Green Sunfish
Lepomis cyanellus
Green sunfish have a relatively large mouth, a heavy body and dark green to bluish upper sides, often marked with turquoise spots and faint vertical bars. Adults feed on insects and small fish. They tolerate variable conditions in streams and ponds, and can hybridize with other sunfish, making identification more difficult. Despite regional nicknames, green sunfish are not rock bass. Check the rules for the exact water before fishing or retaining fish.
Freshwater streams, ponds and small lakes, including habitats with variable conditions. Shallow gravel or rocky areas provide nesting sites.

FishFinder links Green Sunfish to water records in Idaho and Illinois. These associations may reflect documented presence, seasonal runs, or historical stocking, not angler catch reports or current abundance. Read the linked water guides and source notes for evidence dates and reaches.
Green Sunfish Fishing Regulations & Limits
A recorded association does not establish that targeting or retaining Green Sunfish is permitted. Confirm current species protections, seasonal and emergency closures, reach-specific rules, gear restrictions, bag and size limits with the responsible fisheries authority before fishing. A fishing license does not override these restrictions. FishFinder's regulation records may be incomplete; missing rules do not mean unrestricted fishing.
