Marine aquaculture is a fast developing sector, with a focus on mussels, oysters, abalone, seaweeds, and prawns. Of these, mussel farming is the best established. Abalone culture is now well established, centred in the Hermanus area on the Cape south coast. There is also an experimental offshore farm (cage culture) off Gansbaai for salmon." [1]
"Fish cages should be moved further from the coast, and more research and development of offshore cage technology must be promoted to this end. Experience from outside the aquaculture sector, e.g. with oil platforms, may well feed into the aquaculture equipment sector, allowing for savings in the development costs of technologies."
However, species originally from Africa have been widely introduced and have become economically important as food fish in many countries. China, the Philippines, Taiwan , Indonesia, and Thailand are the leading suppliers, and these countries altogether produced about 1.1 million metric tons (1.1 × 10 ^ 6 long tons) of fish in 2001 ...
However, 2005 research on rockfish shows that large, elderly females are far more important than younger fish in maintaining productive fisheries [citation needed]. The larvae produced by these older maternal fish grow faster, survive starvation better, and are much more likely to survive than the offspring of younger fish.
The fisheries sector accounts for 3% of Morocco's GDP. The government estimates the number of direct and indirect jobs at 400,000 (including 104,000 fishermen). [4] The small-scale fisheries sector (100,000 people) lags far behind other branches of the fishing industry owing to the lack of infrastructure and of harbour facilities and plant.
The fishing industry includes any industry or activity that takes, cultures, processes, preserves, stores, transports, markets or sells fish or fish products. It is defined by the Food and Agriculture Organization as including recreational, subsistence and commercial fishing, as well as the related harvesting, processing, and marketing sectors. [1]
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) is an international organisation which conducts agricultural research for rural development, headquartered in Patancheru, Hyderabad, Telangana, India, with several regional centres (Bamako (Mali), Nairobi (Kenya)) and research stations (Niamey (Niger), Kano (Nigeria), Lilongwe (Malawi), Addis Ababa (Ethiopia ...
