Background information and definitions
The expanding aquaculture industry has led to the accidental introduction of diseases, and non-native and other problematic species into the wild marine environment (Bax et al. 2003; Fitridge et al. 2012; Hewitt et al. 2004; Manchester & Bullock 2000). There, they can impact on native subtidal benthic invertebrate species through predation, competition for resources (food & space), contamination (for pathogens and diseases), or hybridization (through reproduction) (Bishop et al. 2010). This could be potentially avoided through the implementation of regular inspections of the facilities (Fitridge et al. 2012; Reise et al. 1998).
Evidence for related interventions are summarised under “Threat: Invasive and other problematic species, genes and diseases – Implement quarantine to avoid accidental introduction of disease, non-native or problem species”.
