Abstract

The reproductive pattern of longnose trevally (Carangoides chrysophrys) in the Arabian Sea, off the coast of Oman, is described. Samples were collected on a monthly base between April 2005 and September 2006 from two landing sites (ALlakbi and Raysuot). A single peak of the gonadosomatic index (GSI) started from September and ended in February signalling the spawning period. Values of the relative condition factor (K n) were fairly constant throughout the year for both males and females and no significantly difference was found in the average K n values between males and females during sampling period. Male and female lengths-at 50% maturity were 46.90 and 42.08 cm, respectively and were significantly different. This study thus increases our understanding of the reproductive biology of an important commercial and artisanal fish species in one of its major distribution areas.
