2. Laboratory of Aquaculture & Artemia Reference Center, Ghent University, Belgium Overview of presentation Importance of fish & shellfish in human nutrition Fisheries (= hunting) aquaculture (= farming) History: from “food” aquaculture to “business” aquaculture Critical bottleneck in aquaculture: seed availability Need for domestication including difficult larviculture Farming systems: cages, ponds, tanks; extensive, intensive Production statistics Challenges for future aquaculture Case study Uganda: opportunities and challenges

3. Fish in the Human Food Chain  Protein  n-3 HUFA  Fe, I 2, Ca  vitamin A Fish Food Security = availability + access

42. FAO, 2009

43. Laboratory of Aquaculture & Artemia Reference Center, Ghent University, Belgium “Aquaculture is probably the fastest growing food-producing sector, and currently accounts for almost 50% of the world’s food fish and is perceived as having the greatest potential to meet the growing demand for aquatic food.” “Given the projected population growth over the next two decades, it is estimated that by 2030 at least an additional 40 million tons/year of aquatic food will be required to maintain the current per caput consumption.”

44. Laboratory of Aquaculture & Artemia Reference Center, Ghent University, Belgium INCREASED MARKET DEMAND stagnant capture fisheries INCREASED aquaculture production environmental problems? human health risks? sustainable? more responsible farming !

45. Priorities for future aquaculture: from empiricial farming towards a knowledge-based bio-industry Aquaculture: the blue biotechnology of the future ?
