Answer 1

Answer:

Aquaculture (less commonly spelled aquiculture[2]), also known as aquafarming, is the farming of fish, crustaceans, mollusks, aquatic plants, algae, and other organisms. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish.[3] Mariculture commonly known as marine farming refers to aquaculture practiced in marine environments and in underwater habitats.

Aquaculture production by region

According to the Food and Agriculture Organization (FAO), aquaculture "is understood to mean the farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants. Farming implies some form of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc. Farming also implies individual or corporate ownership of the stock being cultivated."[4] The reported output from global aquaculture operations in 2014 supplied over one half of the fish and shellfish that is directly consumed by humans;[5][6] however, there are issues about the reliability of the reported figures.[7] Further, in current aquaculture practice, products from several pounds of wild fish are used to produce one pound of a piscivorous fish like salmon.[8]

Particular kinds of aquaculture include fish farming, shrimp farming, oyster farming, mariculture, algaculture (such as seaweed farming), and the cultivation of ornamental fish. Particular methods include aquaponics and integrated multi-trophic aquaculture, both of which integrate fish farming and aquatic plant farming. The Food and Agriculture Organization describes aquaculture as one of the industries most directly affected by climate change and its impacts.[9] Some forms of aquaculture, such as seaweed farming, have the opportunity to be part of climate change mitigation, while other forms of aquaculture have negative impacts on the environment, such as through nutrient pollution or disease transfer to wild populations.

An increase in demand for food sources and globalization has led to an increase in fishing. Aquaculture currently estimated to account for approximately 13 percent (10.2 million tons) of world fish production.
