Trout.

California is known for Trout.

RAINBOW TROUT:

The rainbow trout is one of the most widely populated trout species. The pink and sometimes deep red band on their flanks gives the fish its name.

Life span: Rainbows mature when they are two or three years old, and rarely live more than five or six years.

Diet:

In rivers and streams, they feed on aquatic and terrestrial insects that drift in the water column, and may occasionally eat fish and frogs, especially as they grow larger. They may feed on small invertebrate worms or insect larvae on the bottom of some rivers and lakes. In lakes and reservoirs, they frequently feed on fish such as Threadfin shad.
