Nutritional profile of climbing perch (Anabas testudineus Bloch, 1792) muscle tissue with emphasis on seasonal variations

Varghese, Treesa ; Mathew, Saleena


Nutritional profile of Climbing Perch (Anabas testudineus Bloch, 1792) muscle tissue were analyzed with emphasis on seasonal variations. Climbing Perch muscle tissue had high lipid content, constituting about 12.87%. The mean value of protein, moisture and ash were found to be 15.46, 68.86 and 1.25%, respectively. Highest values were observed in the month of March and April for protein (17.02%) and lipid (14.06%), respectively, while lowest values were in the month of July for both protein (13.02%) and lipid (11.08%). Highest and lowest values for water content were noticed in the month of July (73.37%) and March (66.91%). Protein (P <0.01) and lipid (P <0.01) content showed a negative correlation with moisture content within the muscle tissue. Additionally, between protein and lipid a positive relation was observed (P <0.01). Ash content showed no significant correlation with protein, lipid or moisture content in the muscle tissue and its maximum value was noticed in the month of March (1.75%). The results suggested that the proximate composition of fish muscle tissue significantly varies during different seasons. The present studies thus provide information on variation in proximate composition of the Climbing Perch with seasons which is useful for the processing industry.
