Abstract

A study on the variation amongst the different populations of Labeo rohita on the basis of morphometric parameters was conducted. Samples were collected from fish farm having different weight groups of same age. Data regarding the morphogenetic parameters viz., body weight, fork length, total length and lengths of dorsal, caudal, anal, pectoral and pelvic fins of each individual were measured. Analysis of variance (ANOVA) for the different morphometric parameters of study was done using Minitab 16.0. The Pearson correlation analysis of the morphometric parameters was done by XLSTAT 2012 version 1.02. The results showed that positive correlation between the body weight, total length and average length of paired pectoral fins of L. rohita were non-significantly different (P> 0.05), anal fin length was significantly different (P<0.05), and all the remaining parameters were highly significantly different (P<0.01) among the population groups. The correlation of fish body weight and fork length was highly significant (p<0.001) and positive with all the parameters except with the caudal fin which was positively but non-significant in correlation with fork length (p = 161).
