How To Catch Rainbow Smelt
Rainbow smelt are popular species with anglers for eating as well as for bait. Smelt are caught by ice fishing, jigging, seining, dip netting, and other techniques.
Rainbow smelt are a schooling species. In late winter they congregate near streams or shorelines with spawning habitat. Pre-spawn fishing requires locating schools of fish.
In areas where ice fishing is possible, fishing huts are often set up over schools of smelt. Anglers fish with multiple outfits, rigged with small hooks and baited with insect larvae, worms, small minnows, or other baits.
Rainbow smelt are also caught with small jigs, metal spoons, and other lures that mimic baitfish. Jigging with lures is sometimes necessary when fish are suspended in the water column.
In early spring as water temperatures increase, rainbow smelt begin moving into streams or other spawning areas. During spawning runs, rainbow smelt are sometimes netted in large quantities.
