Aquaculture and Fisheries Stock , fishing Maps 2011
The oceans' marine life forms are declining from human overfishing, pollution, habitat destruction and global warming.Exclusive Economic Zones (EEZs)
Each coastal country has an EEZ extending 200 miles offshore. Legal mechanisms and investment incentives are being implemented to privatize and develop these marine areas for open ocean aquaculture and other industrial uses. This commercial exploitation will be beyond sub-national (state or provincial) regulation. Used offshore oil platforms are likely to be recycled as anchor points for large scale open net aquaculture. |
Aquaculture - Industrial farming in fresh or salt water of fish, mollusks, crustaceans and plants
Aquaculture is rapidly increasing its annual global harvest and seems to offer hope for increased food production. However, for some of the more than 210 farmed aquatic animal and plant species,8 particularly salmon and shrimp, the methods currently used require high energy inputs and can cause environmental degradation similar to industrial/chemical agriculture or factory farming of livestock. These are |
SOURCE: UN FAO FISHSTAT Database, http://www.fao.org/fi/statist/FISOFT/FISHPLUS.asp | The high protein feed for farmed salmon is largely composed of ocean caught fish meal and meat offal from poultry and hog processing. Because of bio-accumulation of toxins in their feed, "Consumption of farmed salmon even at relatively low frequencies results in elevated exposure to dioxins and dioxin-like compounds with commensurate elevation in estimates of health risk." 6 Farming of shrimp in asia has lead to significant destruction of natural mangrove ecosystems. Genetically engineered fish are being readied for commercial production in open net pens. |
"75% of the major marine fish stocks are either depleted, overexploited or being fished at their biological limit." 1 |
"In the commercial fishing areas between North America and the British Isles, there has been a 90% decline in predatory fish populations, notably cod." 3 |
Fish are a major source of food protein for billions of people and their domesticated animals. |
