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]
Capture includes fish, crustaceans, molluscs, etc. [1] [2] [3] World capture fisheries and aquaculture production, from FAO's Statistical Yearbook 2021 [ 4 ] ↑ By species group
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 aquaculture or farming of piscivorous fish, like salmon, does not help the problem because they need to eat products from other fish, such as fish meal and fish oil. Studies have shown that salmon farming has major negative impacts on wild salmon, as well as the forage fish that need to be caught to feed them.
The wild Atlantic salmon fishery is commercially dead; after extensive habitat damage and overfishing, wild fish make up only 0.5% of the Atlantic salmon available in world fish markets. The rest are farmed, predominantly from aquaculture in Norway, Chile, Canada, the UK, Ireland, Faroe Islands, Russia and Tasmania in Australia.
The larger fish processing companies have their own fishing fleets and independent fisheries. The products of the industry are usually sold wholesale to grocery chains or to intermediaries. Fish processing can be subdivided into two categories: fish handling (the initial processing of raw fish) and fish products manufacturing.
Raising fish in cages in a lake in a relatively undeveloped environment. Urban aquaculture employs water-based systems, the most common, which mostly use cages and pens; land-based systems, which make use of ponds, tanks and raceways; recirculating systems are usually high control enclosed systems, [clarification needed] whereas irrigation is used for livestock 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.
