Fish Kaluga is very strong, that's why it styled the Amur tiger.Tail it can knock the rivets out of the seams of the boat.But it has a weak point - turning the fish on the back, it can do anything.
Naturally, such a big fish - predator.When salmon, smelt, chum salmon, herring are spawning, Kaluga is attached to the flocks of swallows and five-kilogram fishes, like a small bird swallows fly.At other times, she may eat small fish, marine shrimp, and even their own young.
Old fisherman from Mykolaivka-na-said, accidentally caught Kaluga.They were delivered to the network 3, in which the fish hit.She tore the network 2, exhausted, confused in the third.Fisher had to hire a car and secure network of steel cables to pull this edifice on the shore.Proceedings have appeared vain.Of fishes got a barrel of caviar.

Over the past half century the number of Kaluga dropped significantly.This was due to uncontrolled poaching catches, as well as pollution of water habitats.For some time, catch the super-fish has been banned.Currently, fishing is limited, so the population is gradually recovering.
Fish Kaluga scientists are very interested in its long migration, and the ability to live in both freshwater and marine.
