Cutthroat trout prefer clear, cold, well-oxygenated waters in streams, rivers, and lakes
They thrive in habitats with gravel bottoms and abundant cover like rocks and vegetation
Their diet consists of aquatic insects, small fish, and crustaceans, making them opportunistic feeders
Juveniles are often found in shallow, slower-moving waters with plenty of hiding spots
Spawning occurs in spring, usually in gravel-bottomed streams with clean, cold water
Females dig nests (redds) in the stream bed to lay eggs, which are then fertilized by males
After hatching, fry remain in the stream for a year or two before migrating to larger bodies of water
Some populations are anadromous, meaning they migrate from the ocean to freshwater to spawn
