Project Year and Number: 1994: 94137

Other Fiscal Years and Numbers for this Project: 1995: 95137, 1993: 93068

Principal Investigator (PI): Samuel Sharr, Alaska Department of Fish & Game

Research Location: Prince William Sound

Restoration Category: General Restoration

Injured Resources Addressed: Sockeye Salmon

Abstract: Strong evidence indicates that the spawning success and early marine survival of chum and pink salmon in Prince William Sound (PWS) was adversely affected by the EVOS. Emerging fry and smolt of all salmon species throughout PWS migrated through and reared in areas contaminated by oil. Salmon stocks impacted by the EVOS are heavily exploited in commercial, sport, and subsistence fisheries and their restoration may be realized through management practices designed to reduce exploitation on impacted stocks.

This project is designed to provide accurate estimates of salmon stocks in PWS, and will enable fisheries managers to identify stocks which are experiencing escapement shortfalls and to identify areas where exploitation of depleted wild stocks can be minimized and still permit the harvest of surplus hatchery returns.

By sampling sockeye, chum, chinook and coho salmon catches and hatchery brood stock in PWS for coded wire tags, estimates of hatchery and wild stock contributions to harvests can be made. Fisheries managers may use the data to lessen interceptions of wild fish in mixed stock fisheries.
