The Deepwater Horizon (DWH) disaster released 3.19 million barrels of crude oil into the Gulf Mexico (GOM) in 2010, overlapping habitat pelagic fish populations. Using mahi-mahi (Coryphaena hippurus)─a highly migratory marine teleost present GOM during spill─as a model species, laboratory experiments demonstrate injuries to physiology and behavior following exposure. However, more than decade postspill, impacts on wild populations remain unknown. To address this gap, we exposed or control...
Abstract The red snapper ( Lutjanus campechanus ) has one of the most valued fisheries in southeastern United States and been largely studied for its aquaculture potential with varied results that revealed production challenges. This study focused on addressing challenges larval rearing juvenile this species. Broodstock fish were acclimated a 60 m 3 tank equipped recirculating system (RAS) temperature control. After 1 year captivity, volitionally spawned trials conducted replicated...
Pop-up satellite archival tags (PSATs) have been used to demonstrate habitat utilization and large-scale migrations of aquatic species are a critical tool manage highly migratory fish populations. Use PSATs has increased in recent years; however, few studies investigated the physiological behavioral effects carrying PSAT. To address this gap, young-adult mahi-mahi (Coryphaena hippurus; 25–35 cm fork length) were tagged with miniature assessed two-part experiment utilizing swim tunnel...
Progress towards the development of reliable hatchery technology for red snapper, Lutjanus campechanus, has been limited by inconsistent spawning and difficulties in larval rearing. We report on recent progress to improve this technology. A rearing trial assessing effects two different photoperiods was conducted at University Miami Experimental Hatchery (UMEH). Four 400-L tanks were subjected a photoperiod 16 h full spectrum light, four light 8 dim through 11 days post hatch (dph). S-strain...
Growth rates of a single cohort F1, captive-reared red snapper, Lutjanus campechanus, were determined through ontogeny using multi-model inference approach. Water temperature averaged 23.6 ± 0.13 °C based on the ambient conditions study location in Miami, Florida. length-at-age and weight-at-age best expressed von Bertalanffy model with equations Lt = 742.6 (1 – e0.001804(a-31.57)) Wt 84720 e-0.0005787(a+78.71))3.304, respectively. The length-weight relationship was by equation W 0.000003158...
