Annual reports generated for: 1990, 1991, 1992, 1993, 1994, 1995
Management implications
Data from this project gives information on survival, contribution, and stray rates of adult salmon released from WDFW hatcheries. This allows management to assess potential impacts of hatchery fish released at these hatcheries on listed species. It also provides information for potential harvest benefits to be accrued from hatchery operations.
Specific measureable objectives
Survival, contribution, and straying of WDFW Columbia River hatchery salmon.
Testable hypothesis
N/A
Underlying assumptions or critical constraints
Assuming that hatchery production will continue at all hatcheries earmarked to receive tagging.
Methods
Experimental Design: One or more production groups of each species of salmon will be tagged at each hatchery and survival, contribution, and straying among hatcheries and spawning grounds will be measured and compared. Data does not lend itself to rigorous statistical analysis, thus simple statistics are used to make estimates and comparisons. Approximately 1.0 million chinook, 350,000 coho, and 550,000 spring chinook will be tagged each year.
Brief schedule of activities
1997: 1) Tag 1.6 million juvenile salmonids; 2) recover and decode 2,000-5,000 tags from returning adults; 3) retrieve and analyze data from 1990 and 1991 brood chinook and 1992 and 1993 brood coho.
1998-2001: Increase number of tag groups from chinook and coho to be analyzed.
Biological need
Potential interactions with listed species need to be documented which cannot be accomplished without hatchery fish being identified as to their origin. Trends in survival and contribution are important for use in modeling effects of various biological and physical parameters encountered by hatchery salmon.
Critical uncertainties
Provides connection to other research or analysis projects because data can be used for purposes other than this project.
Summary of expected outcome
Adult survival and contribution trends will be analyzed for a ten year period, showing inter-hatchery variation. Stray rates will be estimated as will impacts to non-listed species.
Dependencies/opportunities for cooperation
N/A
Risks
Allows evaluation of current management of hatchery system. Without this data judgement and risk of hatchery operations cannot be made.
Monitoring activity
Continued evaluation of data reported in annual reports.
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.| Historic costs | FY 1996 budget data* | Current and future funding needs |
