Состояние экосистемы озера Ковдор и характеристика рыбной части его населения

Abstract

Представлены материалы по состоянию биоты озера Ковдор (Мурманская область), испытывающего влияние стоков Ковдорского горно-обогатительного комбината и хозяйственно-бытовых сточных вод одноименного города. По химическому составу воды озера относятся к сульфатному классу, по гидробиологическим показателям к ß-мезосапробному типу. В условиях антропогенного эвтрофирования и субтоксичного загрязнения наблюдаются высокие структурно-функциональные показатели сообществ всех трофических уровней, выявлена популяция европейской ряпушки с предельными для мелкой формы размерами.

The materials on the biota of Lake Kovdor (The Murmansk Region), affected by the Kovdor"s Mining Plant wastewater and domestic sewage are given. According to the chemical composition, the lake water belongs to sulfate class, according to the hydrobiological parameters to ß-mesosaprobic type. Anthropogenic eutrophication and subtoxicological pollution result in the high structural-functional charecteristics of communities of all trofic levels. Population of European vendace with size limit for small forms.
