“…Scallop surveys were conducted at 12 study sites along the Florida Gulf Coast (Fig. 1) from 1992 to 2019 (see Arnold 2009, Granneman et al 2022), although not all sites were surveyed in all years. Surveys were conducted once annually from May to July at many of the sites (hereafter, “spring survey”).…”

“…Bay scallop spawning typically peaks in the fall (Sastry 1963, Geiger et al 2006, 2010) and after spawning significant mortality occurs (Barber & Blake 1983). Florida bay scallops live associated with seagrass (Bologna & Heck 1999) and macroalgae (Granneman et al 2022) in shallow nearshore waters and estuaries (Fay et al 1983) that are dynamic marine systems subject to multiple stressors, including climate change, habitat loss, eutrophication, and hypoxia. Although bay scallops respond quickly to changes in the marine environment because they have rapid growth rates and rapid rates of turnover at the population level (Barber & Blake 1983, Bologna 1998, Geiger et al 2020), the environmental drivers of bay scallop abundance in these dynamic systems along the Florida Gulf Coast are not well understood.…”

The Florida bay scallop (Argopecten irradians concentricus Say, 1822) is a relatively short-lived species that resides in dynamic marine systems and is subject to multiple stressors, although the environmental drivers of bay scallop abundance along the Florida Gulf Coast are not well understood. The use of an ecosystem approach to fisheries management may be particularly relevant for short-lived species that are highly susceptible to environmental changes, but this approach requires an understanding of how environmental variables, such as salinity and temperature, may influence bay scallops throughout their range. This study was designed to identify the relationships between environmental variables and bay scallop abundance and to evaluate the relative effect of these relationships. Scallop surveys conducted in the spring and fall along the Florida Gulf Coast from 1992 to 2019 were compared with seasonal water quality parameters, streamflow discharge, precipitation, wind speed, and climate indices. The size and spawning success of the fall scallop population were negatively affected by relatively high Karenia brevis counts, low dissolved oxygen, and low phosphorus availability. During the period of early postsettlement growth in the winter, scallops were negatively impacted by salinities outside the range of 22–27 due to increased rainfall and low nitrogen availability. Finally, the factors that negatively affected juvenile scallop growth and survival in the spring included increased rainfall and wind speed resulting in relatively high turbidity and comparatively low chlorophyll a.
