Circulatory Function of Pink Salmon at the Spawning Grounds

1972
After having spent 18 months of their two-year life span in the Pacific Ocean, mature pink salmon (Oncorhynchusgorbuscha) begin a spawning migration which instinctively leads them to the freshwater stream of their birth. Apparently they negotiate the hundreds of miles of the migratory route while abstaining totally from eating.

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.

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

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.

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.

Spawning Behavior of Pink Salmon on an Artificial Redd

Transactions of the American Fisheries Society, 1972
Abstract The spawning behavior of pink salmon (Oncorhynchus gorbuscha) was observed and photographed through a glass viewing port in the bottom of an artificial redd in an observation tank. Females readily accepted the artificial redd and completed the normal prespawning behavior sequences, including redd defense, digging, and crouching, but did not ...
