Our planet is populated by representatives of the amazing fauna, each of which has its own unique qualities.We know a lot about them: for example, the koala does not drink water, cats perfectly see in the dark and dolphins possess almost human intelligence.And what we know about fish, except that there are edible, and there are all inedible and even poisonous?
In this article we will tell about the amazing inhabitants of the underwater measurements have fins: about their lives in the depths, and the habits of what the fish are fed, depending on the environment in which they live.
You will discover the unknown world of the underwater kingdom, which does not so calm and peaceful as it seems at first glance.For example, in the waters live fish, feeding on fish and small animals.There are also birds and animals rybolyuby who are not averse to eat freshly caught delicacy.
each his own menu
By the nature of the behavior and eating habits of fish are divided mainly on predatory and peaceful.Carnivores - a fish-eating fish, and only sometimes used different food.They represent a serious threat to fish-vegetarians, especially those of small size.
peace, in turn, are herbivorous, benthophages and plankton.Basically, it's the fish that feed on algae.
exclusively herbivorous consume phytoplankton, in other words - floating algae.Benthophages - a fish that feed on algae that grow on the depth (called phytobenthos) and organic particles.Plankton and zooplankton prefer not disdain single-celled organisms that inhabit the river.
In addition, there are omnivores euryphages - fish that feed on fish, algae and small invertebrates.Their menu is more diverse.
Looking at the river, we have no idea how many lives of all kinds of living creatures under the water surface.For each area characterized by its "sets" of freshwater fish.For example, in the rivers on the territory of Russia are found such representatives as Bersh, carp, dace, ruff, sturgeon, trout, whitefish, grayling.
also in Russian waters can be found smelt, pike, carp, bream, chub.In addition, there are so beloved by anglers carp, minnows, carp, roach, rudd, tench, catfish, burbot, perch.And this is not a complete list of all kinds.
Carnivorous predators river
what to eat fish in the river?Each of them has its diet.Menu river inhabitants depends on many factors: the type of bottom (sand or stones), algae, and even the time of year.
Let's start with the classic predators, which include fish, feeding on fish.It Bersh, sturgeon, trout, pike, catfish, eel, river perch.Consider them:
- Bersh belongs to the family Okuneva and looks very similar to walleye.This gregarious predatory fish that eats fry of roach and Rudd.Do not hesitate to take small minnows and ruffs.
- Sturgeon belongs to the family of the same name.This is an aggressive predator that can dine the main menu and "bite" frog.The river is a large number of sturgeon occurs only when they spawn.These checkpoints fish-eating predators, not only in fresh water, but in the salt.
- Loach - a very large representative of the salmon family, which is considered a predator because it is very fond of fish eggs, sour cream it in large quantities, thereby reducing their population to catastrophic proportions.Also trout prey on juvenile salmon.
- Pike - the only representative of the family of the same name.It is extremely aggressive, voracious, predatory person.The ration its supply rybёshki includes such as carp and roach.In addition, the pike "suffering" cannibalism: the predatory fish eat smaller representatives of their kind.The variety of the menu can make pike and small mammals (eg, mouse), happened to be in the water.Also pike prey may be small aquatic birds and their young.

- Burbot Cod belongs to the order.These fish predators hunt prey at night, and eat not only fish, including juveniles like themselves, but also decaying animals and frogs.
- perch is both hunter and prey.It feeds on small fish, and he himself is food for pike and walleye.
Civilians river depths - harmless fish that feed on algae, phytoplankton, detritus.Phytoplankton - a tiny plant organisms that inhabit a huge number of water bodies and is moved by the flow.
phytoplankton often not visible to the naked eye, so people do not give it a value.Many of us are not even aware of these microscopic organisms, and yet they - overriding vegetarian constituting what feed the fish in the river.This is especially true for species such as carp, carp and tench.Learn more about them:
- Cupid - "native" of the carp family.It feeds exclusively on vegetable food: mud, various algae, reeds.He can also use the submerged during the flood land plants.
- carp belongs to the same family as the carp, and prefers microscopic algae and detritus.Roth carp - a kind of "filter device", thanks to which this fish green water filters, as a kind of river sanitation.
- Lin - very sedentary fish prefer to live at the very bottom or algae thickets.More than 60% of its diet are algae.
interesting that almost all owners of fins, whether peaceful vegans or carnivores carnivores in the period of active growth are omnivores.The feed on fish in the river, which are classified as euryphages?The answer is simple: almost everything that gets into their mouth.This small river plankton, crustaceans, molluscs, protozoa, and even insects!This is especially true of young animals.High-calorie food - is an important element, which requires growing up fish.
eat insects, "young" does not necessarily become predators, and who eat the algae is not always the fry grow herbivorous.However, there are a number of fish that retain "omnivorous" Lifelong:
- Elec - "native" of the carp family.Eat bottom dwelling invertebrates, as well as vegetation and insects.
