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.

The smallest freshwater fish
The smallest and lightest freshwater fish is the dwarf pandaka (Pandaka pygmaea). This colorless and nearly transparent fish lives in the lakes of Luzon in the Philippines. The name of Pandaka pygmaea means in translation – the dwarf pygmy. Body length of males 7.5-9.9 mm, and weighs only about 4-5 mg. Along with this the smallest fish are also other types of goby that lives in the lakes filipin – Mistichthys luzonensis, Pandaka pusilla, Microgobius lacustris, reaching a length of 10-12 mm. Despite their size, these fishes are widely used in fried, mixed with spices, etc. often contains Fish in the aquarium. Pandaka pygmaea is listed in the list of endangered species.
Baensch in his Atlas indicates that in 1986, the record was broken by marine fish Trimmatom nanus.
The smallest commercial fish can be considered a fish sinarapan (Mistichthys luzonensis), a type of goby that are endangered and found only in lake Buhi O. Luzon, Philippines. Males reach 10-13 mm in length, and in order to obtain briquettes of dried fish weighing 454 grams required 70 000 fish.
The oldest fish
In 1948 Helsingborgs from the tank Museum, Sweden, announced the death of the female European eel (Anguilla Anguilla) named Patti, who was 88 years old. It is believed that she was born in 1860 in the Sargasso sea, North Atlantic ocean, and was caught somewhere in the river at 3 years of age.
In the records of European monasteries marked carp . lived up to 375 years.
In 1497 in a lake near Heilbronn (Germany) was caught a pike with a ring dated to 1230.

Rainbow fish Pseudomogul signifer . living in Eastern Australia and feels well both in fresh and in sea water.
Pike grow faster than any freshwater fish, except catfish
…not counting belomorskih Beluga and sturgeon, and with the exception of catfish. Reaching the magnitude of the yardstick, i.e. 5-6 lbs, we have a 4-5 year life, it increases in length slowly and grows more in thickness. Adult pike grows annually about polyverse. Forty-pound specimens have a length of about 2 feet long and must have at least 20 years, and often 30 or more.
Large pike caught in drainage ditches
When fishing for large European pike is not only the size of the reservoir. For example, one pike per 25 kg was caught in the sand pits. Fishermen on the marshes of the Scottish catch pike in drainage ditches with a width of 15 m!
