Beneath the ice

In November and December until the beginning of a hard frost, perches still walking in the shallows. Once the water covered with ice first film through it can be seen as a bevy of young perch scurry back and forth, grabbing the bottom of the ice surface of small crustaceans, amphipods, who sit there like flies on the ceiling. As the ice pulls all the polynya, water, even the flow begins to peter out oxygen. Breathing becomes difficult, and bass stops eating, becomes lethargic. After a while he seemed to get used to the lack of air and then taken to swim, pursues fry readily suited to the hole poglotat air. In early December extended spawning many salmon rivers over the fast rapids, some - on the lakes. Late autumn in the north of spawning lake trout spawning the so-called "Pereyaslavskaya herring (or whitefish), Peipsi whitefish, Volkhov, and some other whitefish Onega and Ladoga lakes. From whitefish in our middle lane can be found in whitefish Pereyaslavl lake and Lake Seliger. In January, the course begins and spawning burbot. Flocks raised it under the ice against the current until it reaches the shallow shoals and fast, with a gravelly bottom. Here burbot burst out in late January, its small, sticky, and very abundant eggs. Young burbot lays up to 200 thousand eggs, large - up to 1 million. Most of the winter, burbot is the active life and attacking the other fish. Only at the very beginning of the winter freeze-up after a sharp decrease in oxygen in the water and acts on it. He rises up, becomes covered with ice and stops eating. Two weeks, he needs to adapt to winter conditions. After this he again comes to life and begins his hunt. Still a little late to start the course burbot upstream. They are whole flocks and on the road do not stop to hunt for all the "water game", what they turn up. In such rivers as Mologa and Sheksna in January caught a lot of burbot. Here the course burbot is particularly noticeable. Fishing continues in February. In this deep sleep fall many carp fish: carp, carp, tench, chub. Dream deep, and they like to complete paralysis. The body is covered with a thick layer of mucus, which fishermen call "fur coat". Only a roach in hibernation does not fall out and feed on smaller sites. Winter torpor almost stops breathing, digestion and metabolism. This - a device that save fish freezing waters of the difficult conditions created by winter. This is especially important for pond and lake fish. Water muddy waters greatly impoverished in oxygen: here at the expense of dying decomposed remains of plants. At this time the "wild" ponds, where people do not care about the hole, happens is that fish farmers are called "frozen". Deprived of air flow, water is so "stifling" the fish in it begins to suffocate and die. Water is rotten, foul smell issues, and in spring, after the withdrawal of ice, fish corpses beaten by waves to shore. Once in March, will run from the shores of melt water, and bring new portions of the missing oxygen, underwater country begins to slowly come to life. Back in early March or even in late February wakes up fast chub. From deep wells, where chubs spent time with the onset of winter, they go into small places, and swim there in flocks. In March, they touch up against the current, slowly making his way to the headwaters. The same can be said about the dace and ide, who wake up in March, swim up to protayavshim outskirts of ice and also gradually starts to move upwards.
