“…Sampling began in Tampa Bay (TB) and Charlotte Harbor (CH;, then expanded to the northern Indian River Lagoon (NIRL; 1990), Cedar Key (CK;1996), the southern IRL (SIRL; 1997), Apalachicola Bay (AP;1998), and Northeast Florida (JX;. The FIM program also expanded to offshore habitats in 2008 to address key limitations in available data on groundfish assemblages (Matheson et al, 2017;Christiansen et al, 2022b;see Pollack et al (submitted) in this issue for trawling surveys) as well as reef fish assemblages and their habitats (Keenan et al, 2022;Thompson et al, 2022;Switzer et al, 2023).…”

Development of Florida’s marine Fisheries-Independent Monitoring (FIM) program began in 1985, and it initiated long-term monitoring in Tampa Bay in 1989 with the purpose of providing timely fishery-independent data and analyses to fishery managers for the conservation and protection of the species that support Florida’s fisheries. Over time, the program expanded sampling in other Florida estuaries. Data from this monitoring program are integral to the assessment and management of numerous state and federally managed fishes, so long-term consistency is of paramount importance, but sampling design modifications have been necessary over time. This review presents three case studies in which the estuarine component of the FIM program was changed to address emerging data needs in management of Florida’s fishery resources, while maintaining standardization and consistency with long-term surveys statewide. In the first case study, survey changes increased the amount of data on juvenile common snook, Centropomus undecimalis, on the Gulf of Mexico and Atlantic coasts and improved indices of abundance, survival estimates, and age-length keys for state management purposes. In the second case study, the FIM program improved estimates of abundance of juvenile reef fishes by initiating a complementary survey that expanded FIM sampling to new regions of the Florida Gulf coast and targeted a unique habitat (polyhaline seagrass beds along estuarine shoal habitats) not previously sampled in the standard long-term survey. In the third case study, the FIM program addressed a data limitation for regional management of spotted seatrout, Cynoscion nebulosus, by initiating seasonal sampling in western Florida. In each case study, the standard long-term survey design was modified to include sampling of new and unique areas and habitats, providing valuable data on estuarine fish assemblages that support analyses at the broader, ecosystem level. Survey amendments were designed to maintain standardization and consistency, all with limited additional funding. The success of these survey modifications was the result of several key factors: mission-focused programmatic goals, geographically dispersed laboratories, standardized protocols, ongoing critical analysis of the data, grant award success, and high-level data management. Although each case study originated with a survey expansion, all were followed by survey reductions or streamlining, so expansion and reduction scenarios are presented in this review. Regardless of these modifications, the mission of the FIM program remains the same: to provide timely data and analysis for the use of fishery managers, including state and federal partners.

Understanding patterns in community structure in large marine ecosystems is necessary for advancing community- and ecosystem-based approaches to marine fisheries management. We analyzed data from a large-scale, fishery-independent video survey to quantify the structure of reef fish communities on offshore hard-bottom reef habitats in the northern Gulf of Mexico (nGOM). A novel aspect of this work is that all species visualized on videos were identified and enumerated over a 13-year period, which allowed for a comprehensive analysis of fish community structure. We observed a total of 243 fish species from 54 families and 14 orders. Species richness and biodiversity varied considerably across the nGOM and were highest in regions that harbor extensive coral reef habitat (south Florida, Louisiana-Texas shelf). Multivariate analyses identified 12 species assemblages, with important fishery species and species of concern (i.e. IUCN-listed) occurring in the largest identified assemblages. One assemblage composed mostly of large-bodied fishery species accounted for 45% by number and 89% by weight of all fish observed. Species assemblages were most strongly associated with depth, temperature, and substrate composition, with weaker associations with the amount of attached algae and vertical relief, while species richness was positively correlated with bottom water temperature. In general, large-scale bathymetric and hydrographic factors (e.g. depth, temperature) were more important than local topographic structure and biogenic habitat in structuring reef fish communities at the spatial scales (i.e.1000 km) considered here. Our results advance ecosystem-based approaches to fisheries management by providing a basis for incorporating multispecies spatial dynamics into the monitoring and assessment of hard-bottom reef fish communities in the nGOM.

Groupers (Epinephelidae) are ecologically important mesopredators that support valuable fisheries across the globe. Many groupers display slow growth and maturity, high longevity, ontogenetic habitat shifts, spawning-related migrations and aggregations, and protogynous hermaphroditism, which make them susceptible to overexploitation. In this review, I synthesize available information related to the management of grouper fisheries across the southeastern and Caribbean U.S. I highlight current management challenges, such as managing multispecies reef fish fisheries with growing recreational fishing effort. I discuss management interventions with limited success, such as establishing marine protected areas to improve the populations of groupers that display protogynous hermaphroditism. I also highlight management successes, such as recovering historically depleted grouper stocks, and ecosystem-based considerations in grouper stock assessments. I discuss how climate change and anthropogenic effects are expected to affect groupers. Lastly, I provide examples of stakeholder involvement in monitoring and management efforts directed at grouper stocks. The purposes of this review are to demonstrate the complexities of managing grouper fisheries and provide a road map for future research and conservation efforts into these economically and ecologically relevant fishes within and beyond the region.
