Fish that feed on fish.

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.

River settlers

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

perch is both hunter and prey.It feeds on small fish, and he himself is food for pike and walleye.

Underwater vegetarians

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.

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:

fish living in the lake, has a slightly different diet than the river.This is due to the special microclimate of the reservoir.River fish predators such as whitefish their eating habits differ from the lake by the fact that the diet of most of them by 60% consists of phytoplankton and algae.

largest and Marsh voracious fish eat small crustaceans, phytoplankton and zooplankton - a carp.Like its river "brother", he never eats, because it is a fish without a stomach.Also, small crustaceans in large numbers eating bream.
