| 520 | |a"Environmental impacts of aquaculture vary from minimal to severe impairment depending upon the site characteristics, the type, size and practices of the operation, and the nature of the wastes in the aquaculture effluent. The most common impact of aquaculture is nutrient enrichment potentially resulting in eutrophication. Other potential changes include deterioration of water quality, changes in physical and chemical characteristics of the sediment, shifts in algal and invertebrate communities, increase of birds around net cages, and increased interactions, disease transmission, and competition between farmed and wild fish. A review of the existing environmental monitoring programs indicates a lack of consistency across Canada"--Abstract. |
