Combined effects of oil exposure, temperature and UV-radiation on buoyancy and oxygen consumption of embryonic mahi-mahi, Coryphaena hippurus

The timing and location of the 2010 Deepwater Horizon (DWH) incident within the Gulf of Mexico pelagic zone likely resulted in exposure of commercially and ecologically important fish species, such as mahi-mahi (Coryphaena hippurus) during the sensitive early life stages. A 24-channel optical fluorescence oxygen sensing system for high through-put respiration measurements was used to investigate the individual and combined effects of oil exposure, temperature and UV-exposure on oxygen consumption rates in embryonic mahi-mahi. Images included in the dataset were used to calculate yolk sac depletion by calculating the number of pixels in both the yolk sac and chorion area of embryos. Raw data on embryo buoyancy (measured on a range of -1 to +1) and hatch rate data are also provided.
