 ABSTRACT

The present study deals with the comparative account of water quality, diversity and population density of molluscans in two water bodies of Gulbarga and Bidar districts. This study was undertaken for a period of two years from October 2001 to September 2003. Eleven species of molluscan identified for both reservoir of which eight are gastropods and three belongs to bivalves. Among the gastropds Lymnaea luteola, Lymnaea acuminate, Melania (Palitia scabra), Melania scabra var elegans species and among bivalves Parreysia corrugate var nagvorensis, Lamellidens corrianus species were dominant in Karanja reservoir. While, in Khaji Kotnoor reservoirs, Melania scabra var elegans, Diogoniostoma pulchella, Lymnaea luteola, Lymnaea acuminate species, Bivalves Parreysia corrugate, Lamellidens corrianus were dominant species.   All the physico chemical parameters are within the permissible limit. Statistical analysis for Correlation and Shannon Weiner diversity index is also discussed in the paper.

Keywords: Karanja Reservoir, Khaji Kotnoor Reservoir, Diversity, Physico-Chemical Parameters Gastropods and Bivalves.
