The UN Sustainable Development Goal 14 ("life below water"), Target 14.7 includes aquaculture: "By 2030, increase the economic benefits to small island developing states and least developed countries from the sustainable use of marine resources, including through sustainable management of fisheries, aquaculture and tourism".
Aquaculture is practiced all over the world and is extremely popular in countries such as China, where population is high and fish is a staple part of their everyday diet.

Hatchery production confers three main benefits to the industry: 1. Out of season production Consistent supply of fish from aquaculture facilities is an important market requirement. [7]
The rice provides the fish with shelter and shade and a reduced water temperature, along with herbivorous insects and other small animals that feed on the rice. [7] Rice benefits from nitrogenous waste from the fish, while the fish reduce insect pests such as brown planthoppers, diseases such as sheath blight of rice, and weeds. [7]
Aquaculture production by region (2020), Our World in Data. Prior to the 1980s, global fish supply from aquaculture did not represent a significant food source. [4] However, depletion of ocean fisheries and subsequent decline of capture fishery production caused aquaculture to grow rapidly.
