Effects of petroleum exposure on predatory behavior of coho salmon (Oncorhynchus kisutch)

Bulletin of Environmental Contamination and Toxicology, 1981
Evaluations of the effects of petroleum on the indigenous marine fauna of Alaska's continental shelf regions are of continuing importance because of existing and proposed oil exploration activities in these areas. The purpose of the present study was to determine the influence of crude oil in seawater on salmonid predatory behavior.

Ontogeny of the olfacto‐retinalis projection in coho salmon (Oncorhynchus kisutch)

Journal of Experimental Zoology, 1991
AbstractFilling of nucleus olfacto‐retinalis neurons by cobaltous lysine injections into one eye of coho salmon of different ages revealed that the terminal nerve projection to the retina is established when the fish leave their freshwater environment. At this time salmons go through a metamorphosis termed “smoltification”.

Amoebic gill infection in coho salmon Oncorhynchus kisutch farmed in Korea

Diseases of Aquatic Organisms, 2016
About 70% mortality occurred in cultured coho salmon Oncorhynchus kisutch at a marine farm in the South Sea of Korea in 2014. Diseased fish showed greyish or pale patches on the gills, with no internal signs of disease. No bacteria or viruses were isolated from diseased fish, but numerous amoebae were found on the gills.

Saprolegnia diclina Humphrey as a parasite of the solmonid, Oncorhynchus kisutch.

2011
Studies of Saprolegnia infections of fish in British Columbia were made to determine disease causing agents and infection conditions. Saprolegnia diclina Humphrey was the most frequently observed parasite. This fungus reproduced sexually both on fish tissue and hemp seed cultures. No definite isolations of S.
