Capture-based aquaculture is a global activity but has specific characteristics that depend on geographical location and the species being cultured. The species groups used in capture-based aquaculture include molluscs (e.g. oysters, mussels, scallops), crustaceans (e.g. shrimps, crabs) and finfish (e.g. eels, grey mullets, milkfish, yellowtails, groupers, rabbitfish, tunas). The scale of such practices is difficult to quantify, but it is estimated that about 20 per cent of aquaculture production comes from capture-based aquaculture. The total value of the farmed production of the four species groups considered in this report (the figures reported to FAO are believed to be underestimates) in 2000 alone exceeded US$ 1.7 billion. This report focuses on four species that show high market demand and value and have a short grow-out time to market size – eels, yellowtails, groupers and tunas. A description of the rearing, harvesting and marketing practices for each species is provided, together with a review of environmental, social, economic, food safety and management issues.
