Circulatory Function of Pink Salmon at the Spawning Grounds

  • Walter Garey
Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 241)


After having spent 18 months of their two-year life span in the Pacific Ocean, mature pink salmon (Oncorhynchus gorbuscha) 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. Upon arriving at the spawning grounds they deploy and hold their position in the stream until the spawning event. During this period in freshwater the fasting and exercising fish deteriorate greatly and age rapidly. Spawning is manifested quickly for some but as long as a month later for others in the population. The spawning spectacle itself is followed quickly and inevitably by death.
