Proximate composition and its seasonal variations of the muscle tissue of Channa striata from Krishna river, Andhra Pradesh

Abstract

The present study was conducted to determine the nutritive value in terms of proximate composition and seasonal variations in muscle of Channa striata from river Krishna, Andhra Pradesh, India.The biochemical composition such as protein, fat, ash and moisture content in the muscle tissue of fish has been carried out during 2021-22 to know the seasonal changes in relation to reproductive biology.This fish has excellent sources of high quality proteins and nutrients with medicinal value.The composition of protein, fat, moisture and ash contents showed variations in their abundance in different seasons in both females and males.The highest content of protein 24.3±2.2% in south west monsoon and lowest (20.4±2.1%)recorded in North East monsoon in case of females and males was 25.2±2.4% and lowest (22.3±2.2%).The highest content of fat content was 5.4±0.4% was observed in North East monsoon and the lowest (4.3±0.4%) in case of females and males was 5.5±0.3% and lowest 3.6.The highest moisture 83.8±6.4% and was observed in south west monsoon and minimum 80.2 recorded in summer in case of females and males was highest 84.2±6.3% and lowest recorded 80.4 in summer.The ash content was highest 2.19±0.06% in post monsoon and lowest 1.61 in summer in case of females and also males was highest 2.25±0.063%and lowest 1.65 in summer.
