The Snake River has experienced substantial declines in populations of anadromous salmonids
over the last century, which led to the listing of several populations under the Endangered Species Act (NRC, 1996; NMFS, 1997).
Reproductive performance of a newly described salmonid
fish, Alakir Trout (Salmo Kottelati), a candidate species for aquaculture.
There was also significant predation on Pacific Staghorn Sculpin, likely due to nearshore exploitation of a highly-available nearshore resource associated with salmonids
(McCabe and others 1983).
This dual agenda fuelled research into salmon biology and aquaculture in Britain and France that would ultimately shape the decision to acclimatise salmonids
Did blooms of Didymosphenia geminata affect runs of anadromous salmonids
on Vancouver Island?
We used a Pink Salmon (Oncorhynchus gorbuscha) otolith-loss correction factor for all salmonids
, a Shortbelly Rockfish (Sebastes jordani) correction factor for all rockfish species, and species-specific correction factors for Shiner Perch and Pacific Staghorn Sculpin (Leptocottus armatus) (Harvey, 1989; Phillips and Harvey, 2009).
Pacific anadromous salmonids
continue to migrate in the ocean along the southern California coast but, with the exception of steelhead, only occasionally enter streams and do not currently appear to reproduce in southern California.
Intensified production of salmonids
in on-shore systems (RAS) from brood stock to harvest combining freshwater and sea water is an emerging alternative (Wolters et al.
Hatcheries are efficient at producing fish for harvest, the researchers said, but this and other studies continue to raise concerns about the genetic impacts that hatchery fish may have when they interbreed with wild salmon and steelhead, and whether or not they will help wild salmonid
runs to recover.

The range of outlet concentrations and loadings from salmonid
smolt farms (in which salmonids
are grown up to the smolt stage from juveniles) is generally larger than from salmonid
grow-out farms (in which salmonids
are grown to market size from a mixture of juvenile and young or exclusively young salmonids
If the Pacific lamprey are stressed because they are going down the river in barges or because they are trying to negotiate fish ladders designed salmonid
, we can now monitor that stress using this finding.
