Fish Consumption Advisories in California: What’s Safe to Eat & Where

Quick answer: Usually yes — but California issues location-specific consumption advisories for mercury and PCBs (how many servings per week are safe, with stricter guidance for women 18–49 and children), and emergency closures for domoic acid in crab, clams and some finfish. Safety depends on the species, the location and who’s eating it, so check the advisory for your specific water before the fish hits the pan.

Catching the fish legally is half the question. Whether to eat it — and how often — is the other half, and it’s governed by a system most anglers never hear about until a crab closure makes the news.

Who issues what

The two kinds of “don’t eat that”

1. Chronic contaminant advisories (mercury, PCBs). These never close a fishery — they tell you how often you can safely eat what you catch. Guidance is split into two groups: women 18–49 and children 1–17 (strict) and everyone else (looser). The pattern: big, old predators carry the most mercury; sediment feeders near urbanized bays carry PCBs. The same species can be “2 servings a week” on one stretch of coast and “do not eat” in a specific harbor.

2. Acute biotoxin events (domoic acid, PSP). These do close fisheries — crab season delays, razor clam closures, the annual mussel quarantine (typically May–October for sport-harvested mussels). Domoic acid is produced by algal blooms, concentrates in crab viscera and shellfish, and is not destroyed by cooking. When a zone is closed, there is no safe preparation.

What OEHHA actually says, in numbers

OEHHA’s coastal and bay advice comes to 322 guidelines across 11 zones and 64 species, each one split between two audiences. The scale is the point: this is not a handful of warnings about swordfish, it is a per-species, per-water-body table that CDFW’s regulations booklet does not reference at all.

The statewide default — California coastal waters with no site-specific advice. Even out on the open coast, for women 18–49 and children 1–17, OEHHA lists five DO NOT EAT categories:

• China rockfish
• Black and yellow rockfish
• Gopher rockfish
• Copper rockfish
• Sharks (as a category)

Every one of those rockfish is legal to keep under the 10-fish RCG aggregate. Both things are true at once, and only one of them is in the booklet.

Bays are stricter, and they are where people fish from shore. San Diego Bay alone carries eight DO NOT EAT entries for the sensitive audience, including barred sand bass, spotted sand bass, yellowfin croaker, shiner perch, topsmelt, Pacific chub mackerel and two sharks. San Francisco Bay adds striped bass, white sturgeon, sharks, shiner perch, topsmelt and Pacific sardine, plus a blanket “all fish and shellfish” for the Lauritzen Channel.

Santa Monica Pier to Seal Beach Pier — the densest stretch of pier fishing in the state — lists white croaker, black croaker, Pacific barracuda, barred sand bass and topsmelt as DO NOT EAT for women 18–49 and children.

Lingcod and vermilion rockfish are one serving a week on the open coast for that audience, against a CDFW bag limit of two and ten respectively.

Ocean species with recurring acute advisories

• Dungeness and rock crab — domoic acid delays and zone closures most falls and winters.
• Sport-harvested mussels — statewide quarantine every summer.
• Razor clams — domoic acid closures in the north.

None of this is a reason to stop eating your catch — most California ocean fish, most places, are healthy food, and OEHHA also flags the species that are particularly high in omega-3s and worth eating more of. It is a reason to check your specific spot and the person eating it.

Advisories, in the same app as the regulations

The problem with advisories is that they live on a different website than the fishing regulations, organized by a different agency’s logic. Creel merges them: active CDPH advisories surface directly in the app, next to the season and limit data for your region, refreshed daily. When a domoic acid zone opens or a viscera advisory drops, it shows up where you’re already looking — before the crab pot goes down, not after dinner.

Health advisories are exactly the regulations you don’t want to learn about retroactively. When in doubt, check CDPH’s current advisories or call the shellfish information line at (800) 553-4133.
