Evaluation of Proximate Composition and Seasonal Variations of the Muscle Tissue of Mouth-Brooding Tilapia Oreochromis mossambica from Meghadrigedda Reservoir, Visakhapatnam, Andhra Pradesh, India

Abstract

This study aimed to investigate the proximate composition and seasonal variations in the muscle of mouth-brooding tilapia O. mossambica from Meghadrigedda reservoir, Visakhapatnam. The bio-chemical analysis such as total protein, total fat, total carbohydrates, ash and moisture content in the muscle of fish was taken for seasonal variations in relation to reproductive characters during 2021-22.The total protein percent of the fish O. mossambica ranged from 24.5 to 36.8 in females and males was 24.5 and 37.5. The total fat percentage ranged from 5.4 to 8.6 in females and males was 6.4 to 8.7. Total Carbohydrates percentage was 4.1to 5.5 in females and males was4.8 and 5.9. Moisture percentage was 80.2 to 84.5 in females and males was 75.5 to 85.5. Ash percentage was 4.1 to 4.9 in females and males was 4.1 to 4.8. The results of the present clearly indicate that there was differences in the proximate composition of the male and female species.
