Rainbow Trout


Rainbow Trout

Rainbow Trout in Maine are introduced, non-native fish that have established limited but significant populations in select waters.

These colorful salmonids are highly variable in appearance and show good growth by utilizing diverse forage and show better tolerance to marginal water quality and competition compared to native brook trout.

Physical Characteristics:
  • Highly variable in appearance, with olive to blue-gray dorsal coloration, silvery sides, white to pale yellow bellies, and characteristic large numbers of small black spots covering the body.
  • Distinguished by a prominent pink to red colored band extending from the cheek to the base of the tail.
  • Adults typically range from 8-16 inches, though some reach 7-8 pounds.

What to know

Habitat Distribution

  • Self-sustaining populations are concentrated in three main drainages.
  • They spawn almost exclusively in streams and rarely reproduce successfully in lakes lacking suitable tributary habitat.

Key Locations

  • Three main drainages: the Kennebec River (from The Forks to below Solon Dam, including Wyman Lake), the upper Androscoggin River (Maine/New Hampshire border to Bethel), and portions of the Dead River below Long Falls Dam.
  • Specific locations include Little Ossipee Lake in Waterboro, Middle and Upper Range Ponds in Poland, Norway Lake in Norway, and sections of the Kennebec and Androscoggin Rivers.
  • Long Pond's confluence of Great Pond Outlet proved most successful during experimental angling.

Specific Spots

  • In rivers, focus on riffle sections above larger holding pools and tail-outs below pools.
  • Summer: deeper waters typically 30-35 feet.
  • Ice fishing: relatively shallow water under 15 feet targeting near or on the bottom.
