Summary

This report completes the ISAB's three-part response to your request for a review of the draft performance standards and indicators attached to the Council's Artificial Production Review (APR).

With the Council's Fish and Wildlife program amendment process coinciding with the release of the draft FCRPS BiOP, the Governor's Plan, and the Federal Caucus All-H paper, important salmon and steelhead recovery planning is underway in the Columbia River basin.  These plans anticipate continued use of artificial production to provide fish for harvest and to help rebuild depressed wild stocks.  Consequently, the ISAB believes this letter of transmittal provides a timely and appropriate opportunity to summarize our review of the APR performance standards and indicators and to suggest that our integrated evaluation of the various regional plans could serve as a forum to continue to contribute to the region's hatchery reform efforts.

After completion of the APR, Council asked the ISAB to review the performance standards and indicators focusing on three questions:

  1. Are the draft performance standards and associated indicators the appropriate tools to periodically evaluate the effects of individual artificial production programs for the purpose of determining whether the principles, policies, and purposes in the Artificial Production Report (APR) are being fulfilled?
  2. Are the draft performance standards and associated indicators the appropriate tools to adequately evaluate the effects of the artificial production activities in the basin?
  3. If a performance standard, indicator or other means of measurement is not the most appropriate tool for this purpose, what other standard or indicator would you recommend?

The ISAB responded to that request by preparing three reports dealing with the following topics:

  1. Appropriateness of the Performance Standards and Indicators.
  2. Consistency of Artificial Production Policies and Implementation Strategies with the Multi-Species Framework Scientific Principles and the Scientific Review Team Guidelines.
  3. Development of an Appropriate Data System.

Our first report concluded that a set of indicators would be an appropriate tool to assess and evaluate individual artificial production programs (facilities) and artificial production activities in the basin. Establishing indicators consistent with the APR policies is an important early step in designing a monitoring program to assess and evaluate artificial production. This report also concluded that the performance standards and indicators attached to the APR were inappropriate and needed thorough revision.  We recommended developing a set of indicators that used measurable metrics with clear relationships to the APR policies, and ones that were organized hierarchically for subbasin, province, and basin components, while at the same time encompassing the five different purposes of artificial production.  Once that set of indicators was chosen, critical values, or norms, of those indicators could be established as performance standards.  Because empirical analysis is lacking for many of the possible indicators for the APR policies, performance standards initially would have to be selected based on ecological and evolutionary theory.  Adaptive management experimentation, in conjunction with a viable program of monitoring, could be used in the future to refine both the indicators and the performance standards.

One example of an indicator, proposed by NMFS to be used as its foundation for recovery evaluation, is lambda, the median annual rate of population growth.  Lambda is calculated from population census data and values above 1.10 indicate healthy populations, whereas values under 0.80 indicate populations in perilous condition.  Employing this metric as an indicator involves obtaining census data from monitoring, estimating lambda, and interpreting its value.  In the draft FCRPS BiOP, NMFS proposes standards for lambda in 5-year and 8-year hydrosystem reviews that would continue implementation of recovery actions or trigger reassessment of jeopardy conclusions.

In our second report we discussed our understanding of how the scientific principles in the Multi-Species Framework relate to artificial production and we commented on the implementation of the ten artificial production policies presented in the APR. The ISAB concluded first, that assessing and evaluating artificial production requires a comprehensive basin-wide tagging program, and second, that clear program objectives are needed to identify appropriate indicators.  Additionally, even though hatchery reform is a prominent feature of the APR, we noted a lack of specificity in identifying those practices to be reformed.  We believe that successful reform requires both identifying clear objectives and establishing an effective monitoring program to assess reform progress.

Our third report reiterates the recurring themes above: objectives for artificial production programs are needed for subbasins, provinces, and the entire basin.  Together with the APR policies, these objectives form the foundation for designing those indicators that would be used in a monitoring program to assess the Columbia River basin hatchery system.  Assessing the hatchery system requires collecting three types of information:

  1. Specific details of fish culture practices inside the hatchery.
  2. What happens to the hatchery produced fish after release.
  3. What effect the hatchery produced fish have on wild and other hatchery fish outside the hatchery.

Assessing how fish culture practices inside the hatchery (information type 1) affect what happens to hatchery produced fish after release (information type 2) is required to evaluate alternative fish rearing/release strategies and guide hatchery reform.  Assessing the effects of hatchery produced fish on wild and hatchery fish outside the hatchery is required to evaluate the success of supplementation and evaluate possible detrimental effects of mitigation and augmentation programs.

No organization is currently responsible for the design and implementation of a comprehensive monitoring program.  Because this monitoring should anticipate standardized data collections at hatcheries, within subbasins, the migration corridor, estuary, and ocean, the lack of a responsible organization needs to be addressed.

A monitoring program to assess artificial production needs an archiving system that provides stakeholders with access to the data.  There is no need to centralize the entire data storage and retrieval system.  Internet technology allows an effective system of web links between modular sites responsible for specific functions, such as data archiving or data access.  Data archiving functions should be modularized so there is one archiving center for each class of data.  At the current time there are not enough archiving centers, and important classes of data are not being compiled and archived in an accessible form.  The data access function should be modularized to serve specific data access needs, which can evolve with changing needs for analysis.

Because the recommendations provided in our three reports are intended to increase the likelihood of successful assessment, evaluation, and reform of the hatchery system, we have necessarily focused on perceived shortcomings.  We also want to acknowledge that the APR policies are generally consistent with the scientific principles in the foundation, and that we support them.  Our primary concern after reviewing the APR is that the implementation actions are not sufficient nor specific enough for the anticipated hatchery reforms to be realized. We believe the APR represents a beginning effort, not a completed task.

Hatchery technology was increasingly employed in the mid-1900's in an attempt to mitigate the effects of habitat elimination within the Columbia basin.  Regional decision-makers acknowledged they were using an unproven experimental technology, and some scientists urged more rigorous monitoring.  Based on the observation of continuing declines in returns of adult salmon to the basin coincident with increasing releases of hatchery smolts, we concur with the conclusions of the National Research Council and the Federal Review of Hatchery programs that mitigation was in fact unsuccessful.  Whether this lack of success was due to our inability to grow fish in captivity that could survive adequately in the wild, or whether it is due to habitat conditions being insufficient to support the numbers of fish produced is largely unknown.  Had the monitoring programs called for by scientists been implemented, at least a portion of this question could have been addressed now, and the controversy of employing hatchery technology resolved.

Planning efforts that are now underway anticipate continued use of hatchery technology,  not only to supply fish for harvest, but also to support recovery of ESA listed stocks.  Regional decision-makers acknowledge that the current technology is unproven and experimental and advocate using adaptive management to resolve uncertainties.  Monitoring the outcome of management experiments is a cornerstone of adaptive management.  The ISAB recommends initiating and supporting the immediate establishment of an adequate comprehensive monitoring program.  Investment in a monitoring program will be significant and may reduce the numbers of smolts released initially, however, eventual program improvements and the resolution of uncertainties and controversy should make the effort well worth it.

ISAB members are currently reading the Council's Fish and Wildlife program amendments, the FCRPS BiOP, the Governor's Plan, and the Federal Caucus All-H paper.  With our coordinators, Mr. McConnaha and Dr. Schiewe, we are discussing the appropriate role and format for the ISAB to review these documents.  For the hatchery portion of that review we intend to pursue the linked questions of experimentation, adaptive management, and monitoring, with a view to offering advice on how to implement these generalities in a specific program.

Sincerely,

Jim Lichatowich, Chair
