The photoperiod control of coho salmon smoltification

Aquaculture, 1982
Abstract Photoperiod has been implicated as an effective mediator of coho salmon smoltification. To investigate the possibility of manipulating photoperiod to control the occurrence of this event, a study on coho salmon (1.7 g initial weight) was conducted over a 24-week period. Of the treatments tested: natural; rate extended; sustained maximum; and

Metabolic effects of salmon glucagon and glucagon-like peptide in coho and chinook salmon

General and Comparative Endocrinology, 1989

Acute toxicity of boron, molybdenum, and selenium to fry of chinook salmon and coho salmon

Archives of Environmental Contamination and Toxicology, 1990
The acute toxicities of boron, molybdenum, and various forms of selenium, individually and in environmentally relevant mixtures, to swim-up and advanced fry of chinook salmon (Oncorhynchus tshawytscha) and coho salmon (O. kisutch) were determined in site-specific fresh and brackish waters.

Accuracy of Underwater Counts of Juvenile Chinook Salmon, Coho Salmon, and Steelhead

North American Journal of Fisheries Management, 1992
Abstract Underwater observers counted juvenile salmonids in study areas on mid-Columbia River tributaries, and the accuracy of these counts was examined. We compared counts taken by two to six experienced snorkelers with counts obtained after use of sodium cyanide in the same sites at stream temperatures that ranged from 5.6 to 18.3°C.

Flavobacteriosis in Coho Salmon (Oncorhynchus kisutch)

1980
Salmon production in Spain has been increasing during the past years. Geographical areas for these cultures are located in estuaries rich in phytoplankton and Zooplankton in North Spain. Most of the pathological problems are related to diseases already found in other countries. Among them vibriosis and kidney disease stand out (ACUIGRUP, 1977). Special
