She prefers warm and calm.

In lakes, roach is found in shallow waters well warmed by the sun. The roach does not like wetlands and areas with silt content. Before cold weather, she swims to deep waters, where she stays for the winter. After floods and ice drift, this fish is found in reservoirs on floodplains.

roach spawning

Spring roach after the opening of the water tries to stay close to the shores. In rivers, it often goes to the floodplain and oxbow lakes. After the recession of the water, most of the roach remains in the same place. This fish tries not to go far from its own dens.

Food

Roach diet mainly consists of animal and plant foods. These are plant seeds, algae and other aquatic vegetation. The larvae, as soon as they emerge from the yolk sac, eat rotifers, crustaceans, insects and small bloodworms. The matured common roach begins to additionally feed on mollusks. The former food becomes secondary. Roach nutritiondiffers depending on its habitat.

spring roach

She feeds day and night. This fish is constantly on the move. Most often it can be found at midnight. During cold weather, during the winter, roach eat much worse, as it becomes more difficult to get food. But the roach is also active in winter and bites well. In cold weather, she usually swims near the muddy bottom and between the algae. In winter it feeds mainly on bloodworms and vegetation.

Spawning

Puberty in roach occurs two years after birth. Roach spawning begins later than ide, pike and some other fish species. But a little earlier than bream, catfish, pike perch and carp. In central Russia, roach spawns in the riverbed after the water subsides. In the Kama, Volga and Oka, this fish spawns in oxbow lakes and floodplain lakes. On the Don, the lower Volga and the Dnieper, the roach spawns until the flood. In the Don, she spawns early, in March.

The start of spawning depends on the water temperature. If the area is located closer to the south and the spring is warm, the reservoirs heat up faster. In this case, spawning starts earlier. Usually roach spawning begins in late April - early May. At this time, the water temperature already reaches from 10 to 15 degrees. In water bodies located to the north and in the Middle Urals, roach spawns in mid or late May.

Before spawning begins, roach is covered with a rash in the form of whitish spots. Then they become darker and harden. The scales become rough to the touch. Traces fromhard spots disappear a week after spawning.

Before spawning, female roach rise up in large flocks. The males follow them. Due to the fact that fish without milk and caviar are caught after spawning, it is assumed that the sexual products are spawned in one go and ripen at the same time.

large roach

Roach eggs are transparent, soft, with a slight green tint. They stick to pitfalls, snags, etc. The eggs are located very closely, and being on the moss, they look like bunches of grapes. The largest clusters can contain over 84,000 eggs.

The number of young roach depends largely on favorable environmental conditions. In stagnant water, spring storms are very fatal for juveniles, during which many eggs are washed ashore. The fry are not at all afraid of the unrest of the water, so they go to the depth only in June. In the rivers, many juveniles are carried away by floods.

Growth of young roach

Young common roach starts to emerge from eggs in a week, in warm weather. Often ten days after spawning. Less often - in two weeks. The fry swim close to the surface of the water. They feed first on their yolk sacs, and then on small plankton. First, the fry hide from enemies among the algae. There, she gradually begins to feed on crustaceans and plants. In the rivers, young roach is located near the baths, rafts. There she hides from predators and finds food.

In July, young fish begin to swim into the open water. She finally leaves the shelter in the formwater thickets in August. In autumn, the young go together with adult fish for wintering in deep pits. In some lakes, roach sometimes come to the surface for food even in late autumn.
