Studies on the seasonal fluctuations in the proximate body composition of Paratelphusa masoniana (henderson) (female), a local freshwater crab of Jammu region

Abstract

The freshwater crab, Paratelphusa masoniana was collected for a period of one year to investigate the seasonal fluctuation in the proximate composition. Marked seasonal variation in protein, lipid and moisture were observed during a period of one year to determine their viability in the course of the reproductive cycle. Both protein and lipid content are inversely related to moisture content. Maximum protein (62.15±0.30%; 55.85±0.48) and lipid (5.85±0.46%; 5.49±0.38%) were observed during non-spawning period and minimum during spawning months. The relationship between protein and lipid is however a direct one. On the basis of the investigation, it has been recorded that the local freshwater crab, P. masoniana, is a biannual breeder. © Maxwell Scientific Organization, 2013.
