Creel Quick answer: California halibut must measure at least 22 inches total length to keep, and the season is open year-round statewide. The daily bag and possession limit is 5 fish in the Central and Southern regions. North of there — the Northern, Mendocino, San Francisco and San Francisco Bay regions — CDFW’s current regional pages list 2 fish, down from the 3 that most printed sources still quote. Pacific halibut is a different species with its own quota season, a 1-fish limit and no size minimum.
The 22-inch rule is simple. The details around it — bag limits that change at Point Sur, a lookalike species with completely different regulations — are where anglers get fined.
The rules

| Bag & possession — Central & Southern | 5 fish |
| Bag & possession — Northern, Mendocino, San Francisco, SF Bay | 2 fish |
| Season | Open year-round, statewide |
| Gear (angling) | Standard rod-and-line; spearfishing legal for divers |

The northern number is the one to check. Nearly every printed guide and blog post still says 3 fish north of Point Sur. CDFW’s own regional pages currently list 2, following the emergency regulation that reduced it. This is a good example of why a booklet printed in the spring is not a safe source in the autumn — and it is a $430-to-$485 mistake plus $71 to $82 for the extra fish.
Measure right, measure early
Total length means jaw tip to tail tip, mouth closed, fish flat. The mistakes that produce citations:
- Measuring curved. A fish bent on a hatch lid “gains” half an inch that disappears on the warden’s flat board.
- The “close enough” keeper. 21½ inches is not 22. Halibut shrink slightly after death, so a borderline fish measured generously at the rail can tape short at the dock.
- Filleting at sea. Fillet size requirements exist precisely so size limits stay enforceable — a fillet must retain skin and meet minimum fillet lengths. Simplest practice: keep halibut whole until you’re ashore.
Point Sur: the invisible line
The bag limit changes at Point Sur, Monterey County: 5 fish south, 2 fish north on CDFW’s current regional pages. If you fish out of Monterey or Santa Cruz, you’re in reduced-limit water even though “Southern California limits” dominate what you’ll read online. The line matters most for trailer boats that fish both sides in a season.
Don’t confuse it with Pacific halibut
Pacific halibut is a different fishery with nearly opposite rules: one fish, no size limit, strict quota-managed season (April 1 through December 31, 2026, or until the quota is reached), and its own gear restriction (one line, two hooks max). It’s mostly a far-northern California fishery. Keeping “a halibut” under the wrong species’ rules is a real and expensive mix-up around Point Arena and north.
One tap in Creel
Open Creel, tap halibut, and your region’s exact rule set is right there — the 22-inch minimum, whether you’re in 5-fish or 3-fish water, and the separate Pacific halibut card with its quota-season status, updated daily from CDFW. Cached offline, because the bite doesn’t wait for cell coverage.
Always confirm with CDFW before fishing — in-season actions (like a Pacific halibut quota closure) can change the rules overnight.
Frequently asked questions
How do you measure a California halibut?
Total length: from the tip of the lower jaw (mouth closed) in a straight line to the tip of the longest lobe of the tail, laid flat. Measure before it goes in the box — a 21¾-inch fish is a citation, and wardens carry tapes.
What's the difference between Pacific halibut and California halibut?
Two different species with different rules. California halibut (Paralichthys californicus) is open year-round, 22-inch minimum, bag of 5 south / 3 north of Point Sur. Pacific halibut (Hippoglossus stenolepis) is a larger northern species with a quota-managed season (April 1 – Dec 31 in 2026, or until quota), a 1-fish limit and no size minimum, mostly caught north of Point Arena.
Are California halibut good eating?
Among the best on the coast — mild, firm white fillets. Check CDPH consumption advisories for specific bays (some urban bays carry mercury or PCB meal guidance), but ocean-caught halibut is a staple table fish.
How old is a 22-inch California halibut?
Roughly 4–5 years old, which is around the age most females have spawned at least once — that is the biological logic of the 22-inch minimum: let fish reproduce before harvest.
