Global aquaculture provides more fish for human consumption than wild capture fisheries, with projected provisioning of 60% by 2030 . Aquaculture can contribute to SDGs by reducing poverty and food insecurity, filling increasing aquatic food demand shortages from declining capture fisheries production   and improving social inequities for poor rural communities . Global aquaculture production reached 82 million tonnes  of food fish, crustaceans, molluscs and other aquatic animals from inland  and marine  systems, and 32 Mt of aquatic plants in 2018 . China, India, Indonesia, Vietnam, Bangladesh, Egypt, Norway and Chile are major production regions . The range of species, farming methods and environments makes aquaculture the most diverse, long-standing farming practice in the world, with an estimated global sectoral value of USD 250 billion in 2018 , but it is dominated by 20 finfish, 9 mollusc and 6 crustacean species . Inland aquaculture in freshwater and coastal ponds accounts for 85-90% of farmed production . Globally, 20.5 million people are engaged in aquaculture , where marine finfish farming is primarily conducted by high-income countries and inland production is dominated by small-scale producers in lower-middle-income countries .
