The use of fish oils by aquaculture is the key impediment on the future growth and sustainability of the industry. Fish oil, the key provider of health-beneficial omega-3 long-chain polyunsaturated fatty acids, fluctuates drastically in supply and cost, and is extracted unsustainably from world oceans. Resultantly, its persistent use has fueled a heated global debate and sparked a generation of research focus into possible means of reducing the aquaculture industry's dependence on this resource. This chapter introduces the subject of fish oil usage in aquaculture on a global basis, and briefly traces the history of related issues. Accordingly, the major fish species utilized for fish meal and fish oil production are traced and the chemical and nutritional characteristics of fish oils of different origins are provided. The future expected availability of fish oil for aquaculture and the sustainability of the reduction industry are subsequently discussed.
