Background information and definitions
Aquaculture systems can negatively impact invertebrate subtidal communities through pollution and diminished water quality (Wu et al. 1994). Aquaculture systems can be located in areas with submerged vegetation, such as seagrass or kelp, which can help absorb the waste product effluents and mitigate the pollution originating from the installations (Mirto et al. 2010). This may help locally reduce or mitigate the deterioration in water quality in the area and benefit subtidal benthic invertebrates.
Evidence for other interventions related to the relocation of aquaculture activities are summarised under “Threat: Pollution – Locate aquaculture systems in already impacted areas”, “Locate aquaculture systems in locations with fast currents”, and “Locate artificial reefs near aquaculture systems (and vice versa) to act as biofilters”.
