Assisting Personnel: Ron Heintz, Jeff Short

Research Location: Prince William Sound

Restoration Category: Research

Injured Resources Addressed: Pink Salmon

Abstract: Following the EVOS, elevated embryo mortalities were detected in populations of pink salmon inhabiting oiled streams in the Prince William Sound (PWS) area. Increased mortality rates have persisted three years after the EVOS, suggesting that genetic damage may have occurred, resulting in reduced reproductive capacity. A persistent decline of the wild pink salmon stocks could render present restoration efforts inadequate. This study will continue to monitor the recovery of pink salmon embryos and fry in the field, provide laboratory verification of field results, and test the hypothesis that exposure of pink salmon to a polluted incubation habitat will result in the functional sterilization of these animals at sexual maturity. The streams examined during the post-EVOS Natural Resource Damage Assessment will be used to sample egg deposition, pre-emergent fry, eggs, and fry. A laboratory will be used to expose fertilized eggs to oil in an environment mimicking actual environmental conditions. Embryos and fry from both the field and the laboratory will be examined for the presence of genetic aberrations.
