  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.

  This study presents preliminary results on the early development and growth of the sea cucumber Holothuria leucospilota in the Bostane equatic ecosystem on the coast of Persian Gulf. For this purpose, spawning was induced by thermal stimulation after fertilization, embryos were incubated under optimal conditions (salinity between 38-40 and temperature 33 degrees) until reached the late uricholaria stage. In order to study the developmental stages and the timing of each stage including cleavage, morula, blastula, gastrula, early auricularia, auricularia, late auricularia the embryos were studied by light microscopic studies. Observations showed that after 120 h from fertilization time, the embryos developed to late auricularia stage.
