How to catch a spotted bay bass

Bait

Live anchovy (#1), 3" swimbaits (MC Slug-Go, Keitech FAT 3.8), live mud shrimp

Rig

Drop-shot rig with 1/4 oz tungsten weight, 12 lb fluoro, #1 EWG hook; or weedless swimbait on 3/8 oz jighead

Technique

Bay structure fishing — work eelgrass edges, dock pilings, rip-rap walls. Slow drag the swimbait along the bottom with subtle hops. Spotted bays attack from cover.

When to target

Seasonality

Peak fishing May–October. Winter slows but bay populations are resident year-round — fish slower and deeper in cold months.

When they bite

Tide preference

Incoming through slack-high — they ride the tide into the shallow flats

Time of day

Dawn and dusk strongly preferred; some night activity around lighted docks

Pressure

Stable

How to identify

Olive-brown back, dark spots scattered (not in rows like sand bass), 3 dorsal spines, pectoral fin extends past anal fin origin (key vs. sand bass), more compact body than calico

No catalog spots currently list this species — audit pending.

Seasonality

When to target

Peak fishing May–October. Winter slows but bay populations are resident year-round — fish slower and deeper in cold months.

Table fare

If you keep it

Good — mild, white, flaky. Within bag limit and slot, very edible. Most are released for their sportfishing value.

⚠ Safety & handling

Before you grab it

Sharp gill rakers and dorsal spines — use grippers when unhooking. No toxicity.

Common mistakes

What anglers get wrong

Often called "sand bass" inside the bay — they're a separate species. Check the pectoral fin length and the spot pattern (scattered vs. barred).

Did you know

Spotted bay bass are catch-and-release champions — they grow FAST (8" in their first year) and tolerate handling well. The Mission Bay catch-and-release tournament fleet routinely accounts for 200+ fish/day boats.
