The small number of calico phase males obtained and you will observed in industry inside spawning 12 months may also be due to additional factors. This new Os color phase is generally stimulated because of the a top thickness of aggregating grownups. This would explain the high level percentage off Operating system boys about captive analysis (92%) to this certainly gathered males and folks observed in the newest community. The new captive study artificial a dense aggregation of breeding grownups, while anybody accumulated and seen in industry were not always inside aggregations. Regarding Nassau grouper, Epinephelus striatus, courtship colour habits and spawning craft is actually reduced intense within the reduced-occurrence populations than in large aggregations (Colin 1992).
