The objective of this study was determine if weathered ANS crude oil would be phototoxic to juvenile pink salmon under conditions of short-term exposures to high levels of oil that may occur during an oil spill, and environmentally relevant levels of UV in natural waters. The results of this study indicate that pink salmon are at less risk from photoenhanced toxicity compared to early-life stages of several other Alaska species. Phototoxicity could occur under conditions of higher UV exposure, but additional research is not currently recommended as a high priority.
