Identification

• Rainbow trout vary a lot in colour and shape. Adults are silver with many small black spots, a pink or red band along the side, and spots that often run in lines along the tail rays.[2]
  What the source says

  “Highly variable in color and body shape, especially between resident fish and steelhead. Adults are silver and heavily spotted with small black spots. Iridescent pink or red along the lateral band. Numerous black spots pepper the body and dorsal fin, often radiating in lines along the rays of the tail.”

• The cheeks are pink and the back ranges from iridescent blue to nearly brown, with silver, white or yellow sides and belly. Young fish carry large, dark oval parr marks along the lateral line.[2]
  What the source says

  “Opercula (cheeks) are pink, the back iridescent blue to nearly brown, and the sides and belly silver, white or yellow. Juveniles have oval parr marks along the lateral line that are large and dark.”

• Rainbow trout and steelhead are the same species. Rainbows stay inland, while steelhead are the form that migrates to the ocean or, in Michigan, the Great Lakes.[1]
  What the source says

  “Genetically rainbow trout and steelhead are the same species but lead very different lives. Rainbow trout stays inland, and an anadromous form that migrates to the Great Lakes (or ocean in their native habitat).”

Status, protections and rules

As each agency stated them on the date read; a rule applies only where its agency says so. Check the current regulations for the water before you fish.

• In Great Smoky Mountains National Park, rainbow trout are non-native. The National Park Service says rainbow trout introduced in the early 1900s, together with logging, cost native brook trout 75% of their habitat.[3]
  What the source says

  “In the early 1900s, significant environmental changes occurred in the park due to logging and the introduction of non-native rainbow trout, which destroyed 75% of the native brook trout's habitat. Rainbow trout out-competed brook trout by reproducing at a faster rate as well as growing faster, taking over the streams.”

• Yellowstone National Park rule: in the Lamar River drainage, including parts of Slough and Soda Butte creeks, every rainbow trout caught must be killed. Releasing one alive is illegal there.[4]
  What the source says

  “All rainbow trout, brook trout, and identifiable cutthroat/rainbow hybrids caught in the Lamar River drainage, including portions of Slough and Soda Butte creeks, must be killed—it is illegal to release them alive.”
