Abstract
The length-weight relationship proved no significant difference between sexes, and the relationship can be described by a single equation: Log W = -5.4870 + 3.2069 Log L. The relative condition factor indicated peak in February for males and April for females. The size at first maturity has been estimated at 189 mm. Maturity studies indicate prolonged spawning season i.e. November-May. This fish is a pelagic carnivore feeding mainly on sergestids (Acetes spp.) followed by fish of Apogon spp., Myctophum spp. and molluscs.
