It seems that humans first and most favorite answer is to eliminate the competitor. It is true that the pinniped numbers are above some level set by the Feds that in all likelihood has little basis is ecological reality.

We don't know how many there were so we really don't know how many there should be other than a population large enough to "delist", which is the same for salmon.

Today's wild runs are probably 1/10 to 1/20 of what they were pre-industrial fishing (on all species) and human development. That number supported pinnipeds, whales, birds, grizzlies, humans, and who knows what else.

The problem, to me, is we have to decide first if we are willing to share this little blue ball with other animals. If so, how many of them? Which leads to how many of us. We also have to figure out that if we want, say, 100 SRKW then how many salmon of all species are needed to feed them. How many forage fish are needed to feed the salmon? Then, add in pinnipeds, birds, and all that. If there is anything left over then there is human harvest available.

Right now, the tail wags the dog. People need/take X. The ecosystem gets what's left.
