Caption

RNA sequencing was used to determine changes in gene expression after oil exposure in mahi-mahi. The genetic changes seen manifest itself in a variety of ways, but some of the most pronounced are the development of the eye and cardiac impairments including reduced heart rate and pericardial edema which is visible in this video. The fish in this clip are 48 hours post fertilization (hpf) and the oil exposed fish has been exposed to a 2.1%HEWAF slick oil preparation (8.9 μg/L ΣPAHs).
