Brown TroutBrown trout are native to Europe and were introduce to tributaries in the Grand Canyon in the 1920s. They are capable of withstanding slightly higher temperature than other trout. Unlike most other trout species, brown trout spawn in the late fall. Their spawning behavior, however, is similar to other trout species. Like rainbow trout, young brown trout feed on aquatic and terrestrial insects and invertebrates but brown trout are more apt to switch to larger prey like fish as they get bigger than the rainbow trout found in Grand Canyon. Many studies have shown that native fish often have a difficult time persisting with large populations of brown trout.[1] Desired Future Condition for the Lees Ferry Trout FisheryA high quality trout fishery in GCNRA, as further described in the Recreation DFC that does not adversely affect the native aquatic community in GCNP. |
