A review on fisheries management and development in Bhadra reservoir, Karnataka.

Abstract

The development and management of Bhadra reservoir in Karnataka is reviewed based on published literature. In addition to fisheries the reservoir water is used for hydroelectric power generation and irrigation. The fish diversity, water quality, fish catch composition, craft and gear, vegetation, regulations, exotic species and habitat improvement factors are discussed. The fish diversity was low in pre-monsoon probably due to the shrinkage of the water spread of the reservoir. The high value of dissolved oxygen coupled with low biochemical oxygen demand and other nutrient levels indicate that the water body is moderately oligotrophic in nature. Water quality is highly congenial for fish life. Fish seed stocking is a major input in the management of reservoir fisheries. To save fishes and to develop a sustainable fishery practices and proper documentation leading to diversity information system is an urgent need.
