Regional Impacts
Economic Impact | Shipping/Boating | |
Hydroides elegans has been found in fouling of boats and marinas in the Gulf of Mexico and southern Florida (Hartman 1952; Renaud 1956; Ruiz et al., unpublished data) and probably has some impact in boat and ship fouling in those regions. | ||
Ecological Impact | Competition | |
Tubeworms (Hydroides spp., probably including H. elegans) were dominant fouling organisms on the shells of living and dead oysters in the Mosquito Lagoon, Florida (Walters 2001; Boudreaux et al. 2006), and are likely to compete with adult oysters for food and oyster spat for space. | ||
