World capture fisheries and aquaculture production by species group [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.
The tonnage from capture and aquaculture is listed by country. Capture includes fish , crustaceans , molluscs , etc. [ 1 ] [ 2 ] [ 3 ] World capture fisheries and aquaculture production, from FAO's Statistical Yearbook 2021 [ 4 ]
The United States imports aquaculture products from these and other countries, and operates an annual seafood trade deficit of over $9 billion. [ 20 ] Shellfish ( oysters , clams , mussels ), account for two-thirds of marine aquaculture production, followed by salmon (25 percent) and shrimp (10 percent).
Overproduction of shrimp increased vulnerability of the shrimp aquaculture population to viruses, and in the Great Shrimp Disaster of 1993, the white spot virus wiped out almost all of China's black tiger shrimp aquaculture industry. [14]: 172 By the early 2000s, shrimp aquaculture recovered thanks to a species switch to Pacific white shrimp.
World capture fisheries and aquaculture production by species group [1] This is a list of aquatic animals that are harvested commercially in the greatest amounts, listed in order of tonnage per year (2012) by the Food and Agriculture Organization. Species listed here have an annual tonnage in excess of 160,000 tonnes.
Aquaculture involves cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural conditions and can be contrasted with commercial fishing, which is the harvesting of wild fish. [2] Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems.

Fish chosen for extensive aquaculture are very hardy and often do well in high densities. Seaweed, prawns, mussels, carp, tilapia, tuna and salmon are the most prominent forms of extensive aqua cultured seafood. Extensive aquaculture facilities have negative impacts on the environment as well.
