• What kind of fish are there?

    There are a great many kinds of fish, but everything is simplified if we divide them into two main classes: sea and river. We have put this simple division into the basis of our article. You will learn what kind of fish there are sea and river (freshwater). But before that, a few words about why fish are divided in this way. It's all about the water in which certain types of fish can live. Of course, there are families of fish, such as perch, cod, salmon, etc., but, as you know, sea water is salty, and river water and water in lakes are fresh: therefore this classification of fish is quite justified. Now let us dwell on some species of river fish that are most common in our waters.

    What are river fish

    Among river fish, the most popular species are such as ide, ruff, trout, crucian carp, bream, sturgeon, burbot, tench, bleak, perch, pike, roach, carp, pike perch, catfish, sterlet, eel, chub, busters and some others. . Now we will tell more about some of these species.


    This is one of the most common types of fish in Russia.Ide loves deep flowing water - rivers, streams and streams, of course, if they are deep enough. This is a very beautiful fish with silvery gold scales and a dark blue back. Fins usually have a reddish tint. An adult ide weighs usually more than a kilogram, and some specimens even reach a weight of 5-6 or even 7 kg. It spawns in April-May in large flocks. It feeds on aquatic vegetation as well as molluscs.


    So we got to the first river predator. A not too large (usually about 10–12 cm in length) ruff is a fish with large purple eyes, with a light yellowish color, belly and sides, and with a gray-green back. Practically any fresh-water reservoirs like ruffs, they only avoid places with a strong current and densely overgrown with aquatic vegetation. Ruff feels perfect in deep and cold water. It feeds ruff with other fish and fish fry. Spawning is usually in the middle of spring upon reaching 2-3 years. Ruffs live in packs and do not like to change their place of residence too much.


    This fish is a real decoration of the waters of the European part of Russia.Trout, which is quite different in its basic color, is easily recognizable by its shape and speckles (white, black and red), covering the body of the fish. As for the primary color, the darker it is, the deeper the water body in which the trout lives. Trout is a predominantly ground fish that feeds on small river wildlife - mollusks, worms, larvae and insects. However, in case of obstacles in the pond, this fish can easily overcome them, as it is able to jump out of the water to a distance of 1 meter. Trout spawn at the end of autumn, and the number of eggs laid by one female can reach five thousand. The average length of a trout is about 30-50 cm, and weight - from 500 g to a kilogram.


    This fish is found both in flowing waters and in ponds, which have a muddy bottom. A crucian carp is of two main types: silver and gold (more precisely, reddish-yellow), the latter being larger. Carp feeds on the same as the trout, namely - small river living creatures. Spawns in the spring. It is a rather heat-loving fish, which, however, lives in virtually every water body. The average length of crucians is about 15 cm, but there are also instances of 30 or more cm weighing more than 1 kg.


    This fish has a very wide and flat body and a small head with very mobile lips, which the bream can pull out into a tube, due to which it cleverly collects all kinds of food from the bottom. The size of the bream is much larger than the crucian. Adults can reach 50 cm in length and weigh up to 4-5 kg. A bream is a deep-water fish and rather cautious, therefore it is difficult to catch it. It is found in almost all Russian rivers, but prefers warmer water. Females of bream can lay 300-400 thousand (!) Eggs each. By the way, females are much larger than males, but the latter have a brighter color.


    Perch is one of the most common types of fish in Russia. It is not difficult to recognize a perch: bulging eyes, a dark green humped back with greenish-yellow sides and a yellowish belly. The average length of an adult hunchback perch is about half a meter, and its weight is about 2 kg. Smaller river perch-grassy weighs only about 150 g, and in length is about 10-12 cm. The perch feeds, like any predator, with live food - larvae, insects, bloodworms, fry. Perch spawning in flocks in May.


    It is time to talk, perhaps, about the most formidable river predator.To begin with, already a small pike as early as possible tries to leave the “parental home” and begins to live a separate life. Depending on the type of water body, the weight of a pike can vary from 1 kg to 10 kg or more. Deep pikes prefer to live and hunt in abandoned and remote places of a reservoir among stones and driftwood, while so-called grass pikes prefer overgrown and not too deep calm reservoirs. Pike spawns in April-May.


    Finishing the conversation about river fish, let's talk about another famous predator. The pike perch quite often is the companion of a pike, dwelling in the same places of exactly the same reservoirs. It is the largest representative of perciformal fishes, whose average weight is 5 kg and its length is about one meter. However, there are some individuals and up to one and a half meters in length and weighing up to 15 kg. Sharp teeth, spiky thorns on the fins - all this makes perch a formidable predator, but a narrow throat sometimes prevents it from swallowing wide enough prey - for example, bream fry. The pike perch, like many other fishes of the European part of Russia, does not spawn in April-May. The female pikeperch is capable of laying up to 30 thousand eggs.

    What are sea fishes

    With regard to marine fish, on the territory of our seas are distributed such species of commercial fish as salmon, herring, flounder, halibut, tuna, mackerel, saury and some others. What other fish are there? Some marine creatures are the most dangerous predators - including humans. These are, for example, various types of sharks. Also, nothing good is a meeting with such types of fish as moray eels or swordfish.
