Reproduction and spawning patterns of the Scomberomorus commerson in the Iranian coastal waters of the Persian Gulf & Oman Sea

  Reproduction and spawning patterns of the king fish (Scomberomorus commerson) were studied in the Persian Gulf (Hormozgan Province) and Oman Sea from Oct ۲۰۰۶ to Sep ۲۰۰۷. A total of ۱۱۲۰ fish was collected from different landing sites along the Iranian waters. Yearly analysis of the reproductive stages and gonadosomatic index showed a single reproductive cycle beginning in March and continued with a single spawning period from August to September. The mean length at first maturity (Lm ۵۰%) for females was ۸۳.۶ Cm. The sex ratio was M: F = ۰.۹۷:۱ which was not significantly (P > ۰.۰۵) different among samples (χ۲ test). Isometric growth for this species was approved.
