Spearfishing Legal Zones in San Diego: Marine Protected Area Map and Rules
San Diego’s coastline offers world-class spearfishing opportunities, but you need to know exactly where you can hunt. California’s marine protected area (MPA) system has expanded significantly over the past decade, and fishing in the wrong zone can result in hefty fines. Here’s what every San Diego spearfisher needs to know before heading out.
The MPA Landscape in San Diego County
San Diego County has multiple Marine Protected Areas that restrict or prohibit spearfishing entirely. The California Department of Fish and Wildlife (CDFW) enforces these zones strictly, with penalties ranging from $250 to $1,000+ per violation.
The major MPAs affecting local spearfishing are:
San Diego-Scripps Coastal MPA – This stretches from the La Jolla Shores area north to the county line. Most of this zone is off-limits to spearfishing. You cannot take any fish here, period.
Point Loma Kelp Forest State Marine Recreational Area – Popular with divers, this area near Point Loma allows recreational diving but prohibits spearfishing and commercial activity.
Torrey Pines State Marine Reserve – This extends from Del Mar south to Torrey Pines. It’s a no-take zone. No spearfishing allowed.
Swami’s Reef to Encinitas – Portions of this reef system fall within restricted areas. You must verify exact boundaries before diving.
La Jolla Kelp Forest – While some areas near La Jolla are open, significant portions are protected. Stick to the outer reefs and confirm current boundaries.
Where You CAN Legally Spearfish
Not all of San Diego’s coast is off-limits. Several productive zones remain open year-round:
South of Point Loma to Border Field – The area south of the Point Loma Kelp Forest, including some spots near Coronado, offers legal spearfishing opportunities. Calico bass, halibut, and sheephead are common targets here.
Outer Reefs Past La Jolla – Beyond the restricted zones, the open ocean reefs and kelp forests remain productive. You’ll need a boat or be willing to do longer swim-outs, but the rewards are worth it.
Anza-Borrego Desert Tributaries – For freshwater spearfishing, certain inland reservoirs allow it, though regulations vary. Check CDFW guidelines for specific water bodies.
Offshore Islands – Santa Rosa and San Miguel Islands (when accessible) have open spearfishing zones, though weather and boat access are limiting factors.
Critical Rules Every Spearfisher Must Follow
Licensing and Permits You need a valid California fishing license and a spearfishing stamp. As of 2024, this costs around $17 for the stamp and varies for the license itself. Renew annually—expired licenses are not negotiable.
Gear Restrictions
- Speargun only (no pneumatic spearguns in some areas)
- Hand spear/trident allowed
- No explosives or poisons
- Shaft diameter typically limited to 0.5 inches
- Barbed or multiple-pronged tips required in some zones
Size and Bag Limits California enforces strict minimum sizes for each species. For example:
- Calico bass: 12 inches
- Sheephead: 12 inches
- Halibut: 18 inches
- Scorpionfish: 5 inches
Check the current CDFW Sport Fishing Regulations before every trip. Limits change seasonally and by zone.
Nighttime Restrictions Spearfishing is typically prohibited from sunset to sunrise. Plan your dives accordingly—this means early morning or late afternoon departures.
No Spearfishing from Piers or Boats (with limited exceptions) You must be a free diver or scuba diver. Fishing from a boat or pier requires different gear and different licensing.
Using the CDFW Map Tools
The California Department of Fish and Wildlife provides an interactive MPA map online. Before every trip:
- Visit the CDFW website and load the MPA map
- Zoom to your target location
- Check the zone type (Reserve, Recreational Area, etc.)
- Read the specific regulations for that zone
- Screenshot or print the map for reference
Don’t rely on memory or word-of-mouth. The boundaries are precise, and enforcement is real.
Seasonal Considerations for San Diego
Summer (June–August) – Peak spearfishing season. Water is clearer, but visibility brings more divers. Expect crowded reefs and warmer water. Target calico bass and sheephead.
Fall (September–November) – Excellent conditions. Fewer crowds, stable water temps, and good visibility. Sheephead and scorpionfish are active.
Winter (December–February) – Cold water and rough swells limit opportunities. However, halibut move into shallower waters. Dedicated hunters can find excellent winter fishing.
Spring (March–May) – Variable conditions. Early spring can be cold, but late spring offers warming trends and returning pelagics.
Final Checklist Before You Dive
- Current fishing license and spearfishing stamp
- Proof of valid MPA zone for your target area
- Dive computer and proper safety gear
- Buddy system (never dive alone)
- Cooler with ice for your catch
- Updated CDFW regulations printout
San Diego’s spearfishing opportunities are exceptional when you know the rules. Respect the MPAs, follow the regulations, and you’ll have world-class hunting on your doorstep.
