Рыбы озера Выгоновского и их промысел. Сообщение I

Abstract

Vygonovskoe — the biggest lake in the Byelorussian Polesie. Its area is 2596 ha. 16 species of fish inhabit it. The investigated fish species by their morphological characters belong to the typical forms, except for subspecies Carassius auratus gibelio (Bloch. ) and Rhodeus serkeus amarus (Bloch.) . In 1953—1954 the lake was supplied with C. auratus gibelio (Bloch.) . It quickly propagated there and became a dominating species. In 1964 the catches of this fish reached 108 kg/ha or 76% of total catch. In the following years its catches somewhat decreased. There is a small amount of Abramis brama (L.) in the lake, the life conditions for it are kept by the lake water level in control.
