The characteristic is given of morphological characters, growth rate and catch oi
 predatory and some other species of fish in lake Vygonovskoe. As to the data of fishery
 statistics for 1955—1967 the following species are of the greatest importance: Carassius
 aura/us gibelio (В 1 о с h) — 55.5%; Esox lucius — (19.1 %); Rutilus rutilus (L.) — 5.45%: C. carassius (L.) — 13%; Abramis brama (L.) — 0.64%;Perca fluviatilis (L.) — (0.39%).
 As a result of repairs in the Oginsky canal and the lock the water level in the lake
 became 0.5—0.6 m higher. This created an additional spawning and fattening area, which
 makes it possible to increase with acclimatization of Carassius auratus gibelio the fish
 productivity in the lake from 13.5 kg/ha in 1948—1954 to 62.8 kg/ha in 1955—1967 at
 an average. C. auratus gibelio and Esox lucius as well as Abramis brama, when regulating the water level should be considered as promissing fishery species for the lake.
