Patterns of reproduction and spawning of the Scomberomorus commerson in the coastal waters of Iran.

摘要

Patterns of reproduction and spawning were studied for the king fish (Scomberomorus commerson) in the Persian Gulf (Hormozgan province). During one year of sampling, 599 fish were collected from different landing sites along the Persian Gulf. Analysis of the reproductive stages and gonadosomatic index revealed a single yearly reproductive cycle beginning in March and ending with a single spawning period in August-September. The mean length at first maturity (Lm 50%) for females was 75 cm. The sex ratio was M/F=0.97 in the samples.
