Sea change – Major study links pink salmon and ocean chaos

Pink salmon and the hatcheries helped boost their numbers to never-before-seen highs were Thursday singled out for disrupting the ecosystem of the North Pacific Ocean to the detriment of other species of salmon, seabirds, whales and more in a peer-reviewed study published in the journal Marine Ecology Progress Serices (MEPS). The study titled “From diatoms to killer whales: impacts of pink salmon on North Pacific ecosystems” concluded that “the evidence is consistent and strong that pink salmon can exert competitive dominance for common-pool prey resources shared by four forage fish species, all five species of Pacific salmon and steelhead trout, and 11 species of seabirds. “It further indicates that pink salmon can have a strong influence on ecosystem structure and function by, for example, initiating pelagic trophic cascades.”  >>click to read<< 10:20
