We, the National Marine Fisheries Service (NMFS), issue a final determination to retain the threatened listing for the Oregon Coast (OC) Evolutionarily Significant Unit (ESU) of coho salmon (Oncorhynchus kisutch) under the Endangered Species Act (ESA).

Hartman GF, Holtby LB, Scrivener JC () Some effects of natural and logging-related winter stream temperature changes on the early life history of coho salmon (Oncorhynchus kisutch) in Carnation Creek, British Meehan WR, Merrell TR Jr, Hanley TA Cited by: survival of hatchery and wild juvenile coho salmon in the Klamath River, but the results are from a single unusual water year. The results may be different during other water year types. The current information supports a positive relation between discharge at Iron Gate Dam and survival of juvenile coho salmon downstream, but additional data.

Declines in Pacific salmon Oncorhynchus spp. have been blamed on hydropower, overfishing, ocean conditions, and land use practices; however, less is known about the impacts of introduced fish. Most of the hundreds of lakes and ponds in the Pacific Northwest contain introduced fishes, and many of these water bodies are also important for salmon production, especially of coho salmon O. kisutch.

the years adult salmon migrate to freshwater to reproduce (spawn) and the hatched juvenile salmon (the parr stage) reside and grow in freshwater from a few days (as do pink and chum salmon) to more than a year for king, coho, and sockeye salmon.

The effects of logging and mass wasting on juvenile coho salmon (Oncorhynchus kisutch), steelhead trout (O. mykiss, formerly Salmo gairdneri), and Dolly Varden char (Salvelinus malma) were assessed in streams on the Queen Charlotte Islands. Fish densities and habitat characteristics of 27−33 stream reaches were measured during summer and fall.

Along the coast of Washington the abundance of coho salmon is controlled by natural mortality, exploitation by fisheries, and logging-associated mortality. Trade-off between growth rate and aggression in juvenile coho salmon, predation risk, and may also carry costs such as increased metabolic demand, with effects on growth.
To test the hypothesis that there is a trade-off between individual growth rate and aggression, we mated 12 female coho salmon with two unique males each, creating 24 full Cited by: Effects of artificial wood placement on movements of trout and juvenile coho salmon in natural and artificial channels.

As they draw down their yolk stores, juvenile salmon begin feeding on the stream’s insect life. There are six anadromous salmon species in the Pacific Northwest — Chinook, coho, sockeye, pink, chum, and steelhead.
Several studies have found otolith growth in juvenile salmon to be positively correlated with somatic growth (Marshall and ParkerWilson and LarkinVolk et al.Neilson et al. Consequences for coho salmon Carnation Creek, B.C. First logging effects Age 1 Age 2.

Therefore, in this study we examined how juvenile coho salmon respond, in terms of winter movement, growth, density and survival, to two different combinations of.
In summercoho salmon density in an entire reach of the north fork was fish/m2 (Burns ), and in summercoho salmon density in south fork pools was /m2 (Nakamoto, un-published data).
We used two-way analysis of variance (ANO-VA; main effects: stream and steelhead density) to analyze survival and growth of coho salmon.
