The length-weight relationship of Cociella crocodila was estimated and corresponding equation was W=0.0032 L3.2862 for male and W=0.003 L3.2498 for female. Analysis of covariance showed that there is no significant difference in length-weight relationship between the male and female. Hence, the pooled equation for both sexes was obtained at W=0.0031L3.2708. The fluctuation in the relative condition factor (K ) value with respect to size indicated n that condition of fish more or less showed an increasing trend with size of fish. The seasonal fluctuations in the relative condition factor of both the sexes could be attributed to the sexual cycle, food intake and environmental factor.
