About 43 percent of fish for human consumption is produced in fish farms, according to a report of the UN Food and Agriculture Organization (FAO). Emma Marris adds in Nature online (6.9.2006) that besides taking some pressure off over-fished wild populations, also environmental concerns raise. But according to the FAO a further rise in aquaculture is needed to meet the future demand in protein-rich food. Some 40 million tons more are necessary for the global population in 2030.
Today, 45.5m tons are produced in aquaculture, and 60m tons by wild catches. In an opinion piece for the NY Times (8.9.2006) Paul Greenberg gives some hints on seafood for consumers: "Considering what's at stake is the survival of the ecosystem of the world's oceans, I'd rather eat fewer, smaller and more expensive fish than no fish at all."
