Aquaculture ponds and their impact on local and regional C, N and P budgets

Worldwide aquaculture production is increasing at annual rates of 5–11% to meet the global increase in animal protein demand. While aquaculture can be an important mean for poverty alleviation and food security in poor regions, the aquaculture boom also comes with environmental costs. In an ongoing project we are focusing on fish ponds. This type of aquaculture systems is globally one of the most commonly used. One of these effects of (excessive) nutrient addition to ponds is eutrophication of down-stream waters. The amount of C, N and P added to fish ponds varies widely, as is the percentage of these elements that finally ends up in the fish. We expect this variation to be attributable to the type of fish, type of feed and fish pond management. Field work in Brazilian fish ponds is currently on hold but literature-based research can already be conducted. If you are interested in developing your research within this theme, please contact us.
