Impacts of Petroleum-Derived Pollutants on Fish Development: Figure 3b

A video from the 2017 review by Gary N. Cherr, Elise Fairbairn, and Andrew Whitehead, "Impacts of Petroleum-Derived Pollutants on Fish Development," from the Annual Review of Animal Biosciences.

Video of Pacific herring (Clupea pallasii) embryos exposed (from fertilization to 7 days postfertilization) to water passing over either (a) nonoiled gravel or (b) gravel coated with Alaska North Slope crude oil (1.5 g of oil per kg of gravel). The hearts are clearly different with respect to size and normal looping of the ventricle. Pericardial edema (blue circle) is obvious in the oil-exposed embryo. Tissue polycyclic aromatic hydrocarbons for the oil-exposed embryos were 3,000 ng/g wet weight (22). Video provided by J. Incardona.
