Biosecurity is key to productive aquaculture systems. Biosecurity encompasses all measures designed to prevent diseases from occurring and from spreading by isolating, as much as possible, animal farm populations from external contamination. Recurring or prolonged contact with external environments (water, sediment, wildlife) favors the development of new diseases.
The other type of biomonitoring is to ensure compliance with regulations or guidelines or to ensure water quality is maintained. Biomonitoring involves the use of indicators, indicator species or indicator communities. Generally benthic macroinvertebrates, fish, and/or algae are used. Certain aquatic plants have also been used as indicator species for pollutants including nutrient enrichment (Phillips and Rainbow, 1993; Batiuk et al., 1992).
