Brown trout in Tennessee

Tennessee waters

Most fished first. A species missing from an agency list does not mean it is absent; this page lists only waters whose list names it (at least 5 are needed for a page).

Identification

• In California, the brown trout is the only trout with both red and black spots on its body. The dark spots on its sides usually have a pale halo.[2]
  What the source says

  “Only trout in California with both red and black spots on body. Dark spots on the sides typically surrounded by a pale halo. Coloration is usually dark to olive brown on the back, shading to yellow on the sides, and yellow or white on the belly.”

• Michigan DNR points to a broad, square tongue with 11 to 12 large teeth, light pectoral fins and a square tail. Lake-run browns are mostly silver, and their spots can be hard to see.[1]
  What the source says

  “Dorsal and adipose fin, broad square tongue with 11 to 12 large teeth, light pectoral fins, square tail, and nine to 10 rays in the anal fin. Lake-run browns are predominately silver in color and the body spots are often obscured in lake-dwellers compared to the resident stream dwellers.”

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.

• The U.S. Geological Survey reports that brown trout have been linked to declines in native fish, including other trout and salmon, through predation, displacement and competition for food.[3]
  What the source says

  “Brown Trout have been implicated in reducing native fish populations (including other salmonids) through predation, displacement, and food competition (Taylor et al. 1984).”

• Yellowstone National Park rule: in the Firehole River, Madison River and lower Gibbon River (below Gibbon Falls), all rainbow and brown trout must be released.[4]
  What the source says

  “Firehole River, Madison River, lower Gibbon River (downstream of Gibbon Falls)—possession of up to five brook trout is allowed. Catch and release all rainbow and brown trout.”

Water temperature in Tennessee

Tennessee Wildlife Resources Agency publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Tennessee rule:

• Under the federal 68°F lineThat is under the 68°F at which the National Park Service, at Grand Teton National Park, recommends anglers stop fishing in the afternoon (“cease fishing at 2 p.m. when water temperatures are likely to exceed 68°F”). Water warms through the afternoon, so check again later in the day: “Carry a pocket thermometer to monitor water temperature.”
• Stressful for troutAt 68°F the U.S. Fish and Wildlife Service says rainbow trout “start stressing”, and the National Park Service at Grand Teton recommends that anglers “cease fishing at 2 p.m. when water temperatures are likely to exceed 68°F.” Its advice: “Fish early in the morning while the water temperature is cooler”, “Play and land fish quickly to reduce exhaustion stress” and “Keep the fish in the water as much as possible.”
