How to catch a pile perch

Bait
Mussel meat (#1), bloodworms, market shrimp, sand crab
Rig
Light hi-low with two #6 baitholder hooks, 1/2–1 oz sinker, 10 lb mono

Fish tight against pier pilings or rock walls. Pile perch suspend at mid-depth, not on the bottom. Float rig with a small bait at 1/3 the water depth often outproduces bottom fishing.

Seasonality

Year-round at piers; best spring (Mar–May) when pre-spawn females feed heavily. Summer slows after birthing.

When they bite
Tide preference
Slack high or incoming through high

Common mistakes

What anglers get wrong

Frequently lumped as "perch" by piler anglers — there are actually 8+ surfperch species in SoCal. Forked tail and large size separate pile perch.
