Pink, chum and sockeye salmon have been doing really well over the past few decades. A new study published in Marine and Coastal Fisheries finds in the North Pacific, those species’ abundance levels have been peaking over the past 25 years. But more salmon can be a bad thing. Evidence suggests that more pinks, chums and sockeye are contributing to declining king salmon stocks.
Greg Ruggerone is a scientist with Natural Resources Consultants INC., and he’s been studying levels of salmon in the North Pacific.
