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 farming was officially proposed by the colonial authorities and the Kajjansi Fish Experimental Station established in 1947. However, the introduction of carp was embroiled in controversies due to differences among the lead scientists on the possible adverse impact of common carp on the indigenous aquatic environment in case they escaped ...
The site attracts a number of bird species both Waterfowl species and land birds seen around the fish ponds and at the edges of the site. [1] The centre undertakes research on 300 fish species that are extinct as well as the threatened ones like the riverine Ningu ( Labeo victorianus ), Kisinja ( Barbus spp ), Nkolongo ( Synodontis spp ) and ...
"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."
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.
Subsets of it include (offshore mariculture), fish farms built on littoral waters (inshore mariculture), or in artificial tanks, ponds or raceways which are filled with seawater (onshore mariculture). An example of the latter is the farming of plankton and seaweed, shellfish like shrimp or oysters, and marine finfish, in saltwater ponds
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 ...
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.
