Abstract

Length-Weight relationships (LWR) provide basic information in fisheries biology. In the present study, LW relationships of ten species of coral reef associated fishes from Cuddalore, southeast coast of India was estimated. A total of 1263 individuals, belonging to eight families were measured and weighed. The exponent b of length-weight relationships ranged from 2.71 to 3.20. The LWR were significant (p<0.05) for these species. In terms of growth type, seven species had negative allometric (b<3), Epinephelus coioides had isometric (b=3) and Trachinocephelus myops and Upeneus vittatus had positive allometric (b>3) growth.
