Impacts of Hatchery Production on Natural-Run Salmon and Subarctic Pelagic Ecosystems

Abstract Excerpt:
The pelagic phase of Pacific anadromous salmonid life cycles is crucial in regulating the growth and survival of these species, which are of vital ecological, economic, and cultural importance to North Pacific countries.  However, ecological interactions among salmonids, as well as between Oncorhynchus spp. and their predators, prey, and competitors, in the pelagic ecosystems of the subarctic Pacific Ocean remain an area of active research.
