The present study investigates the length-weight relationship of T. jarbua from east coast of India. A total of 210 individuals was collected from Parangipettai landings centre. Lenght-weight relationships were collected for all specimens sampled. The results obtained were: Log=0.4141+1.4229 log L for males and Log W=0.0977+1.6745 log L for females. The growth exponential (b) values were different for both sexes, an isometric growth (b=3) and a negative allowmetric pattern (b<3) were observed in males adfemales respectively.
