12.04.12.Nehvatka lake and Eric, as well as extreme cold this winter have led to massive fish kills in the Volga-Akhtuba floodplain. Fishery biologists fear that the situation could lead to the disappearance of pike, carp or roach and offer multiple address urgent environmental problems.
For the decomposed remains of fish. Already stuffed ants, birds porasklevali. A pile of dead remains of crayfish. Only the shells.
This sad situation is observed around the entire perimeter of the lake in the Leninsky district Beschastnykh. Experts bitterly ascertain mass death of fish and explain the reason for the tragedy: a total lack of water in the Volga-Akhtuba floodplain and severe weather conditions.
Vyacheslav Sorokin, a leading ichthyologist Department "Nizhnevolzhrybvod": "Prolonged cold, deep snow — they have contributed to the fact that water is a deficit of oxygen. It so happens that the oxygen deficiency affected the state fish and they died. "
Bream, carp, pike, roach, in recent years, and so are not encouraging fishermen great catch. In the past few years, the volume of oil produced in the floodplain fish declined by almost twenty-fold. A water level dropped to Beschastnykh meters.
Environmentalists and ichthyologists sounding the alarm — a pace once overflowing lake will turn into a trickle and not be able to supply drinking water to nearby villages and pets. And most importantly — the fish populations for eradication.
Artificial replenishment of the population size effect will not, say ichthyologists. So, you need to create the right conditions for the fish so that they can successfully survive the biting cold.
Sergei Yakovlev, head of the Office of ichthyologist "Nizhnevolzhrybvod": "If you artificially make wintering holes to depth of somewhere around 3 meters was, the fish would be in hibernation these holes remained. Plus spend another winter protivozamornye event — that is, additional holes through the hole, with shafts of cane supply, in order to ensure the normal supply of oxygen and air. "
And ichthyologists suggest bring the problem to the shallowing of lakes Volga hydroelectric power plant. If pump water directly into the river bed Akhtuba, we can supply all sources rather life-giving water.
