Our present work is based on the estimation of lipids in different tissues of silver carp fish (Hypophthalmichthys molitrix) such as liver, kidney and intestine. The lipid contents were measured in two weight groups 1-3kg and 3-5kg from Gobind Sagar Reservoir Bhakra and Nanoki Fish Farm. The maximum lipid contents were found in liver during summer season 10.04±0.04 and 12.87±0.02 and 14.44±0.05 and 16.81±0.03 form Gobind Sagar and Nanoki Fish Farm in 1-3Kg and 3-5Kg weight groups respectively. In kidney and Intestine, same pattern was recorded. Total lipid content value in kidney was 8.36±0.02 and 9.89±0.03 for 1-3kg weight group in kidney from Gobind Sagar and Nanoki Fish Farm and 11.77±0.02 and 12.84±0.02 in 3-5 Kg Weight groups respectively. Intestine also recorded the highest value of total lipid content in summer 9.21±0.02 and 10.71±0.04 in 1-3Kg weight group and 12.89±0.02 and 13.84±0.03 in 3-5Kg weight group in both the sites respectively. Kidney recorded lowest value of total lipid content as compared to liver and intestine in all the seasons both in 1-3 and 3-5 kg weight groups as compared to liver and Intestine. The results also show that the season, size, age, sex, reproductive cycle as well as breeding season directly influence the proximate composition of fish depends. All biochemical parameters differ significantly (P<0.001) among Farmed and Wild both in 1-3 and 3-5 Kg weight groups, under investigation.
