PROXIMATE COMPOSITION OF HEAD AND SCALES IN WILD AND FARMED Ctenopharyngodon idella UNDER DIFFERENT WEIGHT CATEGORIES

Abstract

Proximate composition of head and scales from wild and farmed Ctenopharyngodon idella of three different weight categories W1 (601-900gm), W2 (901-1200gm) and W3 (1201-1500) was studied. An increase in protein and lipid contents was noted with an increase in weight of fish but moisture contents decreased with increasing fish weight. Significant (P<0.05) differences were found among three weight categories for moisture, protein, lipids, ash and carbohydrates. Maximum moisture was noted as 54.80% in head of wild C. idella of weight category W1. Maximum protein (21.86%) and lipid (19.39%) percentages were noted in head of farmed fish of weight category W3. Maximum ash contents were observed as 6.66% in head of wild C. idella of weight category W2. Maximum carbohydrates (0.61%) were observed in head of farmed fish of W2 weight category. The wild C. idella of weight category W1 showed maximum moisture (52.07%) and maximum protein content (23.14%) in case of weight category W2. Maximum lipids (0.74%) and maximum ash content (25.77%) were recorded in framed C. idella of W2 and W1 weight categories, respectively.
