The pike is an important and necessary compo-nent of ecosystem. It is one of representatives of a trophic link of predators in Krasnoyarsk reservoir. The pike is not only biological reclamation expert, but also stabilizing factor which supports balanced structure of fish community. Fishing of the pike is possible as a by-fishing at production with the main trade species of fish. The results of researches of trade condition of the pike in the Krasnoyarsk res-ervoir are presented; their dimensional and age characteristics are given. Annual data concerning trade fishing of the pike in 2008-2014 are given. Sexual maturity and fertility of the pike are de-scribed. The growth of the number of population of the pike is possible only by artificial reproduction. Stocking of the pike in average and lower parts of the reservoir is especially necessary. The depend-ence of the number of the pike on the abundance of feed and existence of necessary substratum for postponement of caviar is studied. The ratio of the sizes and age of the pike in the Krasnoyarsk reser-voir is considered. In control catching the pike is presented by individuals 24-97 cm long and weigh-ing 112-9100 g, the age of fishes was from 1+ to 13+ years. Filling of the reservoir was carried out from February, 1967 to September, 1970. In the first years of filling of the reservoir flash of number of the pike was noted. The abundance of forage (young generation of roach, perch, dace), increas-ing in the spawning areas due to flooding of the floodplain of the rivers led to fast increase in the mass of fishes. Then recession of number of the pike connected with fluctuations of water level and insufficient quantity of vegetation was observed. The recommendations about the increase in the number of population of the pike were made.
