Comparative study of seasonal variation in proximate composition and nutritional quality of farmed and wild Indian butter catfish (Ompok bimaculatus) in Tripura India

In the present study the biochemical compositions of farm raised pabda (FP) and wild pabda (WP) caught from Gomti River of Tripura, India was analyzed to record their proximate compositions in terms of environmental and seasonal variations. Farm raised pabda (FP) and WP with similar length and weight were collected from College of Fisheries Tripura. The different biochemical, macro and micro mineral contents were examined monthly samples from July-2012 to February-2013. The parameters were recorded namely moisture, ash and protein content. The results showed that there was no significant differences (p>0.05) in FP and WP, except in lipid content which was higher in FP (6.73-7.32%) than in WP (5.35-7.26%). The seasonal variation in proximate composition was recorded as there was gradually increase in the protein and lipid content from the month July to February whereas the moisture content was decreased at same time. Similarly the mineral concentration showed the higher in WP compared to FP except Iron (Fe) content. Iron content significantly higher (p
