Reproductive biology of Rachycentron canadum in the Persian Gulf (Hormozgan Province waters)
We collected 478 specimens of Cobia, Rachycentron canadum, from Hormozgan province waters during October 2005 till September 2006, and studied reproductive parameters such as spawning season, sex ratio, maturity stages, fecundity and ova diameter. The maturity and spawning season were investigated through macroscopic and microscopic (ovarians histology) observation. Studying average Gonado-Somatic Index (GSI), the percent of maturity stages and ova diameter average changes revealed that the spawning occurred from July to the beginning of September.
