Shellfish PSP Monitoring

SITC Water Resources Program samples shellfish from Lone Tree Point for paralytic shellfish poisoning (PSP). Washington Department of Health, Shellfish Programs (WADOH-SP) provides  prepaid shipping via Greyhound bus, and sample analysis for PSP on the shellfish collected. Swinomish Water Resources Program provides staff time to collect samples. The shellfish beds at Lone Tree Point were chosen for regular monthly PSP sampling since Tribal members utilize these shellfish beds for subsistence and ceremonial shellfish uses. Ten (10) Butter clams are collected for analysis since Butter clams are the best indicator of potential PSP problems. Lone Tree Point typically does not have PSP problems and there has only been one PSP detection over the last 11 years at Lone Tree.
