Chekhon fish. Chekhon fish lifestyle and habitat

Most fish are eaten in one form. Many are good at fried, some tasty smoked, salted, dried, some well cooked ear. But there are such universal fish from which you can cook anything, and any dish will be delicious. It is considered such a fish and chekhon.

The appearance of the sabrefish

Chekhon belongs to a large family of carp fish. This is a flocking, semi-aisle small fish living in fresh water. Outwardly, it is a rather interesting fish, and its main distinguishing feature is a very small shiny scale, as if covered with silver. On the sides, the body is strongly compressed, the head is small, with large eyes and a mouth curved upward.

In addition, the shape of her body is quite unusual - her back is completely straight, her stomach is convex. Because of this features chekhon also called a saber, saber, side, Czech. On the abdomen there is a keel, on which there is no scale. The color of the fish scales on the back is greenish or bluish, the sides are silvery.

The fins of the back and tail are gray, the lower ones with a reddish tint. The pectoral fins are very large, for fish of this size, and in shape they repeat the body of the sabrefish. The sensitive organ is the lateral line, located in a zigzag shape, close to the abdomen.

Czech fish is small, with a maximum length of 60 cm, weighing 2 kg., But such individuals are considered to be captured species, as they are quite rare. On an industrial scale, smaller individuals are mined - the usual size for them is 20-30 cm in length and 150-200 grams of weight. It is these small Czechs that can most often be bought in the store in a dried or smoked form. Sun-dried Chekhon very tasty fish.

Chekhony habitat

Chekhon is a semi-fish in the basins of the Baltic, Aral, Black, Caspian and Azov Seas. Mostly lives in fresh water, although it can survive at any salinity and creates living forms in the seas.

Chekhony habitat very large - its permanent habitat includes Russia, Poland, Germany, France, Romania, Hungary, Bulgaria and many other countries of Europe and Asia. The most numerous in the rivers are the Dnieper, Don, Dniester, Danube, Kuban, Western Dvina, Kura, Bug, Terek, Ural, Volga, Neva, Amu Darya and Syr Darya.

If we talk about lakes, then a large number of it lives in Onega, Ladoga, Lake Ilmen and Kelifskie lakes. Inhabits and some reservoirs. Despite its large range, in some regions chekhon refers to endangered species and is protected by the authorities. These areas include the upper Dnieper in the Bryansk region, the North Donets River, Lake Chelkar.

Chekhon prefers medium and large water bodies, in small rivers and lakes it is not found. Selects deep areas free of thickets. Sometimes he spends time on the shallows, but only if there is a rapid current. Loves places near whirlpools and rapids. There are no fish walking near the shore.

Chekhon lifestyle

Saber fish is active, lively and not fearful. During the day he constantly moves, but he does not depart far from his permanent "place of residence". In the summer, fish rises to the surface of the water during the day, in search of food. At night, it sinks to the bottom and hides there in various shelters, uneven bottoms.

The same after autumn cold snap chekhon kept at a depth, and spends the winter months in pits and whirlpools, lying there in packs of dozens of individuals. If the winter is not too harsh, then the schools of fish move little by little, while in strong colds they firmly lie at the bottom, practically not eating, so at this time catching chekhony not practiced.

In the spring, the Czech girl gathers in large schools and goes to spawn. In the fall, it is again grouped in flocks and preparing for winter. During this period, she leads a very active lifestyle and feeds a lot.

Chekhon food

Chekhon actively feeds in the daytime with both plant and animal food. It happens, in the summertime, jumps out of the water to catch insects circling above it. Young fish feed mainly on zoo and phytoplankton. And growing up he eats larvae, worms, insects and fry of various fish.

If she simply picks insects from the bottom or catches above the water, then she has to hunt fry. The Czech often swims with victims in one flock, then quickly grabs the prey and goes to the bottom with it. After comes back for the next. This lively fish attacks eagerly and quickly.

This feature of it is known to fishermen, they also know that the sabrefish is almost omnivorous, so they use almost any insects as maggot, maggot, dung worms, flies, bees, grasshoppers, dragonflies and other animals. In addition, the fish can peck on an empty hook, only tied with a red thread or on which a bead is worn.

Breeding and life span of sabrefish

Chekhon can reproduce in the state for 3-5 years of life (in the southern regions a little earlier - 2-3 years, in the northern regions 4-5). Spawning begins in May-June, and a small fish does this earlier than large individuals. The main condition for the start of spawning is a water temperature of 20-23 Cº, therefore, again in the southern regions, spawning begins earlier.

Before spawning, the sabrefish eats very little, gathers in large shoals and looks for a place to lay eggs. Areas with a fairly intense course and depths of 1 to 3 meters are suitable, these are shallows, sand spits, river rapids.

Spawning occurs in two calls in the south, and at a time in the northern regions. In the rivers Chekhon spawns, moving upstream, then rolls back down. The eggs are not sticky, therefore, they are not attached to algae or other objects in the water, but roll down to the bottom.

They have a size of 1.5 mm. in diameter, then, after fertilization, settle to the bottom and swell there, increasing in volume to 3-4 mm. Depending on the water temperature, eggs ripen in 2-4 days, then 5 mm fry hatch from them.

The fish grow quickly, feeding on the supply of their yolk, stray into small flocks and migrate with the flow. After 10 days, they switch to plankton, and feed on it for a long time. Chekhon grows very quickly the first 3-5 years. Then growth slows down, therefore, despite a life span of about ten years, rarely managed to catch a very large individual.
