So, only in 50-ies of our century from such poisoning suffered tysjacheletij. According to the researchers, only poisonous fish there are about 500 species, most of which live in the salty waters.
By climatic and geographical basis distinguish polar, Northern, temperate, subtropical and tropical zones. The majority of our population lives in Northern and moderate climatic zones and therefore are not familiar with the fauna and flora of the tropics. Year-round abundance of warmth in them contributes to the rapid development of wildlife. So, in the Amazon region, has about 15 thousand different species of animals. Continue reading

But the dead leaves of aquatic plants and the waste products of the fish will decompose in cold water and allocate detrimental to the inhabitants of the marsh gas pond.
For saturation of water with oxygen and removal of marsh gas must be cut in the ice hole and to ensure that they did not freeze. In no event it is impossible to break the ice with a hammer or other object. From the strong sound waves can hurt the fish.
