Unprecedented widespread occurrence of Pink Salmon Oncorhynchus gorbuscha in Ireland in 2017.

Journal of Fish Biology, 2019
The occurrence of non-native pink salmon Oncorhynchus gorbuscha in multiple river systems in Ireland in 2017 was unprecedented and reflected similar concurrent events observed in other countries in the North Atlantic region. Thirty-six fish were captured

A Revenue Analysis of the Alaska Pink Salmon Fishery

North American Journal of Fisheries Management, 1994
Abstract The Alaska salmon industry is suffering from declining prices due to an increasing supply of salmon worldwide, This has led to a much-needed economic evaluation of the Alaska salmon enhancement program and especially of the hatchery system for pink salmon Oncorhynchus gorbuscha. An econometric model of world salmon markets was used to evaluate

Record Size of Freshwater Pink Salmon

North American Journal of Fisheries Management, 1987
Abstract A record-sized pink salmon Oncorhynchus gorbuscha was caught on October 10, 1985, in the Bridgeland River, a tributary of the Thessalon River, which empties into Lake Huron. The male exhibited a pronounced humpback, sharp canine teeth, and large black spots over the back and the caudal fin.

Behavior of Displaced Adult Pink Salmon

Transactions of the American Fisheries Society, 1966
Abstract Studies to show whether pink salmon (Oncorhynchus gorbuscha, Walbaum) will repeat their original choice of spawning area when captured and transported to another location were done in Olsen Creek, Prince William Sound, Alaska, in 1961, 1962, and 1963.

Independent lineages in a common environment: the roles of determinism and contingency in shaping the migration timing of even- versus odd-year pink salmon over broad spatial and temporal scales.

Ecology Letters, 2019
Studies of parallel evolution are seldom able to disentangle the influence of cryptic environmental variation from that of evolutionary history; whereas the unique life history of pink salmon (Oncorhynchus gorbuscha) presents an opportunity to do so. All

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 ...

Temperature Relationships in a Pink Salmon Stream in Alaska

Ecology, 1961
dance, and ecology of these species are discussed. 5. There was no evidence of succession in Alamitos Bay Marina. The principal species were dominant during the entire period of study. The bottom fauna was compared with the other portions of Alamitos Bay, Lower Newport Bay, and outer Los Angeles-Long Beach Harbors. In general, the faunas of all regions

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.
