Community opportunities in aquaculture: what are the possibilities and limits?
MetadataShow full item record
Aquaculture now contributes 47% of fish available for human consumption – up from 9% in 1980. This shift to aquaculture offsets the stagnation in the production from capture fisheries (FAO 2012). By 2030, demand for fish is expected to reach 261 million tonnes, but fish production is only expected to rise to 210 million tonnes; demand will therefore exceed supply by 50 million tonnes. Africa is likely to produce 11 million tonnes by 2030, but the demand will be as high as 18 million tonnes (FAO 2013).
