Silver carp, imported once from Kazakhstan (behind the ocean it is called Asian carp), has spread to the waterways of the New world with an incredible scale.

It all started with the fact that in 70-e years of the last century of American fishermen, not thinking about the consequences, brought a few specimens of silver carp and silver carp, which were caught in lake Balkhash to “imported” fish destroyed the excess of algae in the Illinois river.
