    • Abstract


      The length-weight relationship was computed independently for males and females ofMacrognathus aculeatus. The analysis of covariance revealed no significant difference (p=0·05) between the length-weight relationship of males and females. Hence, a common logarithmic equation (log W=−5·6934+3·1234 log L) was fitted for the species. The regression coefficient of logarithm of weight on logarithm of length was found to depart significantly (p=0·05) from the cubic value.
