Pink salmon (Oncorhynchus gorbuscha) runs in the lower Elwha have been judged to be in jeopardy during the removal phase of Elwha River dams due to potential siltation of spawning areas. Protective measures that include a gene rescue captive broodstock for the odd-year class run component.
The NWFSC's Manchester Research Station is involved in a cooperative effort with the National Park Service (NPS), Lower Elwha Klallam Tribe (LEKT), Washington Department of Fish and Wildlife (WDFW) and others involved in salmon restoration activities associated with removal of Elwha River dams. Plans call for a portion of each Elwha odd-year class pink salmon to be reared in captivity for up to three brood years (2011, 2013, 2015), with the program phasing out after year 6.
The Manchester Research Station provides biosecure captive broodstock fish rearing space for the seawater portion of the fish's life cycle. The gene rescue captive broodstock programs plans are to make gametes available to allow the Lower Elwha Klallam Tribes Elwha Hatchery to rear and release juvenile pink salmon for supplementation efforts during the 2011-2015 brood cycles.
