Abstract:

This dataset contains data for effects of oil from surface (OFS) from the Deepwater Horizon oil spill (HEWAF) exposure on various mesocosm experiments. Acute toxicity to larval coral reef fishes was measured as survival rate after 24 hrs. Latent toxicity to larval coral reef fishes was measured as survival rate after 7 days. Settlement patterns of larval reef fishes were measured as settlement choice on low, medium or high complexity coral in a mesocosm. Predator avoidance by larval coral reef fishes was measured as survival rate in the mesocosm 4 hrs after predator release. Boldness of larval coral reef fishes was measured as the tendency to explore new territory in open areas away from shelter (thigmotaxis). Fast start escape performance of larval coral reef fishes was measured using high speed cameras and a mechanical stimulus. Growth rate of larval reef fishes was measured over 7 days in mesocosm with unlimited food and no predators.

Data Parameters and Units:

HEWAF=high energy water accommodated fractions; Temperature (Centigrades); Time (24hr); Exposure/Concentration (0%/control, 5%/Mid or 10%/High HEWAF); Species (Ambo= Pomacentrus amboinensis, Atri=Chromis atripectoralis, Banka=P. bankanensis, Mol=P. molluccensis, Chry=P. chrysurus, Let=Lethrinidae sp.); Habitat complexity (Good=>75% live coral, Medium=15-30% live coral, Low=0% live coral, Sand=no coral or shelter); Weight (gram); Trial 1,2,3 = order of trials individuals underwent; DIST = distance travelled during the escape (cm); SPEED = average swimming speed during escape (mm/s). MAX SPEED = maximum speed reached during escape (mm/s).
