Background information and definitions
Non-native, invasive and other problematic species can impact on native subtidal benthic invertebrate species through predation, competition for resources (food & space), contamination (for pathogens and diseases), or hybridization (through reproduction) (Molnar et al. 2008; Bishop et al. 2010). Non-native species can become attached to the hard surfaces of vessels and anthropogenic structures, such as ship hull, anchors and chains, oil rigs, wind farms, pontoons, or buoys, which then act as “stepping stones” for their introduction into new environments (Adams et al. 2014; Bulleri & Airoldi 2005; Mineur et al. 2012). Using antifouling coating can potentially prevent the attachment of non-native (and native) species, hence reduce the risk of introduction to new location and the risk non-native species pose to native subtidal benthic invertebrates.
Evidence for other interventions related to antifouling coatings are summarised under “Threat: Invasive and other problematic species, genes and diseases – Use non-toxic antifouling coatings on surfaces” and “Restrict the use of tributyltin or other toxic antifouling coatings”.
