In Wisconsin, the green sunfish occurs in the Mississippi River and Lake Michigan drainage basins. It is well distributed in streams and lakes in the southern one-third of the state, and it is widely dispersed northward. The green sunfish usually inhabits quiet pools in warm, shallow waters of ponds, lakes, small brooks, and rivers of low gradient.
Spawning takes place late May to early August. Green sunfish typically bring off multiple hatches each season, spawning every 8-10 days. The male builds a nest by clearing a depression in the lake or stream bottom to expose gravel. The nest usually is situated near the shelter of rocks, logs, or clumps of grass. After the femal spawns the male guards the nest, fanning it with his fins to keep it clean and well oxygenated.
