STUDY OF VARIATION IN BIOCHEMICAL COMPOSITION OF MUSCLE TISSUE OF MUD CRAB Scylla serrata COLLECTED FROM GUJARAT AND MAHARASHTRA STATE, INDIA

In present study, biochemical composition of mud crab, Scylla serrata collected from seven local fish market of Gujarat and Maharashtra states was analysed to check the variation in their nutritive value. Total 10 individuals were collected from each fish market of study sites like Sartanpar, Bhavnagar, Bilimora, Amalsad, Versova, Gorai and Pen. Major biochemical components like moisture, protein, carbohydrate and total lipid content were estimated in body and claw muscles of the male and female specimens using standard protocols. Biochemical composition of studied species was variable amongst different study site. Moisture (83.81 ± 7.87%), protein (47.7 ± 21.74%) and lipid (4.03 ± 2.83%) were recorded maximum in body muscle of female collected from Bhavnagar whereas maximum carbohydrate (11.72 ± 2.35%) was recorded in body muscle of female collected from Amalsad. Present data shows that nutritive value of body muscle was higher compared to claw muscle tissue. The study also suggests that females were more nutritious as compared to male. Variation occurring in biochemical composition of S. serrata collected from various may be due to the effect of geographical area, the environmental factors and available food resources.
