THE SIZE AND AGE CHARACTERISTICS OF THE CATCH AND BREAM GROWTH IN THE MESHINSK AND SVIYAZSK GULFS OF THE KUYBYSHEV WATER RESERVOIR IN THE PERIOD OF DESTABILIZATION OF ITS ECOSYSTEM

Abstract: 

The authors of the article study the size and age characteristics of the catch and the growth of bream in large gulfs of the Kuybyshev water reservoir in the period of destabilization of his ecosystem. It is shown that in 1996-2008, the average size of bream had a tendency to decrease due to the fall of the commercial catch, as well as the reduction of the share of senior-age individuals. The growth of bream in the Sviyazsk Gulf was better than in the Kamskiy Ples and the Meshinsk Gulf.

Key words: 

bream, dimensionally-age composition, growth, reservoir coves.
