Book chapter- In SA Levin (Ed.), Encyclopedia of Biodiversity, 2013 - Academic PressBiophysical impacts of aquaculture, with consequences for biodiversity, vary with species and culture systems and include issues such as: nutrient enrichment/removal, chemicals, land use, species introductions, genetic flow to wild populations, disturbance of balance or introduction of pathogen/parasites, consumption of capture fishery resources, energy, and greenhouse gas emissions. Guiding principles, labeling schemes and various tools are needed to analyze performance and conformance. Ecological footprints and life-cycle analysis aim to capture biophysical performance, including up- and downstream effects of policy decisions. Aquaculture provides a range of services but also makes demands and impacts on ecosystem functions, services, and thus biodiversity.
