Vectors

| Probable | Hull Fouling |
Regional Impacts
| Ecological Impact | Competition | |
| Skolka and Preda (2010) suggest that the success and abundance of A. improvisus has prevented the settlement of other barnacle species, including introduced A. eburneus, A. amphitrite, and native Balanus crenatus (Skolka and Preda 2010). | ||
| Ecological Impact | Food/Prey | |
| 'Larval stages represent a valuable food resource' (Skolka and Preda 2010). | ||
| Economic Impact | Shipping/Boating | |
| 'Fouling organisms, like barnacles (A. improvisus or the polychaete Ficopomatus enigmaticus), are harmful because their biomass increases the fuel consumption of ships. Such organisms also increase the corrosion rate of metallic submerged structures' (Skolka and Preda 2010). | ||
