Abstract
von Bertalanffy's growth equation was used to describe growth of Scoliodon laticaudus Muller and Henle. The L , K and t^ values estimated were 715 mm, 0.3580, and 0.590 for females and 676 mm° 0.4046 and 0.590 for males respectively. Females grow larger and live longer than males. The overall sex ratio was 1 : 1.31, the females predominating, more so from 551-600 mm size group onwards. The average estimated annual catch was 14.4 tonnes at the existing F value of 0.73.
