California Grunions are a fun fish to catch here in California.
If you’ve never seen a grunion run, just imagine a bunch of fish on the beach mating.
Unlike most people, I was exposed to the infamous Grunion Run later in life. Most people I talk to are first exposed when they are kids, running up and down the beach trying to grab before they make it back to the ocean.
There’s no reason you can’t have the same fun as an adult!
In this article, we’ll cover grunion facts, how to catch them, and how to turn them into delicious tacos.

Always check the CA Fish and Wildlife site to see the latest grunion run times.
Where to Catch California Grunion
You’ll be able to find grunion on beaches that are sandy with a gradual slope. They range from Baja to San Fransico.
They are most abundant between Baja and Pt. Conception. They are a schooling fish that tends not to migrate vast distance but is rather a home-body.
Grunion Run Beaches
There are too many spots to name, but if you’re looking for grunion, it’s best to find a beach near you that has the right characteristics for them to night spawn.
This means relatively flat sandbanks and soft sand. I’ve gone out to places where I thought there should be grunion only to be skunked. When I drove down a mile to a better section of the beach, they were everywhere.
If you can’t find them, move to a new location!
Here are some areas that seem to have a lot of grunions:
- San Diego (La Jolla)
- Manhattan Beach
- Newport Beach
- Playa Del Rey (Marina Del Rey and Venice)
Grunions have unique mating habits.
Here’s how the process unfolds:
- The females ride a wave into shore with one to eight males with her.
- She’ll get as far as she can up the beach.
- She’ll then bury herself tail first in the sand.
- If a male is touching her she’ll release her eggs in the sand.
- The male or males will then release their sperm on her and fertilize the eggs.
- The males will go back into the water and she’ll free herself and join them.
A female will do this ritual a few times a season (between four and eight). It’s estimated that she’ll lay between one thousand and three thousand eggs per season.
California grunion fishing is interesting in that you’re required by law to catch them with your hands.
That means no nets, tools, or traps (like digging a huge hole or fence in the sand).
How to Catch Grunion
It can be hard to grab them with your hand if you’re just going for their body.
To make it easier, try grabbing a handful of sand when you grab them. It tends to put pressure down on their body, pinning them to the sand and gives you a better grip. Throw it in your bucket or fishing cooler and catch more.
You’ll just have to strain out the sand and home or before you leave.
Apparently coastal Native Americans ate grunion a bunch. They knew what’s up!
I’ve heard about grunion tacos back in college, but it wasn’t until recently I decided to try it…
I’ve been missing out!
Before we hop into that recipe, let’s clean them.
How to Clean Grunion
The easiest way to clean grunion is to buy a pair of shears (scissors work too).
Here’s my step-by-step process:
- Squeeze them to release the eggs or sperm before cleaning. I do this in the sink.
- Cut the head of the grunion off with shears right behind the pectoral fins. Below is one that’ll work well.
- REDUCE HAND STRAIN: These micro tip snips are...
- ULTRA SHARP BLADES: These quality snips come with...
- SECURE, EASY TO OPERATE LOCK: These micro tip...
- Take the shears and insert one end into the anus.
- Cut up to where the head was.
- Use your finger to scoop out the guts.
- Repeat with all of your grunions.
- Take your thumb (the fleshy part) and rub the inside cavity to remove the black stuff. Do this under running water to make it easier.
- Repeat for all of your grunions.
- Store them in the fridge or freezer. You can dry them off with a towel if you want before storage.
- OPTIONAL: Some people like to scale them using a spoon or the edge of a knife. I find that the scales taste amazing fried so I leave them on.
How to Cook Grunion
Keep it simple.
- Heat up a cast iron skillet.
- Batter your cleaned grunion with egg, flour (panko, breading, etc), or no breading at all.
- Add some oil to your skillet and get it hot.
- Drop your grunion on there and cook each side for 1-3 minutes.
- Remove and use them as your protein for your tacos.
Another option is to just add some soy sauce or Maggie to non-battered fried grunion. Throw them over rice or vegetables and you got yourself some good clean eats right there!
