Pinks are the poor relations of the salmon world, although they shouldn't be. They lack the superstar appeal of king (chinook) salmon and they're not even in the second tier with sockeye and coho. And pinks are small. Along with chum, pinks are just plain fish.
They're not bad fish at all, I love a good canned pink salmon. And in biological terms, there's no reason to not think pink when thinking about salmon. Pink salmon are important ecologically, so they might be the superstar salmon for an animal like, say, a killer whale.
So even though you've barely heard of pink salmon, there's reason to feel bad about the recently reported decline of pink salmon off British Columbia. In particular, pinks are in big trouble near salmon farms.
The scientist responsible for uncovering this problem was recently profiled in the New York Times, and featured on the Island of Doubt blog for her achievement in science without benefit of the typical pedigree, gasp she doesn't have a Ph.D.! How dare she wade in these waters without a license???!!
