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 of the research assessing the effects of the spill has focused on early life stages of fish, studies examining whole‐animal physiological responses of adult marine fish species are lacking. Using swim chamber respirometry, the present study demonstrates that acute exposure to a sublethal concentration of the water accommodated… 
Impacts of Deepwater Horizon crude oil on mahi-mahi (Coryphaena hippurus) heart cell function.
This study is the first to measure cellular contractility in oil-exposed cardiomyocytes from a pelagic fish, contributing to previously observed impairments to heart function and whole-animal exercise performance in mahi and underscoring the advantages of using an integrative approach in examining mechanisms of oil-induced cardiotoxicity in marine fish.
Exposure to crude oil from the Deepwater Horizon oil spill impairs oil avoidance behavior without affecting olfactory physiology in juvenile mahi-mahi (Coryphaena hippurus).
Results show that a brief oil exposure impairs the ability of mahi-mahi to avoid oil and suggests that this alteration likely results from injury to higher order central nervous system processing rather than impaired olfactory physiology.
Oil exposure impairs predator–prey dynamics in larval red drum (Sciaenops ocellatus)
Oil exposure caused a dose-dependent increase in time spent in the exposed area of the arena, with an average three-fold increase at the highest dose, suggesting increased risk-taking and prey-capture ability did not appear to be related to cardiorespiratory or swimming impairments.
Prior exposure to weathered oil influences foraging of an ecologically important saltmarsh resident fish
The study findings highlight the sublethal effects of prior oil exposure on foraging abilities of ecologically valuable Gulf killifish at realistic oil exposure levels, suggesting that important trophic transfers of energy to off-marsh systems may have been impacted by shoreline oiling at highly localized scales.


Acute embryonic or juvenile exposure to Deepwater Horizon crude oil impairs the swimming performance of mahi-mahi (Coryphaena hippurus).
It is shown that brief exposure of a water-accommodated fraction of oil from the spill to mahi-mahi as juveniles, or as embryos/larvae that were then raised to juvenile stage, reduces their swimming performance.
Ultraviolet Radiation Enhances the Toxicity of Deepwater Horizon Oil to Mahi-mahi (Coryphaena hippurus) Embryos.
It is reported that coexposure to natural sunlight and WAF significantly reduced percent hatch in mahi-mahi embryos, suggesting that laboratory toxicity tests that do not include UV may underestimate the toxicity of oil spills to early lifestage fish species.
Effects of exposure to the water‐soluble fraction of crude oil on the swimming performance and the metabolic and ionic recovery postexercise in Pacific herring (Clupea pallasi)
It is shown that hydrocarbon exposure can reduce the swimming ability of fish and their ability to recover from exhaustive exercise and several key postexercise parameters, including plasma cortisol, lactate, and muscle glycogen, were significantly altered by exposure to WSE.
Delayed effects on growth and marine survival of pink salmon Oncorhynchus gorbuscha after exposure to crude oil during embryonic development
Delayed effects on growth and survival support claims of delayed effects in pink salmon after the 'Exxon Valdez' oil spill, and indicate the potential for population-level effects resulting from embryonic exposure to oil.

Sensitivity of fish embryos to weathered crude oil: Part II. Increased mortality of pink salmon (Oncorhynchus gorbuscha) embryos incubating downstream from weathered Exxon valdez crude oil
We incubated pink salmon embryos under three exposure conditions, direct contact with oil‐coated gravel, effluent from oil‐coated gravel, and direct contact with gravel coated with very weathered oil
Distribution and Habitat Associations of Billfish and Swordfish Larvae across Mesoscale Features in the Gulf of Mexico
Habitat suitability of all four species was strongly linked to physicochemical attributes of the water masses they inhabited, and observed abundance was higher in slope waters with lower sea surface temperature and higher salinity.
Biology of the dolphinfish ( Coryphaena hippurus ) in the western central Atlantic: a review
Marked differences in some biological characteristics and in the frequency of IDH-2 alleles between dolphinfish from the southeastern USA and the Caribbean suggest a relatively complex stock structure for this species, which needs further investigation to improve the information base for development of management strategies across this region.
