Coded wire tag studies on Prince William Sound Salmon, 1992. Restoration study number 60a. Exxon Valdez oil spill state/federal natural resource damage assessment final report
Coded wire tags applied in 1991 at four hatcheries in Prince William Sound were recovered in the commercial catch of 1992 and used to provide inseason estimates of hatchery contributions. The estimates were used by fishery managers to target the numerically superior hatchery returns, and reduce the pressure upon oil-damaged wild stocks. A postseason analysis suggested that future inseason analyses be carried out using undecoded-tag data gathered from all sampled processors and that out of a commercial catch of 9.42 million pink salmon, 1.66 million fish were estimated to be of wild origin and 7.77 million of the hatchery origin. Tag recoveries from stream surveys in 1992 were also used to complete an estimation of oiling effects upon survival rates of adult wild pink salmon and no oiling effects were observed for 1992 returns.
