RESUMEN
Length-weight relationship and spawning season of Pickhandle barracuda, Sphyraena jello (C.) were studied for one year in Boushehr waters of the Persian Gulf. In the present study, 311 specimens were collected during November 2006 to October 2007. The samples composed of 151 (48.55%) male, 160 (51.45%) female; the sex ratio was M: F = 1 : 1.06. The b value ranged between 2.77 to 2.87 for male and female fishes, respectively. The relationship between body weight and length in total specimens was 2.82, indicating that this species show negative allometric growth. The peak spawning season of these fishes occur around spring, from April to June. The lowest Gonadosomatic Index recorded in August. The present study is the first record on length-weight relationship and spawning season of this species in the Persian Gulf region.
