BASIC ASPECTS OF ANTHROPOGENIC INFLUENCE ON ICHTHYOFAUNA OF ZAPOROZHSKOYE RESERVOIR

BASIC ASPECTS OF ANTHROPOGENIC INFLUENCE ON ICHTHYOFAUNA OF ZAPOROZHSKOYE RESERVOIR

Abstract

The reduction of body mass at fishes from toxobic areas of Zaporozhskoye reservoir is exposed on 32-58%, relative mass of liver and spleen — on 40-82% and that of gonads — on 23-68%, that testifies to certain functional violations in an organism. Biochemical composition of tissues of fish from contaminated areas was characterized by falling of carbohydrate supplies and accumulation of fats in liver on background of synthesis oppression of proteins and lipids in muscles. Anthropogenic influence on Zaporozhskoye reservoir ecosystem is reflected in substantial changes in fish parasitofauna. Parasites of genus Diplostomum and Philometroides havegot the epizootic value in the last few years.

У риб із токсобних зон Запорізького водосховища виявлено зниження маси тіла на 32-58%, відносної маси печінки і селезінки на 40-82% та гонад на 23-68%, що свідчить про певні функціональні порушення в організмі. Рибам із забруднених дільниць властиве падіння вуглеводних запасів і накопичення жиру в печінці на фоні пригнічення синтезу білка та ліпідів у м’язах. Антропогенний вплив на екосистему Запорізького водосховища супроводжується суттєвими змінами у паразитофауні риб. Епізоотичного значення за останні роки набули паразити родів Diplostomum та Philometroides.

Представлены результаты многолетних исследований морфо-физиологических, биохимических и паразитологических изменений у рыб промислового комплекса Запорожского водохранилища, обитающих в зонах с повышенным антропогенным влиянием. Выявлены деградационные изменения в структуре ихтиоценозов, снижение массы тела и относительной массы печени, селезенки и гонад, падение углеводных запасов и уровня белка в тканях и изменение качественных и количественных показателей паразитофауны у рыб из токсобных зон.
