Florida supports diverse marine and freshwater fisheries and a significant aquaculture industry with a combined economic impact of approximately 15 billion US$. We begin by describing the characteristics
Key Messages• Sea level rise, more frequent severe storms, coastal habitat loss associated with both factors, changes in nutrient dynamics, and ocean acidification are likely to impact the productivity of Florida's marine fisheries. Some of these factors will also affect fisheries access.• Florida's freshwater fisheries will be impacted by increased hydrological variability, increased temperatures, and more frequent severe storms. Shallow lakes may respond by switching from a clear to a turbid, phytoplankton-dominated state that provides poor sport fishing. Greater hydrological variability will also exacerbate fishing access issues.• Among the aquaculture sectors, shellfish aquaculture is particularly sensitive to multiple drivers including sea level rise, coastal habitat loss, increased frequency of harmful algal blooms and ocean acidification. Ornamental fish culture and other forms of intensive aquaculture under controlled conditions will be relatively insensitive to climate change.• Key adaptation options for marine fisheries include switching of species, locations and fishing methods, while adapting catch limits to changes in productivity. In freshwater fisheries, on the other hand, water and habitat management will be key to adaptation. Change in farming methods will be important in aquaculture, along with species and location changes, particularly in the shellfish industry. Aquaculture for fisheries enhancement and ecological restoration can aid adaptation in both marine and freshwater fisheries. Adaptation will benefit from awareness of drivers and impact pathways, monitoring of a broad suite of impact indicators, and adaptive decision-making. 428 • KAI LORENZEN ET AL.
