By now you have googled "grunion" and know that it is a little fish, a smelt, I suppose. Believe it not, you are restricted by state law to catching grunion by hand.
Yep, you can only take grunion when they come up on the beach to spawn. They come in grunion runs at certain high tides at certain phases of the moon that are predictable. Then you go wait on the beach for the right wave. And...if you are lucky enough to be at the right beach, they don't come to all beaches all at once...one wave will bring in millions of dancing little smelt. Well they are not dancing...they are mating, they just look like they are dancing.
The male wraps himself around the female and she stands on her tail (I'm not kidding) and burrows tail first into the sand and deposits the eggs,just fertilized.
His life's work is done: Her life's work is done. Grab 'em by hand and put as many as you can catch in a sack. Taint easy, they don't just sit there. The wiggle, they bounce.
And you gotta be quick. The next wave washes them all out to sea again. Grunion run over.
You can take 'em home, but the romantic thing to do is pan fry 'em whole on a camp fire on the beach. You eat 'em whole too. They are tiny, finger sized, and crunchy.
But the most fun about a grunion hunt is that you rarely ARE on the right beach at the right time. You are there with your sweetie and a bunch of beach loving friends in skimpy suits in the middle of the night...in full moonlight remember...
I am 82, and been on a LOT of grunion hunts and have only seen the run about three times. I think I have caught ONE grunion. (Just enough to prove they exist. They are not like snipes.)
And wouldn't this make a neat entry for my journal. Thanks for asking.
