Regional Impacts
| Ecological Impact | Habitat Change | |
| Codium fragile attached to the shells of Bay Scallops (Argopecten irradians) in the Niantic River, Connecticut, interfered with the movement of the scallops, and increased their mortality (Ramus 1971). | ||
| Economic Impact | Fisheries | |
| Codium fragile is believed to have contributed to the mortality of Bay Scallops in Long Island Sound. However, the role of C. fragile is difficult to determine, since the seaweed also attaches to dead shells (Ramus 1971). | ||
