The Deepwater Horizon incident likely resulted in exposure of commercially and ecologically important fish species to crude oil during the sensitive early life stages. We show that brief a water-accommodated fraction from spill mahi-mahi as juveniles, or embryos/larvae were then raised for ∼25 days reduces their swimming performance. These physiological deficits, attributable polycyclic aromatic hydrocarbons (PAHs), occurred at environmentally realistic concentrations. Specifically, 48 h 1.2...
The temporal and geographic attributes of the Deepwater Horizon incident in 2010 likely exposed pelagic game fish species, such as mahi-mahi, to crude oil. Although much research assessing effects spill has focused on early life stages fish, studies examining whole-animal physiological responses adult marine species are lacking. Using swim chamber respirometry, present study demonstrates that acute exposure a sublethal concentration water accommodated fraction oil results significant...
This paper describes advances in hatchery and grow-out technology of cobia (Rachycentron canadum, Linnaeus). In 2007, methods for capture, transport, acclimation, sampling, conditioned spawning, larval rearing, fingerling production, nursery, shipping have been perfected. Survival rates ranging from 17.5% to 35% were achieved egg size fingerlings (1.0 g) 2007 at the University Miami Experimental Fish Hatchery, with production approximately 20 000 per 12 L tank. Wild F1 broodstock spawn...
The 2010 Deepwater Horizon oil spill resulted in the accidental release of millions barrels crude into Gulf Mexico. Photoinduced toxicity following coexposure to ultraviolet (UV) radiation is one mechanism by which polycyclic aromatic hydrocarbons (PAHs) from spills may exert toxicity. Mahi-mahi (Coryphaena hippurus), an important fishery resource, have positively buoyant, transparent eggs. These characteristics result mahi-mahi embryos being at particular risk photoinduced goal this study...
Abstract The potential for marine aquaculture development in the United States is significant and recent factors have highlighted benefits of developing a shortened seafood supply chain to service domestic markets. Marine finfish particular hold tremendous as technological advancements, improvements production efficiencies, market forces aligned create opportunities growth within this sector industry. Olive flounder, Paralichthys olivaceus , also commonly known Japanese flounder or hirame...
Carnivorous marine finfish aquaculture has been the subject of intense criticism. Because process consumes more fish biomass in form fishmeal and oil than it produces, critics argue carnivorous causes a net loss living resources is unsustainable given continued expansion industry. While this "fish-in fish-out" critique factually correct, fails to capture all costs benefits aquaculture. Accepted theories on energy matter flow between trophic levels indicate that appropriates less ocean...
Year-round control of the spawning cycle cobia (Rachycentron canadum) has been established by using water temperature manipulation. To compare effectiveness this method to induce volitional in cobia, two 80 m3 recirculating aquaculture systems (RAS) were used. Temperatures one maturation tanks ('Mat 1') maintained between 27 and 29°C for 12 months 15.5-month study period. second tank 2') allowed fluctuate naturally throughout year ranged from 20 32°C. A total 101 events occurred spring 2008...
Windows of exposure to a weathered Deepwater Horizon oil sample (slick A) were examined for early life stage mahi-mahi (Coryphaena hippurus) determine whether there are developmental periods enhanced sensitivity during the course standard 96-h bioassay. Survival was assessed at 96 h following exposures ranging from 2 and targeting 3 general development, namely prehatch phase, period surrounding hatch, posthatch phase. In addition, different preparations used: high- low-energy water...
Identifying complex behaviors such as spawning and fine-scale activity is extremely challenging in highly migratory fish species becoming increasingly critical knowledge for fisheries management a warming ocean. Habitat use pathways have been extensively studied marine animals using pop-up satellite archival tags (PSATs), but high-frequency data collected on the reproductive swimming of fishes has limited by inability to remotely transmit these large datasets. Here, we present first...
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...
Growth rates of larval and juvenile bigeye scad Selar crumenophthalmus reared in captivity were studied. The results are presented, discussed, compared to wild S. other pelagic fish. a small carangid fish circumtropical distribution. Larvae modified mesocosm system sampled daily for growth. grew mean size 4.74 cm (Standard Length) 1.30 g by 45 days post hatch (dph). Larval length-at-age was best described the exponential equation Y = 1.966e0.0704t . For growth trials, 1940 stocked into four...
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...
