Creek Chub
Semotilus atromaculatus
The creek chub is one of the commonest stream fishes across Ontario, Quebec and the Maritimes — and the classic first fish for creek kids, taken on a dry fly or a micro hook in any small brook.

Habits

Where they live
How to catch them
Micro-hook bait fishing River
Rig: Ultralight rod, size 14-20 hook with a tiny piece of worm under a small float or free-lined in pools
Bait/lure: Worm pieces, bread
Key tip: Use the smallest hook you own — chubs nip, so keep baits tiny and watch for the lightest tap.
Dry-fly creek fishing River
Rig: Light fly rod or tenkara, small dry flies and nymphs cast to pool heads and undercut banks
Bait/lure: Dry flies, small nymphs
Key tip: Creek chubs rise freely to dry flies in summer — a perfect, forgiving first fly target.
