BETA DIVERSITY OF CYPRINIDS AS INDICATOR OF SHIFTING FISHERY ZONATIONS IN DAMODAR RIVER
131 / 0
Abstract
Alpha, beta and gamma diversities are used for measuring biodiversity of an ecosystem. Damodar river in India receives wastes and effluents from coal mines, coke oven plants, steel plants, thermal power station, fertilizer and cement factories, chemical industries etc. in its flowing path in the states of Jharkhand and West Bengal over the years. As a result of which alternation in environment and fish species diversity occurred in the river system. The present study aimed to measure cyprinid species diversity in a selected stretch of Damodar river to find out shifting in fishery zonations due to entry of industrial and domestic effluent in it and presented here.
Key words: Cyprinid species diversity, measurement, Damodar river, India.
