    Abstract

    Production of seafood has quadrupled over the last 50 years. With the seafood consumption nearly doubling in the last 50 years there has been increased pressure on fish stocks across the world. Globally, the share of fish stocks which are overexploited are also increasing and sustainability of resources is being attempted at a faster rate since current levels of wild fish catch are unsustainable. Globally, the percentage of fish stocks that are within biologically sustainable levels have decreased from 90 percent in 1974 to 65.8 percent in 2017 (SOFIA, 2020). The volume of global fish production amounted to 177.8 million metric tons in 2019, which rose up by 29.7 t from 148.1 million metric tons in 2010. In the Western Indian Ocean, total landings continued to increase and reached 5.3 million tonnes in 2017. The 2017 assessment estimated that 66.7 percent of the assessed stocks in the Western Indian Ocean were fished within biologically sustainable levels, while 33.3 percent were at biologically unsustainable levels. The Eastern Indian Ocean continues to show a steady increase in catches, reaching an all-time high of 7 million tonnes in 2017. Since 1961, average per capita fish consumption has been increasing in Asia at an annual rate of 2 percent.
