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.
World capture fisheries and aquaculture production by species group, from FAO's Statistical Yearbook 2021 [1]. The global commercial production for human use of fish and other aquatic organisms occurs in two ways: they are either captured wild by commercial fishing or they are cultivated and harvested using aquacultural and farming techniques.
Global capture fisheries and aquaculture production reported by FAO, 1990–2030 World aquaculture production of food fish and aquatic plants, 1990–2016 Harvest stagnation in wild fisheries and overexploitation of popular marine species, combined with a growing demand for high-quality protein, encouraged aquaculturists to domesticate other ...
World fish production, consumption and trade are expected to increase, but with a growth rate that will slow over time. Despite reduced capture fisheries production in China, world capture fisheries production is projected to increase slightly through increased production in other areas if resources are properly managed.
According to a 2019 FAO report, global production of fish, crustaceans, molluscs and other aquatic animals has continued to grow and reached 172.6 million tonnes in 2017, with an increase of 4.1 percent compared with 2016. [25] There is a growing gap between the supply of fish and demand, due in part to world population growth. [26]
Since 2000, aquaculture has been the fastest growing food production sector, growing 5.8% per year, [6] supplying over 100 metric tonnes of fish, shellfish and seaweeds from 425 species in 2017. [3] [4] Global aquaculture production by country in million tonnes, 1950–2010, as reported by the FAO. Based on data sourced from the FishStat database.
Following is a sortable table of the world fisheries' harvest in 2022. The tonnage from capture and aquaculture is listed by country. Capture includes fish , crustaceans , molluscs , etc. [ 1 ] [ 2 ] [ 3 ]
Ray Hilborn, According to Hilborn, the "loss of some species, and indeed transformation of the ecosystem is not incompatible with sustainable harvests." For example, in recent years, barndoor skates have been caught as bycatch in the western Atlantic. Their numbers have severely declined and they will probably go extinct if these catch rates continue. Even if the barndoor skate goes extinct ...
