Green Sunfish FAQ

Answers from onWater's species guide.

What are the best lures and bait for Green Sunfish in Washington?

For live bait, nightcrawlers and worms are highly effective - use only portions (1/2 or 1/3 of a worm) threaded on the hook with some left hanging to create movement. Small insects like crickets, grasshoppers, and wax worms also produce excellent results.

What flies work for Green Sunfish in Washington?

For fly fishing, use patterns in sizes #8-#14 including small streamers, nymphs like San Juan worms and brassies, soft hackles, and small poppers. Avoid oversized surface flies and minimize action - small patterns like Foam Ants or Micro Chubby Chernobyls with rubber legs work better than large poppers.

When is the best time to fish for Green Sunfish in Washington?

The best fishing occurs during late spring through summer, particularly around dawn and dusk when they're most active.

How do you catch Green Sunfish in Washington?

Slower retrieves typically work better than fast presentations, and they often inspect offerings before committing to a strike. For live bait, use only portions (1/2 or 1/3 of a worm) threaded on the hook with some left hanging to create movement.

Green Sunfish are opportunistic omnivores with a diet including aquatic insects and larvae, terrestrial insects, crayfish, snails, small fish, fish e.g.gs, zooplankton, and sometimes plant material.
