Background information and definitions
Aquaculture systems can negatively impact subtidal benthic invertebrate communities through pollution and diminished water quality (Wu et al. 1994). By locating aquaculture systems in areas that already have poor water quality (for instance due to sewage outfall), the source of pollution is restricted to that already impacted zone. This may potentially relieve other areas from additional pollution, without significantly further degrading the already impacted area which likely already holds an impacted subtidal benthic invertebrate community.
Evidence for other interventions related to the relocation of aquaculture activities are summarised under “Threat: Pollution – Locate aquaculture systems in locations with fast currents”, “Locate aquaculture systems in vegetated areas”, and “Locate artificial reefs near aquaculture systems (and vice versa) to act as biofilters”.
