Coded Wire Tag Program Review

Under the Pacific Salmon Treaty, fishing regimes for chinook and coho salmon are based on constraining stock, age, and fishery specific mortality rates for selected naturally spawning populations. Data to permit direct estimation of fishing mortality rates on individual populations of these species currently depend on the coded-wire tag program. Concern is now growing over the statistical reliability of this program and the ability to maintain the information expected from it.

A workshop was held on June 7-10, 2004 in Seattle, Washington to examine limitations of the CWT program and to evaluate the capacity of alternative technologies to provide data to improve assessment of chinook and coho salmon.
