Regional Impacts
| Ecological Impact | Habitat Change | |
| Codium fragile attached to Eastern Oysters (Crassostrea virignica) caused oysters to be floated away from their beds, when the algae became saturated with oxygen, and lifted the oysters off the bottom (Ramus 1971). | ||
| Economic Impact | Fisheries | |
| Mortality caused by Codium fragile is believed to have raised the priced of local oysters on Cape Cod. Codium fragile also interfered with oyster-harvesting equipment (Galtsoff 1965; Ramus 1971). | ||
