There comes what is called "spring course" fish. Some breeds, he begins under the ice. Fish swim aggressively to the headwaters of rivers. With the tide fish flock out of the muddy stream channel in a more clean water - at the busy bottling poemnye meadows. Over there slowly ooze gradually settles and the water becomes lighter. Spring course closely connected with the approach of spawning, and has a deep biological basis: it is important to sweep eggs as close as possible to the sources of rivers. After weak fry will inevitably communicate down quick spring flow. If it were not for this pre-climb, all the fry would have been blown into the sea. In the first half of April, the spring move the fish develops with increasing force. In the lower reaches of rivers flowing to the south, such as the Volga, Don, Dnieper, the course begins in February and quickly spread to the upper. In late March, is a friendly course of walleye in the Lower Volga. Even under the ice begins the course of roach (Caspian roach), behind her - cruising in small circles, bream and whitefish, and with the opening of the river - starlet. In the middle lane too early to spawn (spawn), pike, dace and chub. Pike spawning begins immediately after the break-up. When the river beyond its banks and poured into poemnym meadows, pike move from the muddy river stream in a quiet and bright, the water spills. Here on the flooded meadows poemnyh schuchi start the game. Females lay eggs in the river oxbow lakes, puddles and lakes, remain on the shore, when the excess water returns to the riverbed. Around mid-April, anglers hunt on flooded meadows to the flared pike from prison. At this time, harvested the largest instances of pikes. Young pike spawn earlier, the old later - at the same time with the frogs. Dace lay eggs in small rivers - in the water-drenched coastal grasses. When rivers enter the coast and the water becomes light, begin a three-year spawning chub. They toss their orange and very small eggs on the fast river rapids - where the river runs over the stones. Smart recovery occurs in the water in the second half of April. Begin to move past, are not awakened yet, fish. Swim out of the pits sluggish catfish. Som do not like muddy water. During the flood, he goes up the river, overlooking the flooded meadows in the floodplain of the lake and captured high-water oxbow lakes, where the flow is not present or is very weak. There, in the late light and water, outwaits catfish, when will settle vzbalamuchennaya a river turbidity. A little earlier out of the pool and koi wells, sometimes wintering alongside somami. In the last third of April spawns ruff. Collected ershi flocks of hundreds to several thousand pieces. All of them at this time are restless and frisky. The main concourse has come in the evening. In the dim light of dusk ershi swim back and forth in circles. Ershihi produce fine caviar, ershi males - milk, so all the river bottom at the place where the spawn, as if covered with jelly. In this case, all is vanity, pushing and even jump over each other. During flood ershi often turn into a backwater and flooded the lake, where some of them remain until next spring. Almost at the same time as the ruff spawns and ide - and mostly at night. At dawn, you can still see the continuation of their wedding games: lively leaps and bursts of water shooting out of the males. In shallow areas with rocky bottoms are small fish, called bulls, as well as sculpin - for their ability to skillfully hide under stones. Sculpin kept in seclusion. Even during the spawning season, which begins in April and lasts until mid-May, he was not going in flocks, as do most fish. Goby exhibits instinct to protect offspring, that fish is pretty much a rarity. This instinct is peculiar only to the male. Before spawning the male pulls the tail fins, and partly an indentation in the sand under some rock and waiting for females. At that time he became extremely combative and fiercely attacking all the other fish who dare to approach its nest. When a female he lures her into her nest, where she puts a pile of eggs, a relatively very large, red-yellow color. In the pile is between 100 and 300 eggs. They are immediately fertilized by the male. After this, the female swims away, and the male remains to guard spawn. He has to wait more than a month until vyklyunutsya small fish. All the while he eagerly defends nest from any real or imagined enemy. Its spiny fins, gill covers with spines and rage attacks make a bold fish dangerous opponent for any other medium-sized fish. He throws even the rod or stick, which he substituted.
