Since the initiation of the LSRCP's involvement in the PIT-tagging program, LSRCP-related PIT tags have been provided by BPA through PSMFC because the LSRCP Program costs are reimbursed to the U.S. Treasury. Providing the PIT tags directly saved the administrative costs associated with the LSRCP program purchasing the tags.
Biological results achieved
Estimates of juvenile migration timing, duration, and survival under various flow regimes have been provided for hatchery-reared chinook and steelhead released from LSRCP facilities both for monitoring and for a variety of evaluation studies. Additionally, several natural populations have been monitored that inhabit streams affected by the LSRCP Program.
Project reports and papers
A list of LSRCP reports can be obtained from the LSRCP Office; they are numerous.
Adaptive management implications
Knowledge of juvenile survival has allowed the programs cooperators to select the best time, location, and type of release for improved emigration survival and helped reduce the likelihood of adverse impacts on naturally-produced fish. Flow managers will also use data to determine flows which provide optimum survival.
Specific measureable objectives
Provide PIT-tags at an economical cost to cooperators so they can estimate juvenile LSRCP facility-reared steelhead and chinook emigration timing, migration, and survival from the point of release through the dams with detectors. PIT tags are used both as a monitoring devise for standard release protocols and as an evaluation tool for controlled experiments. Some natural populations are also monitored for comparisons to hatchery-reared fish.
PIT tags use is not new; and although their use presents some risk to the marked fish, they have much lower mortality rates than alternative methods.
Data are lacking which describe migration and survival characteristics of most populations of migrating juveniles. Most populations of Snake River chinook and many steelhead populations, both natural and hatchery-reared, have experienced poor migratory corridor survival in most years since the LSRCP Program was initiated in the early 1980's. Several LSRCP-affected chinook populations are now listed, and theLSRCP program is incorporating conservation programs to maintain many of these populations. Many hatcheries are now rear and release listed fish and some hatchery populations are part of an ESU. Although survival has improved in those years with higher springs flows, listed populations remain at low levels and hatchery populations are barely replacing themselves in most years.
Hypothesis to be tested
The hypotheses vary greatly among projects but generally include analysis of differences in migration timing, duration, or survival anticipated with various release locations, times, or types under various flow regimes. Some comparisons of stocks and type of rearing (e.g. natural versus hatchery) are also investigated.
Cold branding was used before PIT tags became the preferred tool but have not been considered for recent studies.
The experimental designs vary depending on the method and objectives of the individual monitoring or evaluation programs. Numbers of fish tagged varies based on the history of tag interrogations, i.e. the historical interrogation rates will help determine the number of tags needed to obtain a suitable number of recoveries for statistical studies (often 35 to 50 per test group).

SUMMARY OF EXPECTED OUTCOMES
Knowledge of juvenile migration timing, duration, and survival of a most hatchery and some natural-reared fish populations. Factors such as time, location, and type of release, as well as migration conditions and origin of stock, can be compared.
Results should influence time, location, and type of release and influence stock selection which should result in better early survival of releases.
Provisions to monitor population status or habitat quality
All LSRCP projects have extensive monitoring and evaluation programs which are ongoing and require PIT tags as an evaluation tool.
Data analysis and evaluation
PIT-tag data will be incorporated into the analyses of programs by the study leaders conducting LSRCP-funded studies
Information feed back to management decisions
All LSRCP projects are conducted by co-managers and findings are applied as they become available and are agreed to by co-managers.
