Biochemical Composition and Gonadosomatic Index of Three Major Carps in Hatnoor Reservoir, Maharashtra, India

Three major carps captured from Hatnoor reservoir were studied over a period of June 2008 to May 2010 to evaluate seasonal changes in muscle biochemistry and gonadosomatic index (GSI). During pre-breeding, breeding and post-breeding seasons, each fish species were captured and samples of muscle tissue were collected and processed for estimation of its protein, lipid and glycogen content. Weight of body and gonads of each fish species were noted. Protein, lipid and glycogen content in muscles of each carp species exhibited seasonal variations. The protein and lipid contents of three fish species showed successive decrease in their estimated values during the study period (
