Abstract: The fish diversity is a good indicator of health of aquatic ecosystem and represents the balanced ecosystem. The present study was conducted in Bugudanahalli Lake which is located in the south-east of Tumakuru district, at a distance of 08 km from Tumakuru city of Karnataka. It lies at 13° 36' 69" N latitude and 77° 04' 78" E longitude. It receives water mainly from rain fall an average of 620 mm. This underutilized fishery resources after immense scope and potential for generating additional national income by adopting appropriate management measures and fishery regulation principles. In recent years due to varied climatic conditions and disturbed rain fall impacts of human activity increases variations in ecosystem. At present there fish productivity is considerably low. No much reports are available on Bugudanahalli lakes. Keeping all these views, we have selected Bugudanahalli lake for study on fish diversity. Total 08 species of fishes belonging to 07 genera and 02 orders were identified from the lake. The order Cypriniformes was found to be dominant among fishes. Hence the protection of this lake is mandatory for sustainable fishery.
