The legal size for California halibut is 22 inches total length. Anything shorter goes back in the water, whether you’re fishing from a pier, a skiff, or a party boat, and the rule applies in every ocean water and bay in the state under California Code of Regulations Title 14, Section 28.15.1Legal Information Institute. California Code of Regulations Title 14 Section 28.15 – California Halibut
How to Measure a Halibut Correctly
Total length means the longest straight-line distance from the tip of the head to the end of the longest lobe of the tail, with the fish flat on its side and its mouth closed.2California Department of Fish and Wildlife. California Recreational Ocean Fishing Regulations – General Provisions Three details cause most of the trouble:
- Measure in a straight line, not along the curve of the body. Bending a tape over the fish inflates the reading and a warden won’t accept it.
- Don’t pinch or spread the tail lobes to stretch the number. The tail sits naturally.
- The head tip is measured with the mouth shut.
If it looks borderline on your board, it will look borderline on the warden’s. The safer move is to release it.
Don’t Confuse California Halibut With Pacific Halibut
The 22-inch minimum is a California halibut rule. Pacific halibut, a different species occasionally caught in northern California waters, has no minimum size limit for recreational take and is subject to its own separate bag limits.3Legal Information Institute. California Code of Regulations Title 14 Section 28.20 – Halibut, Pacific
Two features tell them apart. California halibut can be left-eyed or right-eyed, roughly 50/50; Pacific halibut are always right-eyed. On a California halibut, the upper jawbone extends past the eye, while on a Pacific halibut the jaw reaches only to the front edge of the eye.4California Department of Fish and Wildlife. Nearshore Fishes Confirm the species before you apply any size rule.
Bag and Possession Limits
Once your fish clears 22 inches, how many you can keep depends on where you’re fishing. The state is split at an imaginary line running due west from Point Sur in Monterey County:1Legal Information Institute. California Code of Regulations Title 14 Section 28.15 – California Halibut
- South of Point Sur: five fish per day.
- North of Point Sur: two fish per day.
Possession limit equals one daily bag limit, so even frozen fish at home count against what you can hold at any moment. The season is open year-round.5California Department of Fish and Wildlife. Current California Ocean Recreational Fishing Regulations
Filleting on the Boat
California’s default rule bars filleting any species with a size limit aboard a vessel unless regulations specifically allow it.6Legal Information Institute. California Code of Regulations Title 14 Section 27.65 – Filleting of Fish on Vessels For California halibut, the rule splits at Point Arena in Mendocino County.
South of Point Arena, you can fillet aboard the boat, but each fillet must be at least 16¾ inches long with the skin left fully intact. You can’t cut a fillet into halves, though one lengthwise cut along the midline is allowed if the two pieces stay joined for at least two inches at one end.6Legal Information Institute. California Code of Regulations Title 14 Section 27.65 – Filleting of Fish on Vessels The skin-intact requirement exists so a warden can identify the species and estimate whether the whole fish met 22 inches. Skinning it defeats that purpose.
North of Point Arena, no filleting California halibut on a vessel at all. The fish comes ashore whole.
You Need a License First
Every person 16 or older must carry a valid California sport fishing license while fishing, even if you plan to release everything.7California Legislative Information. California Fish and Game Code Section 7145 Fishing without one is an infraction carrying a $100 to $1,000 fine for a first offense.8California Legislative Information. California Fish and Game Code Section 12002.2
Penalties for a Short or Over-Limit Fish
Most violations of California’s fishing rules are misdemeanors.9California Legislative Information. California Fish and Game Code Section 12000 Keeping a halibut under 22 inches, exceeding your bag limit, or filleting outside the allowed conditions all sit in that category. A judge can also order forfeiture of gear used in the offense, including rods, tackle, and nets, and for more serious offenses forfeiture can extend to the vessel.10California Legislative Information. California Fish and Game Code Section 12157
Wardens check fish at launch ramps, on the water, and at cleaning stations, and they carry calibrated measuring boards. If a fish doesn’t clearly exceed 22 inches on your own board, put it back.
