Comparative analysis of some biochemical parameters and length weight relationship of Schizothorax niger and Oncorhynchus mykiss from Kashmir, India

Abstract

The study was aimed to investigate the biochemical composition of S. niger and O. mykiss. The biochemical parameters studied were total protein and total glucose estimated from the digestive tract of the two species. The length weight relationship was also estimated for both the fishes. Descriptive statistics of S. niger for protein showed the maximum value of 12.09 (g/dl) and minimum value of 0.11 (g/dl). For glucose, the maximum value was 96.91 (mg/dl) and the minimum value of 35.5 (mg/dl). Descriptive statistics of trout for the protein showed the maximum value of 43.18 (g/dl) and minimum value of 21.40 (g/dl) while for glucose, the maximum value of 151.36 (mg/dl) and minimum value of 58.85 (mg/dl) was estimated. The length-weight was established logarithmically as: S. niger: Log W = -3.344 + 2.293 Log L (R 2 = 0.733) and for O. mykiss: Log W = -3.491 + 2.351 Log L (R 2 = 0.939).
