Behavior

  1. Cutthroat trout are known for their aggressive feeding habits and territorial behavior. They are primarily carnivorous, feeding on insects, smaller fish, and crustaceans. These trout are also known for their remarkable adaptability, thriving in a wide range of environments from high mountain streams to large lakes.
  2. Cutthroat trout often exhibit migratory behavior, particularly in river systems where they may travel significant distances to spawn. Spawning typically occurs in the spring when they seek out gravel-bottomed streams to lay their eggs. The cutthroat trout’s migratory patterns and spawning behavior are crucial for the species’ survival, especially in environments where conditions can change drastically.

How to Identify

  1. Cutthroat trout are easily recognizable by the distinctive red or orange slash marks located on the underside of their lower jaw. These marks give the fish its common name, “cutthroat.” Their body coloration varies depending on their habitat, ranging from olive-green to silver, with a lighter belly. They are often adorned with small black spots that are more concentrated towards the tail.
  2. The cutthroat trout’s dorsal fin is usually covered in small black spots, which can also extend onto the tail and upper body. Unlike other trout species, the cutthroat has fewer, more scattered spots on its sides. Their fins are typically clear to slightly yellowish, further distinguishing them from other trout species.
  3. In terms of size, cutthroat trout are generally slimmer and more streamlined compared to their rainbow trout relatives. The coloration of cutthroat trout can also change slightly during spawning, becoming more vibrant, with males often developing a more pronounced hump on their back.
