Insects:
* Aquatic insects: Nymphs, larvae, and adult forms of mayflies, stoneflies, caddisflies, and dragonflies are a staple food source.
* Terrestrial insects: Tiger trout will also opportunistically eat ants, beetles, and grasshoppers that fall into the water.
Other Invertebrates:
* Crustaceans: Crayfish, shrimp, and other crustaceans are important food sources, especially in larger tiger trout.
* Worms: Earthworms and other aquatic worms are readily consumed.
Fish:
* Smaller fish: As tiger trout grow larger, they become increasingly piscivorous (fish-eating). They will prey on smaller fish like minnows, sculpins, and even other trout.
* Eggs: Tiger trout will also eat the eggs of other fish, especially during spawning season.
Other:
* Amphibians: Tadpoles and small frogs are occasionally eaten.
* Small mammals: Tiger trout can even consume small mammals like mice or voles that fall into the water.
Note: The specific diet of a tiger trout will vary depending on its location, age, and the availability of prey in its environment.
