Reef fishes that form fish spawning aggregations (FSAs), such as grouper and snapper, are threatened not only due to overfishing, but also by environmental stressors. While management strategies and measures may currently be effective at reducing the impacts of fishing pressure on FSAs, they may not remain effective in the future if FSA locations change due to warming or other environmental stressors. The Gulf of America, as home to several FSAs, is an important region for fisheries, and needs to be managed to minimize overexploitation of FSAs. To be successful at these goals, management needs to consider climate stressors, as these may result in declines or shifts in the location or timing of FSA formation. To gain a better understanding of environmental change on FSAs, projections for Nassau Grouper (Epinephelus striatus) spawning habitat suitability under various climate scenarios were performed. Additionally, work is underway investigating climate change impacts on FSAs in marine sanctuaries. Finally, we will soon begin modeling multi-species FSAs in the Gulf. First, a database of known FSAs will be assembled; then ecological niche modeling and larval dispersal projections for future trends under environmental change will be made. This will contribute to an understanding of how FSAs may be impacted by environmental change, and will provide deliverables such as FSA databases including population connectivity and identification of essential fish habitat. Additionally, future projections would provide insight into how existing fish habitats may decline or shift, as well as how environmental variability may alter connectivity. These products will then be conveyed to end users via workshops and advisory meetings, where they will be able to shift the way we monitor, assess and manage FSAs in the Gulf.
