Vertebral Abnormalities in Sockeye, Pink, and Chum Salmon

Transactions of the American Fisheries Society, 1966
Abstract Radiographs of vertebral structures of 10,377 sockeye, 4,403 chum, and 4,777 pink salmon collected in 1958 to 1962 were examined to determine the frequency of occurrence of abnormal vertebrae in wild populations of mature Pacific salmon. Various types of deviations from the orderly processes of development or segmentation that resulted in ...

An Improved Sibling Model for Forecasting Chum Salmon and Sockeye Salmon Abundance

North American Journal of Fisheries Management, 2007
Abstract The sibling model is often one of the best methods for calculating preseason forecasts of adult return abundance (recruits) for populations of Pacific salmon Oncorhynchus spp. This model forecasts abundance of a given age-class for a given year based on the abundance of the previous age-class in the previous year.

Responses of Coho and Chum Salmon Fry to Current

Journal of the Fisheries Research Board of Canada, 1953
Chum and coho salmon fry respond positively to changes in water flow by swimming against the current. The magnitude of the response varies with the intensity of the current. Currents eliciting optimum response differ for the two species. Both species respond to the stronger of two parallel laminar currents but, after a time, coho fail to discriminate ...

Marking Chum Salmon Fry Vertebrae with Oxytetracycline

North American Journal of Fisheries Management, 1986
Abstract An experiment was conducted to determine the effectiveness of oxytetracycline (OTC) as a method of marking chum salmon (Oncorhynchus keta) fry vertebrae. Three groups of fry that originated from a gravel box incubation system and three groups that originated from a Japanese-style (channel) incubation system were treated with an OTC-Oregon ...

The Behaviour of Migrating Pink and Chum Salmon Fry

Journal of the Fisheries Research Board of Canada, 1956
Pink salmon fry which have never schooled are negatively phototactic, prefer a cover of stones and do not emerge into bright light. Those which have schooled show a strong cover reaction when exposed to a rapid increase in light intensity but do not seek cover unless the change is abrupt. In general they remain in bright light after they have schooled.

Ocean Growth and Mortality of Pink and Chum Salmon

Journal of the Fisheries Research Board of Canada, 1964
Records of length of pink and chum salmon computed from scale annuli are summarized, and are converted to show rate of growth in weight. Information is available on 11 pink stocks or groups of stocks originating at points from the Strait of Georgia to Sakhalin and Primorye, and for 7 chum stocks taken from Tillamook Bay to the Amur River and Sakhalin.

Vibriosis Vaccination of Chum Salmon by Hyperosmotic Infiltration

The Progressive Fish-Culturist, 1978
Abstract When fry of chum salmon (Oncorhynchus keta) started to feed, they were vaccinated with Vibrio anguillarum bacterin by hyperosmotic infiltration. Mortalities of vaccinated and unvaccinated fish were compared in ambient and controlled challenge experiments.
