“…A 120‐m transect was selected because 120 m was the maximum distance from shore where depths were consistently shallow enough to permit sampling with seine nets. Our seining technique followed Purtlebaugh & Rogers (2007), whereby nets are hauled parallel to shore, against the current (or wind if stronger) and pursed such that a standardized area of 142 m 2 is sampled with each haul. At least two seine samples were collected simultaneously and the sequence at which each distance was sampled was chosen randomly.…”

Whereas diel fish migration between mangrove and seagrass habitats has been recognized for decades, quantitative studies have focused mainly on diurnal patterns of fish distribution and abundance. In general, previous studies have shown that fish abundances decline with increasing distance from mangroves; however, evidence for such a pattern at night, when many fishes are actively feeding, is scarce. The present study is the first to report nocturnal fish abundances along a continuous distance gradient from mangroves across adjacent seagrass habitat (0–120 m). Here, we used nocturnal seine sampling to test the null hypothesis (based on diurnal studies and limited nocturnal work) that fish abundance would decrease with increasing distance from shoreline. We focused on species and life‐stage‐specific abundance patterns of Lutjanus griseus, Sphyraena barracuda, Archosargus rhomboidalis, and Haemulon sciurus. Results indicated that assemblage composition and structure differed significantly by season, likely influenced by temperature. However, within each season, the fish habitat use pattern at both the assemblage and species‐specific level generally failed to support our working null hypothesis. Species‐specific analyses revealed that, for most species and life‐stages examined, nocturnal abundance either did not change with distance or increased with distance from the mangrove‐seagrass ecotone. Our results suggest that analyses where taxa are grouped to report overall patterns may have the potential to overlook significant species‐ and stage‐specific variation. For fishes known to make nocturnal migrations, we recommend nocturnal sampling to determine habitat utilization patterns, especially when inferring nursery value of multiple habitats or when estimating fish production.

“…Although the spatial and temporal limitations of the red tide data precluded inclusion into these indices of abundance, the spawning and recruitment periods for these three species all overlapped with the months of the highest red tide concentrations in Tampa Bay (May through December; Hu et al 2006). Juvenile C. nebulosus and C. arenarius are typically found in the Tampa Bay estuary from April through October, following an active spawning period ranging from March to October (McMichael and Peters 1989;Purtlebaugh and Rogers 2007). Recruitment of juvenile S. ocellatus begins in September and continues through February, with a peak occurring in October and November (Reagan 1985;Peters and McMichael 1987).…”

An unusually persistent red tide event caused by the ichthyotoxic dinoflagellate Karenia brevis occurred along the southwest Florida coast in 2005. Extensive fish kills led to concerns regarding the effect of red tide on fish populations and their subsequent recruitment. Community structure differences were analyzed for all small-and largebodied nekton species collected by fisheries-independent monitoring from 1996 through 2006. Indices of abundance of five economically important fish species were also calculated from this time period. A significant change in small-and large-bodied nekton community structure was apparent from summer 2005 through spring 2006. Declines in the annual recruitment of juvenile spotted seatrout (Cynoscion nebulosus), sand seatrout (Cynoscion arenarius), and red drum (Sciaenops ocellatus) were evident in 2005 and 2006. Species-specific subadult and adult abundances, however, were consistent with those of previous years. These community shifts and speciesspecific declines appear to be associated with the red tide event.

“…The only potential refugia for spawning adults would have been the low-salinity areas of upper Tampa Bay, comprising Zone 1 and Hillsborough Bay, a small bay to the east (Fig. 1) (Purtlebaugh & Rogers 2007). Historically, 1 of these 3 rivers, the Alafia (Fig.…”

“…Sand seatrout is a common sciaenid found in nearshore and estuarine waters of the Gulf of Mexico, targeted by recreational and commercial fishers (Purtlebaugh & Rogers 2007, Knapp & Purtlebaugh 2008. Spawning typically occurs from March through September (Shlossman & Chittenden 1981), with juveniles appearing in Tampa Bay, Florida (USA) from April through October (Purtlebaugh & Rogers 2007).…”

“…Spawning typically occurs from March through September (Shlossman & Chittenden 1981), with juveniles appearing in Tampa Bay, Florida (USA) from April through October (Purtlebaugh & Rogers 2007). Reproductive data from offshore collections around Louisiana and the Mississippi Delta indicate that spawning occurs in deep coastal waters (Sheridan et al 1984, Cowan & Shaw 1988, while in Texas spawning occurs in inshore Gulf waters and within the estuary (Shlossman & Chittenden 1981).…”

A passive acoustic survey using a random stratified design detected spawning aggregations of sand seatrout Cynoscion arenarius over 2 sequential spawning seasons (2004 and 2005) in Tampa Bay, Florida. In 2005, an intense Karenia brevis red tide at ichthyotoxic concentrations entered Tampa Bay 3 mo after the spawning season began. The bloom persisted through the end of the spawning season and was temporally associated with significant changes in the spatial distribution of spawning aggregations. Red tide was most prevalent and concentrated within the lower portion of Tampa Bay and extended to a lesser degree into the middle bay, but remained absent from the upper bay. While the percentage of sand seatrout aggregations in the middle bay zone did not significantly change from 2004 to 2005, aggregations in the non-impacted area of the upper bay increased, and the red tide-exposed lower bay experienced a significant and pronounced decline. These significant bay-wide changes in the sand seatrout spawning population coincided with the red tide event, most notably the considerable decline in the lower bay, but the broad spatial distribution of the aggregations in concert with certain reproductive and life history characteristics may buffer the population from long-term effects. Typically, it is difficult to assess the effect of disturbances on marine fish populations due to complexities in measuring the extent of the perturbation and the magnitude of the loss to the population. Our spatially explicit sampling design further enabled us to demonstrate the widespread effects of red tide on fisheries and provides an important tool for assessing the extent of loss to a spawning fish population.
