Pismo clams can be harvested with a valid fishing license. Note that almost no legal sized clams can currently be found in the Pismo Beach area. All undersized clams must be immediately reburied in the area where they were found. In all other counties, the season is open year-round. As Pismo clams recover from a decades-long population decline, only a small percentage have reached legal harvest size, with almost all clams found being too small to harvest. Wildlife officers have issued hundreds of citations for possession of undersized clams and seized thousands of undersized clams in the past few years.
Pismo clam poaching can be reported via CalTIP. Additionally, the San Luis Obispo Coast District offers an overview video on the Pismo Clam population, including instructions for reburying clams.
A : Yes. A : In the past, it was relatively uncommon for clams to become unburied at Central Coast beaches and in the Monterey area. Some of these clams perish from drying out in the sun or being eaten by birds, but many rebury and survive, according to reports from California Polytechnic State University, San Luis Obispo Cal Poly.
The smaller clams seem to unbury more easily, but they also rebury easier than the bigger ones. The results did not show that any of these factors likely contributed to clams unburying. Cal Poly is keeping an eye on the unburied clams and may do further testing. Pismo clams can be harvested with a valid fishing license. Note that almost no legal sized clams can currently be found in the Pismo Beach area.
All undersized clams must be immediately reburied in the area where they were found. In all other counties, the season is open year-round. The sand is also fine without too many rocks. Scientists are unsure how long it takes a clam to reach legal size; estimates range from 10 to 14 years to grow to 4. In some places in Southern California, legal-sized clams can still be found, but researchers are hesitant to say exactly where for fear of attracting poachers.
Cal Poly scientists have been investigating the disappearance of the clam at Pismo Beach since , when the City Council provided funding for preliminary surveys. Around , came somewhat encouraging news. This phenomenon, called broadcast spawning, is common in other marine species, including many fish such as tunas, sea urchins and abalone : Young animals all sort of show up at once.
Most eggs and larvae get eaten by predators, but sometimes huge numbers beat the odds and survive, leading to mini population booms. Did these pulses signal a rebound for the beloved species? Or would the same factors that nearly wiped out the Pismo clam strike again? On that fall day in , Marquardt and her crew continued their census. After almost an hour of work, the teams had excavated several foot-long trenches. Some scooped sand on to the wagons topped with chicken wire while others dumped buckets of water to melt away the sand.
Finally, the teams started to strike gold just a few inches deep: dozens of the banded brown shells of the Pismo clam. When a group of beachgoers wanted to know what was going on, Marquardt stopped digging to explain.
Just as one conversation ended, another seemed to begin with passersby young and old. Such is the magnetism of the Pismo clam. When Marquardt spotted a clam, the conversations stopped. This was a bean clam, which can resemble a young Pismo in size and color patterns. Most Pismos are sort of beige with darker brown or purplish bands that generally correspond with age, like the rings of a tree trunk. Some shells have long purple stripes radiating from hinge to opening. She shrugged.
Another mystery on the list. Marquardt resumed digging.
