In anticipation of the end of the spawning season (May 25) at Dnepropetrovsk in a backwater of the river Samara, local residents discovered tons of dead fish. In place of the state of emergency immediately left special commission of the regional administration and environmental inspection.
Curiously, the true scale of the tragedy, environmentalists still can not assess. "We assume that there are not more than 10 tons of dead fish, but residents of neighboring villages said that even a few days before, they also observed a dead fish. Her drifts downstream in the direction of the Dnieper (Samara flows into the Dnieper near f / m Pridneprovskiy) .
And the most unusual that killed only one kind of fish — carp. And the dead birds — only adults (4 to 6 kg), "- said the inspector gosoblekologicheskoy inspection Vadim Steshenko and added that the samples delivered to the laboratory, which will find out the cause of death of fish. According ecology, industrial kill fish is unlikely to have attitude, because in that place no factories, said today.
But the local fishery biologists believe that the massive fish kills occurred because audacity poachers. "The death of fish — in these places not uncommon. Sometimes this happens when the fish in the heat of a lack of oxygen, but in this case all seem to use the poachers elektroudochek. With these devices, you can kill all living things in the water within a radius of 10-15 meters. Moreover, the larger the fish, the more vulnerable it is, "- said ichthyologist Roman Novitsky. According to him, during the spawning season in the Samara plant a lot of fish and almost all of it, along with crayfish, frogs, and even algae died.
The real extent of the plague is difficult to assess, because about 20% of dead fish sink to the bottom, where begins to decompose. "The worst thing is that surviving individuals will never come to spawn in these places. Fish have a memory that it does not return to where it was bad," — said Nowicki.
Ichthyologist believes that kill many fish and even in spawning — a crime. "We have reduced the fish population due to poaching, industrial emissions, power saving treatment plants. We are ready to write the Red Book of Dnipropetrovsk region, which will include endangered species of fish," — concluded ichthyologist.
