Opening of the swimming season in Dnepropetrovsk may not take place. Residents of Dnepropetrovsk live in jeopardy upcoming bathing season. The reason is extraordinary: in the waters of the river discovered crabs, jellyfish and very dangerous predators – piranhas. 
Photos from open sources At first there were rumors about the presence in the waters animals unusual for these places, and then fishermen, and ordinary people have personally verified that rumors are not unfounded: exotic living creatures in the Dnieper really lives. Fishermen not only made sure in the presence of “alien” fish, but also repeatedly caught them. On the hook for example, such strange representatives for the Dnieper came across water world like needle fish, piranhas and sea crabs. And it is not tales and not horror stories. According to the official – ichthyologist Roman Novitsky, who commented situation that urgent environmental engineering should be carried out Surveys, it became known who settled in the Slavic river. Lakes and the rivers of the Dnipropetrovsk region do not consider their habitat only 38 fish species familiar to this region, but also 18 species, absolutely alien to him. Some of the “strangers” are dangerous not only for humans, but also for ordinary inhabitants of these reservoirs. Quite it may happen that one of the bathers is bitten, and fishermen will be left without a catch. As for the catch – seriously: “foreign predators “gladly enjoy caviar of crucian carp, bream and carp, they themselves remain unsuitable for human consumption. Concerned about the situation and scientists. It seems to be nice that the species filling the Dnieper basin becomes more diverse, but, on the other aggressive aliens may well destroy local fish. What finally happened and why migrate to the Dnieper inhabitants of reservoirs of other parts of the world? Scientists find several possible reasons. Avariumists could release plecstomuses into the river, piranhas and ancistruses who found the local conditions suitable for life and began to multiply. Jellyfish most likely dragged on their bottoms of sea vessels, and high salinity attracted igloo water. Despite the ambiguity of the situation, experts still recommend not to fear swimming in the waters of the Dnieper. Exotic fish probably not so much, and they are small in size so that to harm a person. However, with all due respect to the opinion of scientists, people are still cautious: how can you swim, especially for children, if at least one piranha in the Dnieper is found?
