Those predators have to eat year around so when the wave of salmon smolts pushes out into the ocean they focus on what remains......to include forage fish. As I remember when WDFW was developing its rockfish recovery plan the number of seals was estimated at around 15,000 and their collective annual food requirements were in the neighborhood of 28 million pounds. Close to 20,000 seals now - do the math.
