Creel Quick answer: Saturday, November 7, 2026 — the recreational season opens on the first Saturday in November. The daily bag limit is 10 Dungeness crab with a 5¾-inch minimum size, and traps require a Recreational Crab Trap Validation. But the calendar date is the least reliable part: domoic acid testing and whale-entanglement risk have delayed or restricted the recreational opener in most recent seasons, sometimes with only days of notice, and those delays land zone by zone rather than statewide.
The date
The California recreational Dungeness crab season opens on the first Saturday in November. In 2026 that is Saturday, November 7.
It closes June 30 south of the Mendocino/Sonoma county line and July 30 north of it.
You will also see a completely different date reported for “crab season” every autumn — that is the commercial fishery, which runs on its own schedule and opens later. The two get conflated in headlines constantly. If you are dropping pots off a pier or your own boat, November 7 is your date.
The rules
| Rule | |
|---|---|
| Opens | Saturday, November 7, 2026 (first Saturday in November) |
| Closes | June 30, 2027 south of the Mendocino/Sonoma line · July 30, 2027 north |
| Bag limit | 10 Dungeness crab per person per day |
| Size | 5¾-inch minimum, measured across the widest part of the shell |
| Gear | Traps, hoop nets, crab snares, or by hand |
| Trap validation | $2.98 Recreational Crab Trap Validation, required for traps only |
| Licence | Sport fishing licence — not required on a public pier |
Rock crab is a different species with different rules: 35 per day, 4-inch minimum, open year round. People pull both out of the same pot and apply the wrong limit to whichever one they were thinking about.
The calendar date is the least reliable part
In most recent seasons the November opener did not happen cleanly, and it is worth understanding why, because the two causes are unrelated and behave differently.
Domoic acid. A neurotoxin produced by Pseudo-nitzschia blooms, it accumulates in crab viscera. CDFW and CDPH test through the autumn and delay any zone that fails. Because it is measured by zone, the coast can open in pieces — Half Moon Bay open, Bodega Bay closed, two weeks apart.
Whale entanglement. The Risk Assessment and Mitigation Program watches for humpbacks, blue whales and leatherback turtles still feeding in the grounds. If they are there when the season would open, CDFW can delay it or restrict trap gear. This one tends to hit the end of the season too, with spring trap restrictions that arrive before the calendar close.
Either one lands with days of notice, in a specific zone, by an announcement posted on a CDFW page. This is the single most common way a Californian shows up at a ramp on opening morning with a truck full of pots and no legal fishery.
Do not confuse the season with the advisory
An open season is not a statement that the crab is safe to eat, and a health advisory is not a closure. They come from different agencies and can be in force at the same time.
Domoic acid concentrates in the viscera — the “crab butter” — far more than in the meat. That is why advisories frequently tell you to eviscerate the crab and discard the cooking water rather than closing the fishery. Following the season and ignoring the advisory is how people get sick during a perfectly legal opener.

Get the delay before you load the truck
Creel scrapes CDFW’s in-season change feed and CDPH’s shellfish advisories daily, and pushes the ones that affect your region. Set a watch on Dungeness crab and you get a reminder the morning before November 7 — and, more usefully, a push the moment your zone gets delayed instead of the one you happen to read about.

Frequently asked questions
When does crab season open in California in 2026?
Saturday, November 7, 2026 for the recreational fishery — the season is set as the first Saturday in November. The commercial season runs on its own schedule and opens later, which is why you will see two different "crab season" dates reported every autumn. If you are dropping your own pots or hoop nets off a pier or a private boat, November 7 is your date, subject to any delay CDFW announces for your zone.
Why does Dungeness crab season get delayed in California?
Two independent reasons. Domoic acid, a neurotoxin produced by algal blooms, accumulates in crab viscera; CDFW and CDPH test through the autumn and delay any zone that fails. Separately, the Risk Assessment and Mitigation Program watches for humpback and blue whales and leatherback turtles still feeding in the fishing grounds, and can delay the opener or restrict trap gear to prevent entanglement. Either can move a single zone while the rest of the coast opens on time.
How many Dungeness crab can you keep in California?
Ten per person per day, with a minimum size of 5¾ inches measured across the widest part of the shell in front of and excluding the points. That is the recreational limit statewide. Rock crab is a separate species with a much larger limit — 35 per day at a 4-inch minimum — and the two are easy to confuse in a pot.
Do I need a validation to use a crab trap in California?
Yes. A Recreational Crab Trap Validation costs $2.98 in 2026 and is required for anyone using a crab trap in ocean waters, on top of a sport fishing licence. Hoop nets and crab snares do not require it. Traps also have to carry surface buoys marked with your GO ID, and there are destruct-device and service-interval rules designed to stop lost gear from ghost-fishing.
Is it safe to eat Dungeness crab right now?
Check before you cook. Domoic acid concentrates in the viscera — the "crab butter" — far more than in the meat, which is why health advisories often say to eviscerate the crab and discard the cooking water rather than closing the fishery outright. CDPH issues these advisories independently of whether the season is open, so an open season is not by itself an all-clear.
When does California crab season end?
The recreational season runs through June 30 south of the Mendocino/Sonoma county line and through July 30 north of it. In-season closures can end it earlier in any zone, and trap restrictions imposed for whale entanglement often arrive in spring, before the calendar close.
