Spring spawning walleye


Depending on the temperature conditions in the pond, spawning walleye can begin as early as mid-April and late May. In the southern rivers, where the water is warming up faster, it starts in mid to late April, the same waters of central walleye spawning takes place later - in late May and early June. To spawn in the river water to warm up to 10.7 degrees Celsius, while achieving a temperature of the water is going to perch in the marriage group.

In this period of commitment to the rapids, shoals, and other places with strong current perch goes to non-relevant sites on the quiet parts of the river, with an extensive aquatic vegetation and almost no flow. For the marriage of walleye spawning generally choose a relatively shallow space - with depths of 0.5 to 4m. Even a 4-meter depth are exceptions, most spawning walleye are quiet places with depths of 1.5-2 m.

With the onset of walleye spawning shoals begin to search for a suitable substrate for sweeping caviar. It can be branched roots of reeds, sedges, roots of water lilies, and roots of various shrubs, riparian or submerged trees (alder, willow, and others). Cases when choosing walleye spawning flooded meadow grass with depths of 1 - 1.5 m.

Spawning walleye been very interesting. Each wedding band sander consists of one female and 2-3 males accompanying her. First of all females prepare nests. Stopping at a suitable spawning flooded roots, the female actively fanning the roots of fins, forming waves, and thereby removing, the remains of the soil from the roots. Then the whole group snout leveled the hard ground around the spawning grounds. As a result, around the roots is formed by an in-depth 5-10cm space in the form of an oval, which will clear out and caviar. The size of the nest depends on the size of the producers themselves, and can range from 25 to 60cm in diameter. Spawning usually occurs at night. Female sweeps once all eggs in one go, but in fertilization takes part in only one male, the rest ran. After spawning, the female swims away, and the male to fertilize eggs, it remains protected. It is called "watchdog" perch.

"Watchdog" walleye is near the spawning grounds as long as from the eggs begin to hatch larvae. The mission of "watchdog" walleye is very important during the period of maturation of eggs, he actively fans eggs fins, thus aerating and also prevents silting. If scare "watchdog" walleye, some time later, he returned to the nest. But if you catch, kill all eggs. In addition, the perch is not very prolific, the number of eggs hardly reaches 200 thousand for shedding.

Perch, despite its high strength in the many rivers, may have disappeared. Often in reservoirs and other large bodies of water simply no suitable places for spawning and breeding ground if not found, the eggs swept spontaneously, and will soon die. But walleye in troubled waters and is also easily possible to save - he willingly lays eggs on artificial spawning grounds.

After the end of the spawning occurs a short period of Jora. But this time is surprisingly fast ends and walleye bite continues unabated. Prior to the onset of spawning walleye few catches, its activity at this time is very low. Only with the onset of the first nibble of the May numbers it is satisfactory and is improving slowly until it stops at the spawning period. Peak biting walleye up in July and August, and then gradually worsens.
