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). Biological controls can be used to try to reduce the population of non-native, invasive or other problematic species (Fitridge et al. 2012; Thresher & Kuris 2004). Forms of biological controls include the release of native or non-native predators, parasites, or diseases likely to affect specific non-native, invasive or other problematic species. It should be kept in mind that using native species as biological controls is always a preferred safer option than using non-native ones (Thresher & Kuris 2004).
