbors;
• snails (ampularia, helena);
• micro-assessments;
• Siamese algae eaters;
• Ancitrus, Ottoncinclus, sticky catfish (these catfish simply ignore shrimp);
• swordtails, rhodostomuses, corydoras, etc. - only under the right conditions.

Small fish (guppies, zebrafish, neons, etc.) will not attack shrimp, but more active individuals may act out. For example, swordtails or corydoras may attack a shrimp if the aquarium is too small, and the pets have to fight for territory. In addition, the owner needs to avoid provocations in the form of joint feeding. It is better to sprinkle food for shrimp in the corner of the aquarium where the most plants are located (let the food fall into the thick of the algae). The shrimp will get food, but the fish will not get there.

Guppies get along in any aquarium and with any neighbors The most popular and accessible type of zebrafish is the rerio. Microrasboras will get along well with shrimp and any other living creatures. Neon is a small glowing fish with a minstrel character. Siamese cannot boast of a bright appearance, but they are the same cleaners as shrimp.

When I had a shrimp in my aquarium, its only neighbors were small, colorful guppies. The shrimp was constantly busy with some crumbs at the bottom, and the guppies swam about their business, noticing only each other. One shrimp can't reproduce, so I didn't bother it. But if there are several shrimp, they need to be removed during spawning, otherwise the guppies may swallow the little ones out of fear. However, this feature is characteristic of all viviparous fish.

Undesirable neighbors for aquarium crustaceans:

• cichlids, loaches;
• barbs;
• angelfish;
• goldfish;
• gourami;
• aggressive species of catfish, etc.

In addition, you need to take into account the varieties of shrimp. Sometimes a small, harmless fish becomes a more useful neighbor than another shrimp. For example, blue shrimp cannot be kept in the same aquarium with other small crustaceans. The fact is that the bright color of a pet can “go away” if it is uncontrolledly crossed with a paler shrimp. But if the aquarium owner manages to cull the pale arthropods in time, then there is nothing to fear.

Breeding

It is quite possible to breed shrimp without any special skills.

Breeding shrimp is not difficult. The main condition is that there must be individuals of both sexes. Many aquarists simply observe the breeding process without helping their pets in any way. For successful selection of crustaceans, you will need a separate aquarium, where you will need to place the pregnant shrimp.

How to distinguish a female from a male

Sex differences can only be found in adults. To understand where the male is and where the female is, you need to pay attention to 4 signs:

1. Body dimensions.
2. Color of individuals.
3. Behavior.
4. The presence of a “saddle”.

Male shrimp are always smaller than females. For example, cherry shrimp can grow up to 1.5 cm, and their males - up to 1–1.3 cm. Even if your humble cleaners have not grown to a record size (within their species), it is still possible to distinguish boys from girls. Females are both larger and brighter. Most boys are painted in paler colors, sometimes the body of the male is almost colorless.

Two large shrimps on the right and 1 in the center are females, and small and almost transparent ones are males

If shrimp of different ages live in the same aquarium, then the sizes will not say anything. Then you can pay attention to the behavior of individuals. Small but nimble males always try to create “violent activity.” They are always interested in everything and need to dig deeper into everything. But the females are calmer, they slowly move around their possessions, only occasionally taking part in some common affairs.

The surest sign of the difference between females is the presence of a so-called “saddle”. This is a white formation on the back of the animal (in the place where the abdomen meets the chest). It is usually visible through the shell. The saddle is the ovaries. It is here that the eggs mature, which is why males do not have such a saddle.

Shrimp breeding

Females carry eggs under the shell, thus forming a “saddle”. After fertilization, the eggs move under the tail, where they develop for another 3–4 weeks. At this time, the female looks after the eggs and removes them, constantly shaking them. Closer to birth (about a month after fertilization), eyes appear in the eggs. They can be seen directly in the belly of a pregnant female. The shrimp will give birth to 15–30 fry. They will be a smaller copy of their manufacturer (about 2 mm). Newborn shrimp are not visible at first (3–4 days) because they are small, transparent and move along the walls and leaves.

Shrimp fry are born already recognizable: they have eyes, antennae and a tail.

Small shrimp are good at hiding. Neons won't eat them. Danios can catch a little, but they also won’t catch everyone.

How long do aquarium shrimp grow and live?

All shrimp grow differently depending on the variety. It may take from 3 months to 1 year for the fry to grow into a beautiful, bright shrimp. However, many shrimp continue to grow even when they become adults. To fit into its dense shell, the beautiful creature needs to periodically change its chitinous shell. Shedding occurs approximately once a month. This is a very interesting process; before shedding the old shell, the shrimp itches on the stones. Even those individuals that have already grown to their maximum size shed. This is necessary for several reasons:

The average lifespan of shrimp is from 2.5 to 6 years. But the point is not only how long an individual of a particular species should live. Water temperature also affects lifespan. For example, when high temperature(above 26 degrees) animals age faster (such individuals do not live more than 3 years). Those who live in cold water(15 degrees and below). Females live longer than males.

The aquarium shrimp is a small arthropod crustacean. Such shrimps can decorate any aquarium, because they are bright and spectacular, and they are easy to care for. The main thing is to maintain water parameters and provide the shrimp with good neighbors with non-aggressive fish.

A shrimp is a crustacean animal. On at the moment this is a sought-after product. Industrial fishing allows many companies that engage in this work to generate income. The demand for the product is due to its excellent digestibility and the presence of many vitamins and microelements. And thanks to developed technologies and infrastructure, the buyer receives the goods high quality. Read more about catching shrimp in the article.

Benefit

Animal meat contains a lot of protein, which is easily digestible and contains many essential amino acids. The latter cannot be produced in the body; they come only with food. This product contains much more iodine than beef, so it is in demand in regions with iodine deficiency.

A rich set of mineral elements and vitamins affects almost all organs and systems, including skin, hair, and nails. This is an indispensable remedy for the prevention of heart and vascular diseases.

Habitats

Where do they catch shrimp? There are several habitats of these creatures:

1. There is a tiger species in the Pacific Ocean. Closer to the equator, animals are larger and tastier. A wide variety of species are found in warm waters. There are fewer of them closer to the poles.
2. These animals are found in Kenya, Brazil, Ecuador, and Somalia. In these countries, the water usually has a temperature of +25 to +30 degrees, which is favorable for the development of these inhabitants. Their dimensions can be 30 cm. On the territory South America takes place on farms, resulting in a high-quality product.
3. A temperature drop to +15 degrees causes death sea ​​creatures. Warm water works in a similar way - +35.
4. In the Barents, Baltic, and North Seas small animals, 2.5-10 cm, live. Animals caught off the coast of Canada and Greenland are of great value.
5. There are many marine inhabitants in the Mediterranean, Black, and Azov Seas.
6. Freshwater animals are found in the Amur and cave reservoirs of Transcaucasia.
7. There are crustaceans in fresh waters Far East. The population is a relict because it has lost contact with the rest similar types due to geological changes in the land. They live at +15 degrees, but when the temperature drops to 10 degrees, the larvae die. Adults cannot tolerate drops to 0 degrees.

If animals live at temperatures that differ from optimal temperatures, they grow more slowly and also stop reproducing. In this climate they exist for up to 3 months. Shrimp are not very sensitive to salt water, since even those that live in fresh water are of marine origin.

Industrial types

Although several thousand crustaceans live in nature, there is no commercial interest in all of them. In Russia, the most popular shrimp is the cold-water red beer shrimp. It is small in size and sweet in taste. It has subspecies - red comb and northern chilim. Game and king prawns are in demand.

The southern pink shrimp lives off the coast of Africa. Captain's is found in artificial reservoirs in China and Korea. In the Black and Mediterranean Seas there is sand shrimp, which is fished by Germany. Grassy fish is caught black sea shrimp. US restaurants serve spotted deep-sea creatures, as well as white and pink ones. There is a Chilean species, common on the coast of Chile.

Where and when to fish?

When can you catch shrimp? To get a rich catch, you need to go for shrimp at night or in the evening. Many people recommend going fishing early in the morning, but this should be before dawn. The location must be chosen according to the type of inlet or where there is an intense narrowing of the channel. The catch can be on the channel that connects the sea and the estuary.

The inhabitants crowd around the walls and supports of the pier, concrete structures, breakwaters, rocks, and the side of the ship. There are also a lot of them in algae thickets. A bright flashlight can serve as bait. IN dark period They illuminate the water column. Lanterns with sealed housings are sold specifically for this purpose. These products are suitable for use underwater. The crustaceans quickly come running towards the light. How to catch shrimp? Several proven methods are used for this.

If you choose trawl fishing, you will need chicken giblets, fish, and meat. Fishermen have different opinions on this issue. Some believe that the bait should be somewhat dull, while others say that it is necessary to use fresh bait. Another subtlety is considered to be low tides. If you know about the time of their onset, you will be able to improve your fishing results. How to catch shrimp in Primorye? All proven methods are used for this. Let's look at them in detail.

Net

How to catch shrimp? By law, it is allowed to use a net with a diameter of up to 70 cm. You need to choose a device with a long and strong handle. While illuminating the lantern, it is held near walls, supports, structures, near seaweed and a ship.

In this way, the catch will not be large, but if the goods are not for sale, it will be enough. Along with the shrimp, silt, algae, and sand penetrate into the net. If you have a boat, you can fish from it. All the rules are the same, you just need to take a suitable net. How to catch shrimp in Any of the methods indicated in the article is suitable.

Trawling

Another way to catch shrimp? A trawl is a device for catching not only crustacean inhabitants, but also fish. It is a metal circle or oval to which a fine-mesh mesh, similar to a bag, is connected. Its length can be 4 meters.

After immersion in the water, the trawl must be pulled along the bottom overgrown with algae. To do this, ropes are fixed to the metal frame. Often the trawl is tied to a boat. It is possible to install it in a place where shrimp live, but you need to place bait there in advance. Placing the device in the area of ​​narrow ducts helps. Then you just need to control the flow and turn it around in a timely manner.

Net

It is usually used for fishing from a boat. How to catch shrimp with a net? It is lowered to the bottom with sinkers and pulled out using a special rope. When choosing a fishing location, it should be taken into account that the depth should not be higher than the radius of the net.

There are other methods of catching crustaceans. For example, you need to tie the reeds into a medium-sized bundle, place them inside the bait and sink them to the bottom. After some time, you need to pull out the trap with its contents. But this option is poaching, so there is a possibility of trouble with it. How to catch Azov shrimp? Hunting for marine life is carried out in any of the 3 ways indicated here.

Do we need to take seasons into account?

It is important to consider not only how to catch shrimp at sea, but also the fishing periods:

1. Summer is spawning time for animals. Fishing during this period is prohibited, and poaching is punishable by law.
2. The mass run usually occurs in spring and autumn when the water is warm. Therefore, hunting for marine life in May, September, and October will bring great results.
3. In winter, crustaceans migrate to a depth of up to 30 meters, so even if you use a net or not, it will not be effective.

Deep sea fishing method

The deep fishing method is considered a complex process that can be used in the industrial field. The caught crustaceans are subjected to heat treatment on the ship, which improves their quality. Typically, large trawls are used for industrial fishing. They are launched along the bottom, which allows them to collect everything in their path.

This method allows you to catch shrimp, fish, shellfish and other inhabitants. The trawl is capable of plowing the seabed, destroying everything around it. It is lifted onto the deck by winches. When the production is sorted, the products are frozen and delivered to the mainland.

Shrimp Preservation

Since these marine creatures spoil quickly (in about 2-3 hours), it is necessary to properly preserve them after catching. Recreational fishermen place shrimp in a container with ice. If fishing is industrial, then seafood is frozen on the ship. You can preserve the product this way: place it in a cut-off bottle, fill it with water, and then put it in the freezer.

Thus, shrimp fishing has its own characteristics. You need to know where, when and how this can be done. You also need to remember about the safety of the product. In this case, hunting for sea creatures will bring excellent results.
