The parameters of length-weight relationship of Otolithes ruber were estimated and corresponding equation was W=0.0294 L2.6970 for male and W=0.0316 L2.6884 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=0.0268L2.7017. The fluctuation in the relative condition factor (k ) values with respect to size in- n dicated that condition of fish showed that an increase trend in size of fish. The k values steadily increased up to about n 190-210 mm and thereafter showed fluctuation. The seasonal fluctuation in the relative condition factor of both the sexes was attributed to the sexual maturity cycle and food intake.
