Rock bass

Ambloplites rupestris

The bycatch that saves a slow day. A rock bass will eat almost anything you drop past it.

What the DNR measured

Shawano Lake data: No stand-alone table in the 2023 comprehensive report.
Regulation grouping: Managed with yellow bass and white bass, not with panfish.

What that means on the water

Rock bass are not a survey target here and the lake has almost no rock, so they concentrate on the few hard-bottom edges: rip-rap, dock cribs, bridge pilings and the outlet.

Where to find it

Fish the rip-rap and the bridge pilings.
Work the Shawano Outlet, which has the only real current.
Try dock cribs and any hard edge next to deeper water.

How to catch it

Crawler on a small jig.
Any small crankbait or spinner.
