Abstract

Starting in November of 2012, there was an unusually long PSP biotoxin geoduck closure in the Southern Salish Sea (Vashon & Bainbridge Islands). HABs in the area have usually occured during warm sunny months. The weekly geoduck PSP samples remained over the closure limit even though mussel samples showed little or no toxins. There seemed to be a PSP migration from North to South. Individual geoduck gut contents were examined for cells or cysts but was inconclusive. A similar Winter closure occured eight years prior, pointing to possibe cyclic occurence.
