 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.There is a growing gap between the supply of fish and demand, due in part to world population growth.The journal "Science" published a four-year study in November 2006, which predicted that, at prevailing trends, the world would run out of wild-caught seafood in 2048.
