ISRP Review of CRITFC Harvest Monitoring Proposals (2008-508-00 and 2008-502-00)
May 24, 2010 | document ISRP 2010-14 |
The attached memo contains the ISRP’s review of two Columbia River Inter-Tribal Fish Commission (CRITFC) Accord Proposals, Produce Statistically Valid Harvest Estimates (2008-508-00) and Increase Zone 6 Tribal Fishery Monitoring (2008-502-00). The ISRP provides the review of these proposals together because both were submitted by CRITFC, involve tribal harvest monitoring, and one proposal will inform the other. The Council requested our review on April 26, 2010.
Proposal 2008-508-00
This is an ISRP response
review for the Harvest Estimates proposal (2008-508-00). This project
intends to determine and formalize statistically valid sampling
protocols for tribal harvest estimates throughout the Columbia River
Basin. On August 26, 2009, we released our review of the initial
proposal and requested a response asking for (1) a summary of the
programs that use the escapement estimate data, (2) the sampling
criteria those programs require for robust analysis, and (3) a survey
design that will be adequate to determine if the creel census meets
the program needs (see ISRP
2009-37). The ISRP's attached memo provides a detailed review of
the adequacy of the response to these three issues. In sum, the ISRP
recommends that the proposal, augmented by the response, meets
scientific review criteria (qualified).
Proposal 2008-502-00
This is the ISRP's first
look at the proposal, Increase Zone 6 Tribal Fishery Monitoring
(2008-502-00). The proposal is intended to “improve the reliability of
catch estimates for Zone 6 tribal fisheries by increasing the
collection of tribal catch data through increased sample rates and the
use of new data collection methods. Tribal catch estimates are
required in real time to properly manage fisheries for conservation
and to fairly share the harvestable component of upriver runs between
treaty and non-treaty fisheries.” This project is intended to supply
additional sampling and analytical support to the Harvest Estimates
proposal, while information from the Harvest Estimates proposal may be
used to improve the sampling efforts carried out under this proposal.
The Zone 6 proposal is also intended to supply information to another
CRITFC proposal, Genetic Assessment of Columbia River Stocks (2008-907-00).
In sum, the ISRP found that the proposal does not provide enough
detail to evaluate the actions proposed, and thus the ISRP requests
a response.
