STUDIES ON THE SEASONAL VARIATIONS IN PROXIMATE COMPOSITION OF LABEO BOGA

Studies were conducted on seasonal variations in the proximate composition of Labeo boga ranging from 15±1.5cm L and 110±15gW, collected from River Tawi. During pre monsoon period i.e from Mar-May, the protein, lipid and ash contents were observed to be maximum i.e 17.54±0.31 for protein; 3.26±0.43 for lipid and 1.23±0.02 for ash; whereas during monsoon period (June-Aug), these energy reserves shows significant (p<0.05) decline as compared to pre monsoon season, with protein, lipid and ash content observed to be 16.46±0.64, 1.95±0.46 and 1.03±0.01 respectively. Further, the values of these energy reserves showed an increasing trend during the post monsoon season i.e from Sep-Nov; and thus protein, lipid and ash contents observed to be 17.21±0.17, 2.96±0.06 and 1.17±0.03 respectively. However, moisture content was observed to be higher in winter season (83.11±0.6) and least during pre monsoon season (77.22±1.98) owing to the higher temperature during pre monsoon season i.e from March-May, and hence more water loss from the fish body. The data thus revealed that nutritional quality of fish varies according to the season and thus results are of immense importance for human dietary.
