Short description
The evaluation of the effectiveness of squawfish management is an integral component of the ongoing program. Changes in squawfish age and size distributions and predator consumption of juvenile salmonids is being assessed by ODFW through biological sampling; computer modeling is the primary basis for estimating survival benefits to juvenile salmonids, including inter- and intra-specific compensation. NBS is also conducting bioenergetics modeling as an alternative, corroborating evaluation method. This project simply serves to enhance the ongoing evaluations, if necessary, to ensure rigorous and timely assessment of this program.

Management implications

Specific measureable objectives

Testable hypothesis
B.5.1. Squawfish removal, which results in reduced numbers, reduction in mean age, and younger age structure of squawfish in segments of the migration corridor does not improve survival of smolts passing those segments.
B.5.2. Altered squawfish numbers and population structure in segments of the migration corridor does not cause increased predation by other fish species in those segments.

Underlying assumptions or critical constraints


Brief schedule of activities

Biological need
Direct assessments of the effectiveness of squawfish removals on juvenile fish survival would be desirable, if feasible. Such information even on a local scale would be complementary to ongoing biological evaluations and aid in the validation of model results.

Critical uncertainties

Section 3. Budget

Data shown are the total of expense and capital obligations by fiscal year. Obligations for any given year may not equal actual expenditures or accruals within the year, due to carryover, pre-funding, capitalization and difference between operating year and BPA fiscal year.
