Length-weight and Length-length relations of four fish species from the Chilika Lake, East coast of India

Abstract

This study reports the length–weight relationship (LWR) and length-length relationship (LLR) estimated for four fish species inhabiting in Chilika Lake, India. Total 504 specimens were sampled from mono-filament gill nets (mesh size 12 mm, 22–24 mm, 34–38 mm, 42 mm) during January 2015 to December 2015. The estimated b values from LWR ranged between 2.79 (T. biaculeatus) to 3.29 (C. praeustus). In all species, the relationships between length-weight and length-length were highly correlated (p < .05). The study provides first world reports on LWRs and LLRs for all the 4 studied species.
