The length-weight relationship in Trichiurus lepturus was found to be W = 0.000012 L2.9925 (r =0.698) in males, W = 0.000013 L2.9329 (r=0.878) in females and W = 0.000013 L3.0348 (r=0.746) for sexes pooled data. In Lepturacanthus savala it was W = 0.000011 L 2.8948 (r = 0.856) in males, W = 0.000014L 2.5170 (r = 0.825) in females and W = 0.000013 L 2.7146 (r = 0.815) for sexes pooled. Analysis of covariance revealed no significant difference in growth in relation to length between the sexes in T. lepturus, whereas in L. savala it was significant between the sexes.
