The Strait of Juan de Fuca Intensively Monitored Watershed (IMW) began in 2004 to test the watershed-scale response of steelhead and coho salmon to watershed restoration. The Strait IMW includes two treatment watersheds (East Twin River and Deep Creek) and one control watershed (West Twin River). Restoration treatments included LWD placement, road and culvert removal, off-channel habitat creation, and riparian planting. Monitoring of physical habitat as well as coho and steelhead parr densities began in 2004 using the EPA’s EMAP site selection and sampling protocols. Smolt and adult monitoring predates the IMW program and began as early as 1998 in some watersheds. Preliminary results suggest an increase in pool habitat and small increases in steelhead adults and smolts in East Twin River, as well as adult coho in Deep Creek. PIT tagging has revealed a large outmigration of age-0 coho in the fall that contributes to the adult return, stream swapping by juveniles, and varying return times for coho adults. Current research has answered a portion of our original questions and has raised new ones. Restoration treatments were completed fairly recently or are still in progress. As habitat typically does not respond immediately to treatment, additional years of monitoring are needed to determine watershed-scale fish response. Moving forward, analysis of otoliths to validate PIT tag data and new restoration methods such as carcass or nutrient enhancement may be merited. PIT tagging and habitat data. Includes fish weight, length, location, and PIT tag number. Habitat data includes wood measurements and stream surveys.

In the early 1990s, Redfish Lake sockeye salmon from the Sawtooth Basin in Idaho were on the brink of extinction, and they were listed as endangered under the US Endangered Species Act in 1991. To prevent extinction, a gene rescue captive broodstock program was established for the stock that consisted of taking most of the remaining gene pool into captive culture at specialized conservation hatcheries at the Manchester Research Station and the Idaho Department of Fish and Game Eagle Hatchery. Efforts through the decade of the 1990s consisted of developing techniques for successful culture of sockeye salmon to adulthood, establishing rearing and spawning protocols to ensure preservation of stock diversity, and habitat enhancement at the rearing lakes. In the early 2000s, the program began to include a demographic focus to boost the population through rearing and release of enough juveniles to produce some adult returns. For the last few years, NWFSC eyed egg production has resulted in over 150,000 smolts being released into the Stanley basin annually for recovery, with plans to increase NWFSC eyed egg production to support release of half a million smolts in the Stanley Basin by 2017. In 2011, and for the fourth year in a row, record numbers of sockeye adults have returned to their native home in Idaho. This work is collecting data on the length, weight, and survival of sockeye salmon ponded under two different incubation temperature profiles.

All fresh mortalities larger than 100 mm are sent to Fish Health for pathology. Autopsy data is maintained on their database.

This population historically migrated as subyearling smolts, but in recent years, the yearling life history has become more common. Environmental conditions associated with dams and reservoirs might be exerting strong selection for alteration of life history traits that evolved over millennia. This project attempts to determine the extent to which these life history changes are due to evolution (genetic change) as opposed to phenotypic plasticity (non-genetic response to different environmental conditions).

Gene rescue captive broodstock program was established for ESA-listed endangered Snake River sockeye salmon from Redfish Lake, Idaho. The program has consisted of taking most of the remaining gene pool into captive culture at specialized conservation hatcheries at the Manchester Research Station and the Idaho Department of Fish and Game Eagle Hatchery. Fish are being released to native habitats as part of recovery efforts. Data is collected by broodyear on % survival to eye, % survival to spawning, % survival to smolt, % survival to adult, % maturity as two year olds, % maturity as three year olds, and % maturity as four year olds. Age of maturity data is available by sex.

The objective of this project is to develop a simple approach for estimating the marine survival and causes of trends in survival. Data is a summary of ecosystem indicators of coho salmon marine survival.
