general characteristics

Catfish is a sea fish from the Perciformes. Mainly found in the north Atlantic Ocean, near Russia, Canada and even in the western Arctic. This cold-water fish feels comfortable in waters with temperatures below 5 degrees. Spends almost all of its time in ocean waters at depths from 400 to 1200 meters below sea level. It rises to the surface in search of food.

Catfish is a predatory fish. Its diet consists of smaller ocean inhabitants: sea ​​urchins, crabs, starfish. At depths, their food becomes jellyfish and smaller fish. The peculiarity of these fish is their knife-sharp teeth, thanks to which they retain a dominant role in the world's oceans. And it was thanks to these terrifying teeth that the fish got its name. And her middle name is sea wolf: like this animal, surprisingly developed jaw fish have fangs protruding forward and teeth turned inward.

Adult representatives can reach more than a meter in length and weigh more than a hundredweight. There are several types of catfish and they all differ in color. They can be dark gray to dark brown or even purple in color.

Blue. Found in the north Atlantic Ocean. Despite its name, its color can vary from dark gray to dark brown and even purplish-purple. The pulp of these representatives is jelly-like.

Striped. Adults reach 22 kilograms and exceed one and a half meters in length. Distributed in the waters of the White and Barents Seas, near England and Ireland. Prefers rocky bottom. The fillet is quite firm. It differs from other species by dark vertical stripes on the sides.

An adult catfish, so to speak, leads a sedentary lifestyle, moving along the bottom only in exceptional cases. But the young animals “plow” the ocean almost continuously.

During the spawning period, which for catfish occurs in the summer, females lay up to 30 thousand eggs. The rather large eggs of this fish settle on rocky bottom surfaces.

But these fish use their teeth mainly only to tear objects off the bottom. They can also split various shells with them.

They mainly use small inhabitants of the seas as food, such as jellyfish, crayfish, mollusks and other fish. When catfish change their teeth, they switch to softer food, but then return to the old food.

Reproduction

Based on research results, scientists have found that catfish are monogamous, breeding with only one partner throughout their lives. Fish reach sexual maturity at the age four years, although females take slightly longer to reach maturity than males.

During spawning, the female lays about 30 thousand eggs at a time, which are about 7 millimeters in size. The female lays larvae mainly on the bottom between stones. After spawning, both parents protect their future offspring.

Young catfish are born in early spring and at birth measure up to 20 millimeters in length. After birth, the larvae immediately swim as close to the surface as possible, where they look for food.
