Northern Sunfish
Lepomis peltastes
A northern relative of the longear, split from it by a shorter ear flap edged in bright red-orange at the rear. It lives in the clear, cool, vegetated lakes and slow streams of Great Lakes country. In Ontario, the Great Lakes–Upper St. Lawrence population is listed as Special Concern under Canada's Species at Risk Act.

Identifying features
- Ear flap shorter than the longear's, with a bright red-orange rear edge
- Wavy blue-green lines on the cheek and gill cover
- Breeding males are orange below with blue-green markings above
- Deep, compressed sunfish body with a small mouth
- Orange-brown sides with blue-green flecks, duller in females and young
Habits

- Males fan gravel nests in shallow water in early summer and guard them
- Feeds on insects, small crustaceans and snails around weeds and docks
- Often mixes with pumpkinseed and bluegill in vegetated lakes
- Wary in very clear water — quiet approaches and small baits work best

Where they live
How to catch them
Small baits and flies in clear lakes River
Rig: Ultralight rod or light fly rod, small float and size 10-12 hook, or a small fly cast along weed edges in clear vegetated lakes and slow streams

Key tip: Approach quietly and use fine line — in clear northern water these fish spook easily.
Micro jigs around weed edges Shore
Rig: Ultralight spinning tackle with a 1/64-1/32 oz micro jig worked slowly along weed edges and dock posts
Bait/lure: Micro jigs, tiny soft plastics
Key tip: Fish early summer, when males guard gravel nests in the shallows.
Best baits & lures
