Seasonal variation in the protein composition of Rastrelliger kanagurta (Cuvier) from within PFZ and outside PFZ at Sakhri-Natye fish landing centre on the coast of Ratnagiri district at Maharashtra state.

Abstract

The protein content in the muscles, liver and gonad of Ratrelliger kanagurta from Sakhri-Natye fish landing centre at Ratnagiri district coast was studies from Within Potential Fishing Zone (PFZ) and Outside PFZ. The protein study analyzed that winter and summer season. the protein content was increased in male muscle than female muscle, gonad and liver respectively within PFZ than outside PFZ. The protein contents in the body muscle, liver and gonad of Rastrelliger kanagurta (Cuvier) were investigated. The compositions varied seasonally in relation to reproductive cycle of the fish. The study also showed that protein was high in the muscles and gonads and in liver from within PFZ than outside PFZ in female and male.
