Spearfishing Legal Size Limits: San Diego Scorefish Species Reference
California’s spearfishing regulations exist to protect fish populations and ensure sustainable diving. Whether you’re working the kelp forests off La Jolla, Point Loma, or the reefs near Torrey Pines, knowing the legal minimum size for each species isn’t optional—it’s essential. Undersized fish mean citations, fines, and lost diving privileges.
This guide covers the most commonly targeted scorefish species in San Diego waters and their current legal minimums. Regulations change, so always cross-check with the California Department of Fish and Wildlife (CDFW) before your dive.
Kelp Bass (Paralabrax clathratus)
Legal minimum: 12 inches total length
Kelp bass are the workhorse of San Diego spearfishing. You’ll find them around the kelp forests of the Coronado Islands, Point Loma, and the shallow reefs off Ocean Beach. They’re aggressive, abundant, and forgiving for newer spearfishers. A solid 12-incher is table-ready; anything larger is a bonus.
Measure from the tip of the mouth to the end of the tail fin. No exceptions. Many divers carry a waterproof measuring tape in their BC pocket—worth the minimal space.
Calico Bass (Paralabrax sexfasciatus)
Legal minimum: 12 inches total length
Calico bass inhabit the same rocky reefs and kelp zones as their kelp bass cousins, but they’re often deeper and more elusive. The sandstone reefs around La Jolla Shores and the drop-offs near Sunset Cliffs hold good populations. Calicos are prized for their fighting ability and firm flesh.
The 12-inch minimum applies year-round. During summer (June–September), calicos are more active and easier to approach when water clarity peaks.
Barred Surfperch (Amphistichus argenteus)
Legal minimum: 7.5 inches total length
Surfperch aren’t scorefish glamour, but they’re plentiful in San Diego’s sandy shallows and kelp edges. The beaches around Mission Beach and the shallow zones off Coronado often hold good numbers. At 7.5 inches, they’re smaller than bass, but they’re quick, so accuracy matters.
Scorpionfish (Scorpaena spp.)
Legal minimum: 5 inches total length
California scorpionfish—sometimes called sculpin—hide in rocky crevices and reefs throughout San Diego. The Point Loma reefs and the offshore pinnacles near the Coronado Islands hold them. They’re not a primary target, but they’re edible and fun to hunt. Watch your hands during processing; their spines are venomous and sharp.
Sheephead (Semicossyphus pulcher)
Legal minimum: 12 inches total length
California sheephead are iconic San Diego fish: males are bold red and black, females are pink and white. They’re territorial, predictable, and present year-round around rocky structure. The reefs off Point Loma and La Jolla are prime territory. Sheephead can be tricky to approach—they’re smart—but a well-placed shot is rewarding.
Note: Only males (red and black) may be taken during the open season. Females (pink and white) are protected year-round. Misidentification is a common violation.
Sennet/Needlefish (Strongylura exilis)
Legal minimum: 12 inches total length
Sennet are fast, aggressive hunters you’ll see in shallow San Diego waters, especially around kelp beds and near structure. They’re not a primary spearfish target, but they’re legal and worth taking if the opportunity arises. Their long body makes measuring straightforward.
Cabezon (Scorpaenichthys marmoratus)
Legal minimum: 12 inches total length
Cabezon are bottom-huggers found in rocky reefs and kelp forests. They’re less common than bass in San Diego, but they’re legal and good eating. The deeper rocky zones off Torrey Pines occasionally yield them.
Opaleye (Girella nigricans)
Legal minimum: 9 inches total length
Opaleye are herbivorous and peaceful, making them easier to approach than bass. They’re found around kelp forests and rocky reefs throughout San Diego. The 9-inch minimum is smaller than bass, so younger divers often target them for confidence-building.
Critical Compliance Points
Measurement matters. Always measure total length (tip of mouth to tail fin tip). A fish that looks “close enough” to 12 inches may not be—and CDFW officers check. Carry a measuring device.
Bag limits apply. California enforces daily bag limits on most scorefish species. Kelp and calico bass combined: 10 fish per day. Sheephead: 5 fish per day. Check current limits before diving.
Seasonal closures exist. Some species have restricted seasons. Sheephead, for example, has a closed season during spawning. Verify the current year’s calendar with CDFW.
Report violations. Poaching undermines San Diego’s fishery. If you see undersized fish being kept or other violations, report them to CalTIP: 1-888-334-2258.
Use Element to Plan Your Dive
Knowing size limits keeps you legal, but knowing conditions—water clarity, temperature, swell, and wind—keeps you safe and successful. Check Element before your spearfishing trip to dial in the best dive window and target the species most active in current conditions.
