Western pond turtles are omnivorous and most of their animal diet includes insects, crayfish and other aquatic invertebrates. Fish, tadpoles, and frogs are eaten occasionally, and carrion is eaten when available. Plant foods include filamentous algae, lily pads, tule and cattail roots.
Most turtles must be fed directly in the water; otherwise they cannot swallow. Turtles eat a variety of chopped lean raw meats and occasional greens. A few turtles like banana as a treat. Beef, fish, smelt and fresh shellfish, earthworms, tubifex worms and brine shrimp (for babies) should comprise their diet.
