Letty ... it would be nice to see sea lions / seals at normal historic populations ... but the remainder of the predators you mention are part of the wild and play an essential role in the natural selection process ... slow, weak, or diseased ones get it ... the tough ones don't.

Unfortunately gillnets (and yes, some sporties) often kill a higher percentage of the biggest, strongest (repeat spawners forced to run the gauntlet of nets a few times) members of the population ... those are things that need to go ...
