Background information and definitions
Aquaculture systems can negatively impact subtidal benthic invertebrate communities through pollution and diminished water quality (Wu et al. 1994). To limit the amount of pollution emitted by one aquaculture site, stocking density could be reduced (Naylor et al. 2000). A lower number of organisms in one area will produce less waste and limit organic enrichment. This may potentially reduce the level of impact in the vicinity of the aquaculture site and allow some recovery of the subtidal benthic invertebrate community.
