North sea bass

Everyone who ever was fond of scientific and popular works about animals, probably more than once met the stories about the huge pike that supposedly lived several hundred years. The most popular is the history of the so-called “kalbrosky the pike”, which was supposed to have been caught personally by the Emperor Frederick II, marked with a gold ring and released at 1230 in one of the lakes where caught running through 267 years. Despite the seeming plausibility of these stories, today reliably established that all of them should be classified as legends or fishing tales. The maximum age of pike, like most other fish, usually no more than 20-30 years. There are, however, fish are long-lived, and these include fairly common off the coast of Kamchatka Northern sea perch.

This perch is the highest among other fish of the North Pacific ocean lifetime, which, according to many domestic and foreign researchers, reaches not less than 45-50 years old. However, some American scientists estimate the maximum age of Northern perch 140 (and even 200) years, although it is difficult to imagine in our time, with fairly intensive fisheries, the fish can live to such old age.

Shortraker rockfish is one of the most groupnameattribute of sea perch in the North Pacific ocean, which sizes up to 120 cm and 20 kg. It is found along the Pacific coast of Kamchatka at depths from 90-100 up to 900-1000 m, concentrating mostly in the range 300-600 m on the continental slope areas with sudden changes in depth and complex topography. But the greatest catches of Northern bass notes all the same in the Western Bering sea near the Cape Olyutorsky and on the underwater Shirshov ridge. It was here in the first half of 90-ies in Kamchatka the catches of longliners registered copies length 112-116 cm with a weight of 20-23 kg.
