Kamchatka steelhead Oncorhynchus mykiss are the last of their race where the natural diversity of population structure still exists and all stocks remain free of genetic interactions from fish-culture operations. In recent years, the number of Kamchatka steelhead populations, especially anadromous forms, has declined sharply. The present study is based

Ether Anesthesia of Steelhead Trout
Transactions of the American Fisheries Society, 1941Abstract The use of anesthetics offers numerous advantages when handling, marking, or spawning fish which are susceptible to fungus diseases and injuries. Small trout were weighed and measured easily while anesthetized. Steelhead trout, under anesthesia, were very easy to spawn artificially and the loss from eggs so obtained was less than average ...

Coronary Disease in Spawning Steelhead Trout Salmo gairdnerii
Science, 1968Coronary degeneration was absent in young trout taken in fresh water and rare in immature fish at sea, but the incidence and severity were sharply greater in migrating fish and almost uniformly present in spawning fish. Several fish taken after they had reentered salt water after spawning had no lesions; lesions in fish taken during their second ...

Population Thinning to Control Furunculosis in Steelhead
North American Journal of Aquaculture, 2006Abstract Furunculosis, which is caused by Aeromonas salmonicida, is a major source of mortalities at hatcheries rearing coldwater fish species, such as salmonids. Thinning and density reduction during an outbreak may be a viable method to control mortality. In this study, we tested whether a significant reduction in mortality would occur

Population Structure of Steelhead in Coastal California
Transactions of the American Fisheries Society, 2014AbstractSteelhead Oncorhynchus mykiss are the most widespread of the Pacific salmonids Oncorhynchus spp. and are found in nearly all basins within their native range around the northern Pacific Rim. Here, we elucidate genetic population structure of steelhead in coastal basins from most of their coastal‐California range using variation at 15 ...

Methods of Controlling Growth of Steelhead
The Progressive Fish-Culturist, 1987Abstract Steelhead (Salmo gairdneri) held at 15°C and fully fed from demand feeders grow larger than desired by the time of their normal release into streams. The effect of limited feed intake on growth, body composition, and potential for migration to the sea was investigated.
