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
