Fish constitutes approximately 17 percent of the animal protein consumed by the global population. The fish production from capture fisheries (90.3 mt) has been nearly stagnant for many decades, whereas the demand for fish has increased significantly due to an increased awareness of its health benefits. Aquaculture is the fastest-growing food production sector in the world, with an estimated production of 122.6 million tonnes. Aquaculture is the only means of meeting the additional demand for fish consumption. The Asia-Pacific region has been continuing to be the major producer of fish. In 2018, aquaculturists were reported to farm about 622 species or species items including 387 finfishes, 111 molluscs, 64 crustaceans, seven frogs and reptiles, ten aquatic invertebrates and 43 aquatic plants. FAO highlights the following key strategic points for achieving the blue transformation; increase the development and adoption of sustainable aquaculture systems; ensure that aquaculture is integrated into national, regional and global development strategies and food policies; ensure that aquaculture production meets the growing demand for aquatic food and enhances inclusive livelihoods, and improve capacities at all levels to develop and adopt innovative technology and management practices for more efficient and resilient aquaculture industry. The technological landscape in the global aquaculture scenario is changing rapidly. Genomic selection, recirculating aquaculture systems, aquaponics, and novel aquafeed ingredients, rapid disease diagnostics, oral vaccines are some of the newer technological innovations that steer the aquaculture sector. From 2000-2018, aquaculture production in freshwater, brackish water and marine water increased at a compound annual growth rate of 5.7 percent, 7.7 percent and 5.2 percent respectively while total aquaculture production grew at an annual growth rate of 5.6 percent. Global food supply and per capita consumption of fish and fish products continued to increase faster than human population
