These amazing fish of fresh water

The record can be considered several kinds. The biggest freshwater fish is the Beluga ( Huso huso ), bone-cartilaginous fish of the family Acipenseridae. Its length reaches 4-5 m, weight is 1 400 kg.

Pike reaches enormous size and great age. Budovou pike can be found everywhere. We have the most big pike are found in Northern rivers and lakes, probably because of their less availability in comparison with southern.

The biggest pike ever caught – it’s historic pike Emperor Frederick II Barbarossa, commissioned them, as recorded on the ring, in 1230 in one lake near Heilbronn and pulled a Seine in 1497, i.e. through 267 years. With age the fish is completely white. Its size was 19 feet, i.e. over 8 yards long, and it weighed 8 pounds. 30 pounds. The portrait of this pike still in the castle of Lautern, and the skeleton of the ring is in Mannheim.

In the XIX century in Russia was caught ordinary, or European catfish (Silurus glanis) with a length of 4,6 m and a weight of 336 kg. In our day any freshwater fish that is longer than 1.83 m and weighs 90 kg, is already considered large. According to the famous zoologist Bram, the length of the fish reaches 3 meters and a weight of 230 kg, however, according to other authoritative sources, these figures are clearly underestimated.For example, encyclopedic dictionaries claim that the length of the catfish reaches 5 metres, and an American zoologist David Wheeler in his book “Fish killer” refers to a figure of 6.3 meters. In some waters caught specimens weighing up to half a ton. Catfish live in all major rivers, lakes and reservoirs of Russia and CIS countries – from the southern borders to the Far East. Soma is also distributed in Europe – except the Nordic countries. Continue reading
