Kelp Bass
Calico bass — as most anglers call them — are the defining inshore fish of the eastern North Pacific kelp forest, ranging from Baja California north to the Pacific Northwest coast.
Brown-to-olive bodies patterned with white and yellow blotches let them vanish into the kelp canopy, and their instinct to dive back into that tangle the moment they're hooked is what makes them worth chasing.
Scientific Name: Paralabrax clathratus
Also known as Calico Bass, Bull Bass, Rock Sea Bass, Checkerboard Bass
- Brown to olive-green body covered in a calico patchwork of black, white, and olive blotches — the pattern that earns the name 'checkerboard bass' — with rows of rectangular white spots along the back and multicolored mottling on the belly.
- Light yellow spots scattered across the head; the belly mottling is a quick separator from similar-looking grouper relatives when the fish is in hand.
- Spawning males develop a visible orange flush on the chin and lower jaw — a useful field marker during late spring and summer.
- Most fish run 1–4 lbs; anything over 5–6 lbs is a quality fish, and a 10-pounder is a rare, career-level catch. Maximum size approaches 28 inches and 15 lbs.
What to know
Habitat Distribution
- Native to the eastern North Pacific from Baja California, Mexico, north to the Pacific Northwest coast — the bulk of the fishery sits south of Point Conception, where kelp forests are densest and water temperatures most suitable.
- A nearshore kelp-forest specialist, most commonly found in the top 6–65 feet of water, though larger fish push deeper and can be found to around 165 feet.
- Rocky reefs, bays, estuaries, and man-made structure — piers, breakwalls, shipwrecks, oil platforms — all hold fish wherever natural kelp is absent or sparse.
Specific Spots
- Feeding fish position on the up-current, seaward edge of a kelp bed — just inside the outer canopy where baitfish get funneled past and the bass can dart into open water and retreat to cover.
- Shaded pockets, deep holes, and undercut ledges within the kelp hold fish through midday when light penetration is high and the fish pull back from exposed edges.
- Bigger fish tend to sit lower in the water column than smaller ones — working baits and jigs along the base of kelp stalks and rocky structure rather than through the upper canopy is the adjustment that separates quality fish from schoolies.
Kelp Bass FAQ
Answers from onWater's species guide.
What are the best lures and bait for Kelp Bass?
Live anchovies and sardines are the benchmark bait, fished under a float near the kelp canopy or free-lined into structure, they produce when artificials won't.
What do Kelp Bass eat?
Anchovies, sardines, and squid make up the bulk of the adult diet, live anchovies and sardines fished near the kelp canopy are the most consistent bait, and soft-plastic swimbaits in baitfish profiles work because they match the same forage.
Where do Kelp Bass live?
Native to the eastern North Pacific from Baja California, Mexico, north to the Pacific Northwest coast, the bulk of the fishery sits south of Point Conception, where kelp forests are densest and water temperatures most suitable.
