The California halibut size limit is 22 inches total length. That minimum applies to every angler in every ocean water and bay in the state, recreational or commercial, and a fish shorter than that must go back in the water. The rule sits in Title 14, Section 28.15 of the California Code of Regulations.1Legal Information Institute. California Code of Regulations Title 14 Section 28.15 – California Halibut
How to Measure the Fish
Total length is the straight-line distance from the tip of the head, mouth closed, to the end of the longest tail lobe, with the fish lying flat on its side.2California Department of Fish and Wildlife. California Recreational Ocean Fishing Regulations – General Provisions Three details decide most borderline cases:
- Measure in a straight line. Running the tape along the curve of the body 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.
- Keep the mouth shut. The forward reference point is the tip of the head with the jaw closed.
If the fish looks close, let it go. The warden’s calibrated board is the one that counts, and a quarter inch is not worth the citation.
Make Sure It’s a California Halibut
The 22-inch minimum applies to California halibut (Paralichthys californicus). Pacific halibut (Hippoglossus stenolepis), which turns up occasionally in northern California waters, has no minimum size limit for recreational take.3Legal Information Institute. California Code of Regulations Title 14 Section 28.20 – Halibut, Pacific If you’ve landed a Pacific halibut, it can be any size, subject to its own separate bag rules.
Two features sort the species out. California halibut can have eyes on either side of the head, roughly split 50/50 between left-eyed and right-eyed fish; Pacific halibut always have eyes on the right. The upper jawbone on a California halibut extends past the eye, while on a Pacific halibut it reaches only to the front edge of the eye.4California Department of Fish and Wildlife. Nearshore Fishes If both species could show up where you fish, confirm which one you’re holding before you decide whether the 22-inch rule applies.
How Many You Can Keep
Once a fish clears 22 inches, the daily bag limit depends on where you caught it. The dividing line runs 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. Even with fish frozen at home from earlier trips, you can’t possess more than a day’s limit at any one time. The season is open year-round.5California Department of Fish and Wildlife. Current California Ocean Recreational Fishing Regulations
Filleting Halibut on the Boat
California’s general rule is that fish with a size limit can’t be filleted aboard a vessel unless regulations specifically set a fillet size for that species.6Legal Information Institute. California Code of Regulations Title 14 Section 27.65 – Filleting of Fish on Vessels For California halibut, Point Arena in Mendocino County splits the state:
- South of Point Arena: filleting on board is allowed. Each fillet must be at least 16¾ inches long, the skin must stay entirely intact, and the fillet can’t be cut into halves. One lengthwise midline cut is permitted as long as the two pieces remain joined for at least two inches at one end.
- North of Point Arena: no filleting on a vessel. The fish must come ashore whole so an officer can verify the 22-inch minimum.
The skin-intact requirement lets wardens identify the species and estimate the length of the original fish. Skinning a fillet defeats both and turns a legal piece of fish into a violation.
What a Short Fish Costs You
Most California fishing violations are misdemeanors.7California Legislative Information. California Fish and Game Code Section 12000 Keeping an undersized halibut, exceeding the bag limit, or breaking the fillet rules all qualify. On top of fines, a judge can order forfeiture of any gear used in the offense, including rods, tackle, and nets, and for more serious offenses the vessel itself.8California 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 measuring boards. If a halibut doesn’t clearly exceed 22 inches, release it.
