Regional Impacts
| Economic Impact | Fisheries | |
| Styela clava was found fouling aquaculture gear at 21 sites, and cultured Bay Scallops (Aequipecten irradians) at two sites, of 26 aquaculture sites surveyed on Marthas Vineyard (Carman et al. 2010). This tunicate was also reported at aquaculture sites in Rhode Island (Carman et al. 2010). | ||
| Ecological Impact | Competition | |
| Styela clava is abundant in harbors with poor and fair as well as good water quality (Carman et al. 2007) | ||
