Researchers are hoping to learn more about the pismo clam to revive the sea creatures’ populations, like the abalone once found abundantly off California coast.
The hunt was on for signs of the once-abundant pismo clams, tiny treasures that bury themselves below the sandy surface.
Sarah Haas, a UCI student, checks to see if she has found a Pismo clam as she rakes the sand at Huntington Beach on Wednesday, April 13, 2022. She volunteered to help local marine advocate Nancy Caruso to document the number, size and weight of Pismo clams, which were once abundant along the coast.

. “There’s some, but they are really hard to find. People are nostalgic about them, like the abalone.” The clams’ demise is thought to have come from a combination of recreational fishing pressure – thousands of mature clams being removed each weekend, millions in a season, as well as possible impacts from the 1983 El Nino storms that ravaged the coast, said Sean Bignami, associate professor of biology and marine lab director at Concordia University in Irvine, which is involved in the collaboration.
Taking the smaller clams that are not yet at reproductive age means their numbers won’t have the chance to further multiply. Finding just the right contraption to hold a pismo clam in a lab setting was a struggle. It needed to be held upright, but not so tight that the shells couldn’t open slightly to feed.
“We’re kind of writing an empty roadmap here. They obviously live in sand, they are hard to count and calculate. One of the steps we’re trying to crack – do we even need sand?” she said. “This is a tiny piece in a huge puzzle. We don’t have the total picture yet, but we can start from there.”
