This study presents the weight-length relationship and spawning period of the Omani Indian Oil
sardine Sardinella longiceps (Valenciennes 1847) which inhabits the near shore zone along the Omani coast.
A total of 1744 specimens were collected between January 1997 to February 1998 from Al-Seeb; a suburban
area situated by the sea in Muscat, Oman. Samples were obtained on a monthly basis from beach seine and
gillnet catches. The female to male sex ratio was obtained to be 0.6. The monthly variation in the
gonadosomatic indexes indicates that the fish spawn in March; August and February. The overall length-weight
relationships were found to be W = (8.13×10-6)×L3; W = (9.07×10-6)×L3; and for the W = (8.43×10-6)×L3
combined sexes; female; and male; respectively. The length at which 50% of the sardines were estimated to be
172 mm (43.48 g) for the combined sexes; 169 mm (41.3 kg) for females; and 167 mm (39.74 g) for males.
Key words: Gonadosomatic indeces, Oman, relative weight, sardinella longiceps, sex ratios, weight-length relationships,
