Proximate Body Composition Analysis of Two Commercially Important Members of Cyprinidae Family (Catla catla and Hypophthalmichthys molitrix) From Southern Punjab, Pakistan

Abstract

The present Study proposed to evaluate the body composition of Catla catla and Hypophthalmichthys molitrix collected from southern Punjab, Pakistan. Collected fishes samples werebrought to fisheries lab for further analysis. The mean value for water, fat, protein and ash as water is 75.1%; Ash in wet and dry weight 4.07 and 16.4; Fat in wet and dry weight 5.2 and 20.8; Protein content in wet and dry weight 15.62 and 62.66 respectively in C. catla. The value for mean and ranges for water, fat, protein and ash as water is 77.27%; Ash in wet and dry weight 4.20 and 5.21; Fat in wet and dry weight 1.55 and 6.10; Protein content in wet and dry weight 3.22 and 5.27 respectively in H. molitrix. Percent water showed highly significant correlation with all the body constituents except percent fat dry weight whichshowed non-significant correlation. All of the values showed a negative correlation with percent water except with percent ash wet and dry weight whichshowed positive correlation in C. catla. Body weight showed highly significant positive correaltion with all body constituents except the relationship with percent water, percent ash dry and wet weight in C. catla. A non-significant correlation with percent protein dry weight, a significant positive correlation with percent protein and fat wet; a least significant correlation with percent fat and ash dry weight while highly significant correlation with percent water in H. molitrix. Total length showed a highly significant negative correlation with log water, fat and protein content except ash whichshowed non-significant negative correlation in C. catla while highly significant negative correlation with log water, ash, fat and protein content in H. molitrix.
