Calico Bass (Kelp Bass): How to Hunt California's Most Common Reef Fish

The Fish That Teaches You How to Dive

Ask any experienced California diver what their first spearfishing kill was, and the answer is almost always the same: calico bass. Also called kelp bass, these fish are the backbone of Southern California reef diving. They are everywhere, they are cooperative, and they are just challenging enough to teach you the fundamentals of reef hunting without punishing every mistake.

Calico bass (Paralabrax clathratus) are a member of the sea bass family and are found from Central California to Baja Mexico, with the highest densities in the Southern California kelp forests. They are handsome fish — mottled brown and olive with pale spots that give them a calico pattern, hence the name. They are also excellent table fare, with firm white meat that rivals any other bass species.

Habitat and Behavior

Calico bass are structure-oriented fish. They are almost always found in or around kelp, rocky reefs, artificial structure like pier pilings and breakwaters, and anywhere that provides cover and a food source. They are ambush predators that sit in the kelp canopy or along reef edges and dart out to grab small fish, shrimp, and crabs.

They hold at every depth from just below the surface down to 100 feet or more, but the sweet spot for divers is 15 to 40 feet — the heart of the kelp zone. You will find them hovering in kelp stringers, tucked against boulders, sitting under ledges, and cruising the edges where kelp meets open water.

Calicos are most active during warmer months (May through November) when water temperatures are in the mid-60s and above. In winter, they become more lethargic and hold tighter to structure, but they are present year-round.

Regulations

Minimum size: 14 inches total length. This is important — calico bass look bigger in the water than they actually are, and it is easy to shoot an undersized fish if you are not careful. When in doubt, let it go.

Bag limit: 5 fish per day. There is no closed season. Spearfishing is a legal take method. Check for MPAs at your dive site. Review the current California regulations before heading out.

How to Hunt Calico Bass

Finding Them

If you are in kelp, you are in calico bass territory. Start by snorkeling over the kelp canopy and looking down through the stringers. Calicos often sit in the mid-canopy, hovering between the kelp fronds at 10 to 20 feet. They blend in well against the brown and green kelp, so look for the slight movement of a fin or the distinctive mottled pattern.

On rocky reefs without kelp, scan the tops of boulders, the edges of ledges, and the mouths of crevices. Calicos tuck into structure and hold there, waiting for food to pass by. The edges where reef meets sand are also productive — bass patrol these transition zones looking for prey.

The Approach

Calico bass are moderately wary but far more forgiving than pelagic fish. A slow, calm descent toward a fish sitting on structure will often get you within range. Avoid rapid movements and do not swim directly at the fish — angle your approach and use the kelp or reef as cover.

One effective technique is to descend into the kelp and hang motionless. Calicos are curious and will often drift closer to investigate a still diver. Let the fish come to you rather than chasing it through the kelp, where you will spook everything in sight.

If a calico spooks, do not chase it. Mark the spot mentally and circle back in a few minutes. They do not travel far when disturbed and often return to the same holdout spot within minutes.

Shot Placement

Calicos are thick-bodied fish relative to their length, which works in your favor for shot placement. The standard target — behind the gill plate through the spine — works perfectly. Because most calico shots happen at close range (3 to 6 feet) in and around structure, a pole spear or short to mid-length speargun (75 to 90 cm) is the ideal weapon.

Be aware of what is behind the fish. Shooting into rock can damage or lose your shaft. When possible, take the shot when the fish is positioned over sand or with open water behind it.

Best Spots in California

Calico bass are abundant everywhere there is kelp or rocky structure in Southern California. San Diego (Point Loma, La Jolla outside the reserves, Mission Bay jetties), Orange County (Crystal Cove, Dana Point, Laguna Beach outside MPAs), Los Angeles (Palos Verdes, Malibu, Leo Carrillo), and the Channel Islands all hold strong populations.

Catalina Island is particularly good for calico bass. The clear water and extensive reef structure around the island hold large fish, and the visibility makes it easier to spot and approach them. The back side of Catalina in the kelp beds is classic calico territory.

Gear

Calicos do not require heavy gear. A polespear (6 to 7 feet with a paralyzer or single prong tip) is perfect for reef calicos and helps you learn to get close. A short to mid-length speargun (75 to 100 cm) with a single band is more than enough. A standard flopper tip is fine — no slip tips needed for fish in this size range.

Gloves are helpful when working in kelp and around rocky structure. A stringer or catch bag is all you need to secure your fish.

Cleaning and Cooking

Calico bass is underrated as table fare. The meat is firm, white, and mild — similar in quality to striped bass or black sea bass on the East Coast. The fillets are not huge, so plan on keeping a few fish for a meal.

Pan-fried is the classic preparation. Season fillets with salt, pepper, and garlic, dredge lightly in flour, and pan-fry in butter until golden. Serve with lemon. Simple, fast, and outstanding.

Ceviche is another excellent option. Dice the fillets into small cubes, cover with fresh lime juice, and let it cure for 30 minutes. Add diced onion, tomato, cilantro, jalapeno, and avocado. Fresh calico bass ceviche is a post-dive tradition for many Southern California divers.

Why Calicos Make You a Better Diver

Calico bass are the training ground for everything that comes next. Hunting them teaches you to read structure, approach fish without spooking them, manage your buoyancy in kelp, place accurate shots at close range, and handle your catch underwater. Every one of these skills translates directly to hunting bigger, more challenging species.

Do not overlook calicos because they are common. Master them first. The yellowtail and white sea bass will wait.
