Executive Summary

The ISRP and IEAB reviewed two reports pertaining to the Select Area Fisheries Enhancement Project (SAFE). The ISRP evaluation focuses on “Select Area Fishery Evaluation Project, October 1993 to October 2005” (April 2006). The IEAB evaluation focuses on the economic analysis “Select Area Fishery Evaluation Project, Economic Analysis Study, Final Report” (November 2006).

ISRP

In general, the ISRP found that the SAFE project appears successful, providing high and relatively stable harvest rates with minimal impacts on non-target and listed stocks, especially those above Bonneville Dam. The project is consistent with the Northwest Power and Conservation Council’s Fish and Wildlife Program and the Bi-State Lower Columbia River and Columbia River Estuary Subbasin Plan. Survival rates of SAFE fish are generally about equal to or better than those achieved at lower Columbia River hatcheries. Harvest of SAFE fish makes up a significant component of the lower Columbia River catch of salmon. Adaptive management has been a key component of the project. The fishery has been carefully monitored to assess catch and effects on non-target stocks and regulations have been adjusted when deleterious impacts have been observed or anticipated.

However, some concerns about the project and report remain. Discussion of methods in the report could have been more comprehensive and complete, and statistical analysis of the coded wire tag and experimental study data was entirely lacking. The report does not present convincing evidence that there is opportunity for expansion of production, and they do not explain why the maximum production goal of 11,300,000 smolts was chosen. Methods for estimation of harvest rates and “impact rate” of select area fisheries on non-target and listed stocks should be discussed more clearly. Because the estimate of harvested fish is not verified, concerns are raised about the validity of the income generated from the fishery. A critical unknown of the SAFE program is potential impacts of large releases of SAFE fish in the future on other populations during periods of prolonged poor ocean conditions.

Consequently, the ISRP recommends:

Extreme caution should be taken in expanding production in future years. Ultimately, continuous monitoring is essential to determine harvest and survival rates, impacts on non-target fish stocks, and stray rates of SAFE fish as production increases. The assumption should not be made that because impacts appear nominal with the present scale of production, they will continue to be so as the fishery expands.

Full rationale supporting the ISRP’s recommendations is provided in the main body of the report.

IEAB

The economic analysis is generally responsive to the economic issues raised in the 2005 ISRP/IEAB review, although the report presents some problems with regard to documentation, detail, and clarity of analysis that make it difficult to review.

The two general questions addressed by the economic analysis are whether changes to the SAFE project would generate net economic benefits and whether the SAFE project is a cost-effective approach to a mitigation fishery in the lower Columbia River.

Does the SAFE project generate economic benefits?
