Regional Impacts

Ecological ImpactParasitism
Reduced condition factor was also reported in infected Pacific Oysters (Crassostrea gigas) in the Hood Canal and Oyster Bay, Puget Sound. However, no relation was seen between infection and mortality (Chew et al. 1965; Katkansky et al. 1967).
 
Economic ImpactFisheries
Reduced condition factor was also reported in infected Pacific Oysters (Crassostrea gigas) in the Hood Canal and Oyster Bay, Puget Sound. 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.
