There was an interesting article by the head of WA State Fisheries in the teens (nine-teens) decrying the catch of immature salmon in the ocean, particularly off the mouth of the Columbia.

Besides the small size and chasing them they actually looked at "food quality" of the fish. The comparisons were with adults at local hatcheries. They were looking at "quality" from nutritional aspects and not such things as skin color. The highest quality was a springer while the lowest were the ocean caught fish.

Made for an interesting read.
