Abstract: This project is a component of the Sound Ecosystem Assessment (SEA) program, a multi-disciplinary effort to acquire an ecosystem level understanding of the marine and freshwater processes that interact to constrain levels of fish, marine bird, and marine mammal production in Prince William Sound (PWS). Pink salmon are an important food source for fish, birds, and mammals, and provide a pathway for the transfer of nutrients accumulated from high seas marine areas to near shore and terrestrial ecosystems. Pink salmon are vital to the economy of PWS communities. Evidence indicating that the EVOS was partially responsible for weak pink salmon return to PWS is growing. PWS pink salmon embryos incubating in oiled areas have shown significantly higher mortalities than those incubating in unoiled areas. Fry and juvenile salmon rearing in oiled areas exhibit reduced growth and survival. To sustain production from wild populations, managers must ensure that adequate numbers of wild fish return to spawning streams. To enable fisheries managers to regulate the harvest of injured wild stocks, percentages of the pink salmon harvests will be scanned for coded-wire tags. Estimates of the contribution of hatchery fish to the PWS pink salmon population will be made to estimate wild stock total returns and survival.
