Expert Notes

The only truly Southern California oyster variety, Carlsbad Blondes are grown in suspended culture offshore in Agua Hedionda Lagoon. Their distinctive art deco appearance—glassy shells with jagged fans of white and purple stripes—is matched by their unique flavor profile. These oysters deliver a strongly briny punch balanced with sweet notes, complemented by refreshing overtones of melon and cucumber with a touch of alkalinity. The balanced briny-sweet character distinguishes them from Bay Area varieties, offering a taste that is definitively Southern California.

About the Farm

Carlsbad Aquafarm

Est. 1990

Carlsbad Aquafarm has been operational in the Agua Hedionda Lagoon since the 1950s, arising from a 1960s-era San Diego State University aquaculture research facility. It is the only sustainable oyster farm in Southern California, producing approximately 2 million pounds of shellfish annually.

Cultivation Method
suspended culture

History & Background

The Carlsbad Blonde is the only truly Southern California oyster variety. Carlsbad was a sleepy beach town midway between San Diego and Los Angeles before Lego decided to build a theme park there in the 1990s.

The farm benefits from nutrient-rich water circulating from the nearby desalination plant. The lagoon is part of the North San Diego County estuarine complex and features diverse wild marine life including birds, stingrays, sea bass, and octopus.

Did You Know?

  • The oyster has glassy shells with jagged fans of white and purple stripes reminiscent of an art deco light fixture
  • Carlsbad Aquafarm produces three variations: the very small Carlsbad Luna (the briniest), the Carlsbad Blonde (balanced), and the Del Sol (given a two-hour freshwater immersion to sweeten them)
  • The farm's buoys are white because sea birds frequently land on them, covering them with their droppings which also fertilize the area
  • Over 600 oysters hang from trays on a single buoy
