Too Many Salmon in the Sea, Pacific Study Hints

Too many fish in the sea? Surging pink salmon stocks in the Pacific Ocean pose a risk to other wildlife, suggests a seabird study released on Monday that points to climate change as a culprit. (Related video: "Alaskan Salmon Adventure.")

Along with other salmon, pink salmon (Oncorhynchus gorbuscha) numbers have grown since the 1970s, with an estimated 640 million returning to their breeding rivers in Asia and North America in 2009 alone. (Read "The Long Journey of the Pacific Salmon" in National Geographic magazine.)

Tied to rising ocean temperatures in the Bering Sea and North Pacific that spurred the growth of the prey of salmon and seabirds alike, the "much larger than previously known" impact of pink salmon is reported in a new Proceedings of the National Academy of Sciences report.

It's "an uncommon case of too many fish in the sea," says the report. The study, led by Alan Springer of the University of Alaska Fairbanks, found that salmon eating the food of seabirds appears to be cutting the birds' .... http://news.nationalgeographic.com/news/2014/03/140331-salmon-seabirds-pacific-fish-animals-science/

Wonderful PR for the commercial fishing industry, crap wrote article imo. I know there's too many Pinks. There's also too many people targeting the other 3 species of Salmon leaving tons of food for the pinks to eat. Fire away you PR maggots.

I vote for reducing the hatchery component before more commercial fishing.
but as in all things, natural populations are cyclic. Man doesn't understand those cycles.

CNC - I believe that you are correct. Those that say the solution is to throw as many hatchery fish out there as possible do not understand the cycles any better than I do.

Man is also harvesting the whole food chain heavily and then wondering why the top end collapses.
