Conservation of Aquaculture Wastewater and Nutrients through Vegetable Crop Production

摘要

Global aquaculture production has expanded at an average annual rate of 6.2% during 2000-2012, with world aquaculture production of 66.7 million tons in 2012, outpacing world population growth rate of 1.6%. According to Food and Agriculture Organization (FAO), aquaculture is estimated to supply 62% of the world's fish for human consumption by 2030. However, aquaculture produces huge volumes of wastewater containing nitrogen (N) and phosphorus (P), considered to be environmental pollutants, leading toeutrophication of water bodies. Therefore, effective management of aquaculture effluents is critical to protect natural water bodies while conserving water resources for agricultural production.
