Recreational harvest of marine algae for personal use is permitted in California. Those harvesting for personal use must abide by regulations governing the recreational harvest. The daily bag limit for recreational harvesters of marine algae is 10 pounds wet weight in the aggregate. Recreational harvesters are prohibited from harvesting or disturbing eelgrass (Zostera species), surfgrass (Phyllospadix species), and sea palm (Postelsia palmaeformis).
Marine protected areas, marine managed areas, special closures and state marine parks may prohibit cutting or harvesting. Marine protected area boundaries extend up to the mean high tide line.
