Angling tips

  • very popular, feisty sporting fish
  • usually caught near the surface and leap repeatedly, changing direction quickly
  • smaller than Chinook salmon
  • aggressive and likely to bite a wider range of baits and lures
  • usually stop feeding once they move upstream in fall, but are aggressive and territorial and will hit lures in defense--try rattle baits, spinners and plugs
  • down rigging and trolling work best when fishing in the Great Lakes
  • troll deep with plugs, spoons and live or dead bait
  • still-fish in moderately deep water using live, salted or fresh-cut herring

Common baits

  • plugs, spoons
  • trolling flies
  • live or dead bait
