In 1950, the world's fleets landed 20 million tonnes of ocean fish.

They fished for salmon along rivers, gathered ocean fish and shellfish, hunted game, and gathered plants.

Salmon, clams, mussels, ocean fish, deer, elk, and smaller game have been traditional staples, as have wild berries and tan oak acorns.

Seafood predominates the menu, as shrimp, crab, and freshwater and ocean fish are widely available.

These large ocean fish are the species at the top of the food chains (e.g., tuna, cod, among others).
