They flop and slip and make sweet love on the sand under the full moon’s light.
Grunion — unique little fish found only in Southern California and down south in Baja — are little marine critters that mate on the sand when the waves wash them to shore. When the grunion are running, people in the know show up in the dark of night to wait and watch, some ready with buckets to collect the critters to eat, when catching them is allowed.
“It’s a cool California thing,” said Jim Serpa, who for 20 years ran a grunion night at Doheny State Beach while he was supervising rangers, before retiring a few years ago.
The grunion season officially kicked off early March, and the next run is expected Saturday, March 17 through Tuesday, March 20.
So grab your flashlights, beach chairs and, if you don’t mind staying up late, get ready to watch them run.
Serpa offered tips on why they run, the best times to go, and interesting tidbits about the fascinating fish:
1. Why do grunions wash up on shore?
They are mating. They have to mate at night, when the tide is at its highest around a full moon. They want to be on the sand so the eggs have a long time to incubate, Serpa said. They live off shore when they are not running — they just don’t come to shore unless it’s spring or summer.
Each female lays 2,000 to 3,000 eggs. They have a short life — only about five years max — and get to be about six inches long. The females bury themselves up to the fins, deposit their eggs and the males deposit the milt right there. When the wave comes by, the sand closes it up. The eggs stay buried in the sand for 10 to 14 days. The wave and surge jostling helps them hatch.
2. Find a beach they like
Some beaches, they don’t run on. It all depends on what’s underneath, if it’s good sand, Serpa said. They don’t like gravelly beaches. You might not see them in one spot, but a mile farther, they might be going like gangbusters. At Doheny, it’s rocky underneath but once you get on the beach, it’s sand. It’s perfect for them.
“When I was growing up, we always went to La Jolla. Any beach like that — Huntington, Crystal Cove and there’s a great beach up by the Cabrillo Aquarium in San Pedro. Malibu would be a great beach for it,” he said. “You want a beach that is a real gradual, you don’t want a shore break beach where the waves drop and dump.” Serpa said they seem to like Doheny, perhaps because the jetty acts as a shelter. Cabrillo offers something similar.
3. Go early in the season
They always run really good in the early part of the season, in April and May, Serpa said. As we get further into the year, it’s more hit or miss.
April and May, however, is the closed part of the season — so it’s just for watching, no catching.
4. Don’t spook the scouts
Try and let them come up and start their full run before you start annoying them and shining bright lights on them. “I don’t know that there’s been any real scientific data on it, but what we noticed, they always run better if you start letting them run for a while,” Serpa said.
5. Know the tides
You always want to go right before the peak of the high tide. They don’t run until that peak happens, Serpa said. If they do run before that, they have a chance of their eggs washing out.
“A lot of people, they see the run at midnight and say ‘let’s go at 10,'” Serpa said. “Kids are waiting and two hours later they haven’t run and they say, ‘let’s get out of here.'” The good time is the peak and the people just came too early. Timing is critical.
6. Watch the birds
“We would go out an hour or two before the peak of the high tide,” Serpa said. “If the birds were lined on the beach waiting, that means the grunions were in the shallows and they are ready to run and (the birds) know it.”
7. Tips for taking
You’ll need a fishing license if you are 16 or older. And don’t take anything you won’t use. You can only take with your hands — no scooping devices. That allows for more grunion to go back and helps the resources to stay healthy, Serpa said.
8. Don’t get soaked
Keep your eyes on the waves, Serpa warned. People get so absorbed with picking up the grunions, and then the wave comes and they get soaked.
9. Are they tasty?
If you ask me, I’d say no, Serba said. “But plenty of people like them,” he said. “A lot of people fry them up, the whole thing. Other people gut them.”
10. Fishing is good during grunion runs
Local fishermen know that. There’s halibut during that time, Serpa said. He’s seen huge halibut taken off the beach during grunion run nights.
11. Are the waters sharkier during grunion runs?
Nobody has done a study on that, Serpa said, but putting two and two together, it might be a good guess. “Juvenile sharks love grunion,” he said. “So offshore might be a place to see (sharks).”
12. What should we bring to a grunion run?
A flashlight, chair so you can sit while you’re waiting, a bucket to put your grunion in and a fishing license if you are planning to take them. A jacket to stay warm is always a good idea.
