How to Rig for Rock Bass

Ambloplites rupestris

Rock bass live exactly where the name says, around boulders, rip-rap, and rocky river bottoms, often in the same spots as smallmouth. They are aggressive for their size and will hit a worm or small grub all day, which makes them a great beginner fish on light tackle. Fish right next to the rock rather than open water nearby.

Float Rig

intermediateriver · lake

A float suspends bait at a fixed depth instead of dragging it on the bottom, letting current or light wave action carry it naturally past holding fish. This is the standard technique for salmon and steelhead in rivers, fished with roe or beads under a pencil float, and for light-tackle pier species like jacksmelt, where a small float and a multi-hook leader with tiny bait covers a school as it drifts through. Use it whenever fish are holding off bottom rather than on it, or when you want a natural drift through a current seam without snagging.
