Title: Injury to Spawning Areas and an Evaluation of Spawning Escapement Enumeration of Pink Salmon in Prince William Sound, Alaska FS01

Project Year and Number: 1992: FS01

Other Fiscal Years and Numbers for this Project: 1991: FS01, 1990: FS01, 1989: FS01

Principal Investigator (PI): Stephen Fried (Alaska Department of Fish & Game)

Managing Agency: ADFG

Assisting Personnel: Brian Bue, Dan Sharp, Samuel Sharr

Research Location: Prince William Sound

Restoration Category: Damage Assessment

Injured Resources Addressed: Pink Salmon

Abstract: This project will complete the analysis of data from NRDA and restoration studies designed to improve the accuracy of wild pink salmon escapement estimates. Estimates of aerial survey bias and stream life from 1990 and 1991 studies represent a major advance in escapement estimation procedures. Results will dramatically improve past and future escapement estimates in Prince William Sound and will lead to more accurate and precise stock specific fisheries management. The commercial fishery in Prince William Sound is of major economic importance and also plays a major role in regulating populations of salmon in Prince William Sound. Wild stocks which were injured by the Exxon Valdez oil spill play a major role in the Prince William Sound ecosystem and are frequently intercepted in mixed stock fisheries dominated by hatchery fish. Accurate and timely estimates of spawning escapements are critical for biologists who seek to ensure reproductive success for wild populations by manipulating fisheries.
