Studies on length-weight and length-length relationships of four freshwater fishes collected from river Ganga

Abstract

This study describes length-weight and length-length relationships of four species (Labeo bata, Channa punctata, Ompok pabda and Mastacembelus armatus) collected from river Ganga. A total of 856 specimens were examined for the study. Length-Weight Relationship (LWR) indicated isometric pattern of growth for L. bata, positive allometric growth for O. pabda and C. punctata while negative allometric growth for M. armatus. Length-length relationships (LLR) for all the four species were highly significant (R2>0.9, p<0.001). For two species length-weight and length-length relationships were not available on FishBase. © 2012 Academic Journals Inc.
