In Vinnitsa area the spawning season is a special time in the life of the inhabitants of the waters
Spawn – is a special and very important period in the life of the inhabitants of the waters, when they are breeding. And therefore, at this time, as never before, fish need peace and comfort. Spawning of fish is influenced by many factors, among which the most important is the temperature of the water. For each species of fish your temperature range. If the temperature is unfavorable – the water is too warm or too cold, the spawning may not begin or take part. From the abrupt change in water temperature can die the eggs and the fry that have already appeared. Even under an ice cover begins the spring fish passage. The majority of our freshwater fish spawning takes place from spring to early summer: April spawns pike, perch, Zander, from the middle to the end of may –bream, carp, crucian carp. Every kind of fish for spawning is a special place – the spawning grounds. The spawning of pike, carp, bream, pike-perch takes place mainly in the floodplains of rivers, on grassy shallows. Fecundity of the fish is different and is expressed in the number of eggs the female lays an average. The female carp, for example, lays up to 1.5 million eggs, and catfish – a total of about 500 pieces. Scientists have found that the carp 97% of the fry do not survive to three years of age, with 93% of eggs die within the first 7-10 days after laying, they eat other fish, amphibians, waterfowl, their blows over. Why is this happening? The fact that different species relate differently to the pending calf: or forget about it, or guard, showing concern. Those species that show no care for their offspring tend to lay their eggs off and caring parents, such as catfish and perch, protecting the masonry. In addition, some fish species spawning inherent in the portion is stretched in time, which also helps the survival of the offspring. One-time spawning is typical for pike, perch. A La carte – for carp and crucian carp. Therefore, the spawning season is a special time in the life of the inhabitants of the waters. And from how successful it will be, depends on the future of fish resources. So workers Vniizarubezhgeo call on concerned citizens, especially fishermen, not to remain indifferent to the violations of environmental legislation, to observe the rules of fishing and to prevent fishing during the spawning period. Our goal is not only to maintain but also to increase of fish reserves of water reservoirs in the region.
