Red snapper (Lutjanus campechanus), vermilion snapper (Rhomboplites aurorubens), scamp grouper (Mycteroperca phenax), and snowy grouper (Hyporthodus niveatus) are important species both recreationally and commercially in the Southeast U.S. Atlantic coast (SA). Currently, there are regulations in place to minimize fishing pressure on these species with additional deep-water marine protected areas (MPAs) and spawning special management zones (sSMZs) that are meant to protect bottom habitat and fish within their boundaries. However, these protected areas are not the only habitats utilized. A comprehensive characterization of adult female distribution and spawning capable female distribution throughout the region would greatly improve our understanding of habitat utilization. Differences in these distributions would indicate spatial changes in habitat utilization and potential preferences with associated environmental variables. For this study, we utilized multiple timeseries of fishery-independent data ranging from 1990-2022 to determine the location of spawning hot spots and overall adult female distributions of all species from Cape Hatteras, NC to St. Lucie Inlet, FL. Boosted regression tree (BRT) analysis was used to explain complex relationships between predictor variables and fish presence/absence and abundance (CPUE). The final BRT models included combinations of latitude, longitude, bottom temperature, salinity, oxygen, and biota density as predictor variables and predicted the largest spawning hot spots based on different metrics. These results will fill knowledge gaps regarding the reproduction and distribution of adult red and vermilion snapper and scamp and snowy grouper off the SA coast and could influence management decisions relating to the protection of the spawning areas of these valuable fisheries.
