Ocean ecosystem conservation and seafood security

Marine food should be a renewable resource for humans. However, world fish catches have peaked since the 1990s, despite increases in aquaculture production. Fish provide more than 2.9 billion people with at least 15 per cent of their animal protein intake (FAO Fisheries and Aquaculture Department, 2009). Tuna (Thunnus spp.) stocks have decreased severely from overfishing since the 1980s (Myers and Worm, 2003). Bluefin tuna (T. thynnus) is already listed as a “critical species” by the IUCN (International Union for Conservation of Nature). Although aquaculture production is increasing worldwide, many aquaculture programmes such as shrimp farming have caused the destruction of mangrove forests over the past 20 years in East Asia (Primavera, 2005), and marine pollution has also been reported for farmed Atlantic salmon (Hites et al., 2004).
