The GCMP used field assessments to understand how the leopard grouper (Mycteroperca rosacea) stock is related to pre-recruitment environments. The success of the leopard grouper is partially determined by the availability of nursery habitat the individual has as a juvenile. However, the ability of this habitat—rocky bottoms with Sargassum spp. beds—are largely impacted by climate conditions and decrease exponentially in availability with increases in the Multivariate El Nino Southern Oscillation Index. By defining indicating factors of leopard grouper populations, this study improved the predictability of leopard grouper availability. This has helped fine-tune the fishery’s management and increase the adaptability of the plan.
