Ecosystem effects on harvested populations : lower trophic level dynamics in the northeast pacific and its implications on sockeye salmon (oncorhynchus nerka) survival
Almost all epipelagic fish species in the Northeast Pacific show an increase in population size between the late 1950s and the 1980s. The complexity of pelagic ecosystems makes speculations on the causes of these increases easy to justify, and thus various conjectures on the chain of events leadi...
