Proximate Analysis of Grass Carp (Ctenopharyngodon idella) from Southern Punjab, Pakistan

Proximate analysis implies percent composition of moisture, protein, lipids and carbohydrates. The purpose of this study was to affirm the proximate composition and nutritious status of Ctenopharyngodon idella. Standardized methods were used to determine the proximate composition of 72 samples. On wet weight basis, mean percentage for water was 80.76 %, ash 3.40 %, 4.31 % for fat and 11.53 % for protein in C. idella. Percent water contents showed inverse relationship with % protein (dry and wet body weight), % ash and % organic contents (wet body weight). Wet body weight (W) showed negative correlation (P 0.001) with percent water, percent fat (dry and wet body weight) and positive correlation with percent protein, ash (wet and dry weight). Total length (TL) showed positive correlation with water, fat, ash, protein and organic content (dry and wet body weight). Condition factor (K) was found significantly correlated (P 0.05) only with % water and % ash. Multiple correlation among W, TL, K and different body content showed significant correlations. Results indicated that Grass Carp is a rich source of protein (58.35%) in dry body weight, additionally, the pioneer reference to the proximate analysis for this species from farming system of southern Punjab, Pakistan is provided.
