Invasion Description
1st Record: CA/Humboldt Bay (1963, in Crassostrea gigas, Ostrea conchaphila and Mytlius sp., probably trossulus, or hybrids with galloprovincialisand Mytilus californianus, (Chew et al. 1964a, cited by Carlton 1979; Katkansky et al. 1967, cited by Carlton 1979; Boyd et al. 2002)

Regional Impacts
| Ecological Impact | Parasitism | |
| Reduced condition factor was also reported in infected Pacific Oysters (Crassostrea gigas) in Humboldt, Yaquina, and Willapa Bays. However, no relation was seen between infection and mortality (Chew et al. 1965; Katkansky et al. 1967). | ||
| Economic Impact | Fisheries | |
| Reduced condition factor was also reported in infected Pacific Oysters (Crassostrea gigas) in Humboldt, Yaquina, and Willapa Bays. However, no relation was seen between infection and mortality (Chew et al. 1965; Katkansky et al. 1967). Reduced condition factor (smaller body mass, higher water content, less fat) reduces the quality of oysters. | ||
