An analysis of 15 specimens of the oceanic squid Sthenoteuthis oualaniensis caught by hooks and lines from the Arabian Sea showed that the growth pattern was isometric with the length-weight relationship W = 0.0276 L^3.11. The von Bertalanffy growth parameters estimated were L_∞ = 49.1 cm; K = 0.83 yr^-1 and t_o, -0.06 yr. Other population parameters such as optimum length for exploitation, length at maturity and natural mortality rate were also estimated. Relative fecundity was 125 no. /g body weight. The egg diameter ranged from 0.7 to 0.9 mm. The scope for exploitation of the oceanic squid is discussed.
