A significant part of Indian food production involves fisheries and aquaculture, which contribute to agricultural exports and employ around fourteen million people. Since independence, the nation has consistently increased fish production as a result of its vast aquatic resources. A total of 6.3 percent of world fish production comes from the industry, which contributes 1.1 percent to GDP and 5.15 percent to agricultural GDP. A total of 10.07 million metric tons of fish are produced in the inland sector, and around 65 percent are produced in the cultural sector. Increasing fish diseases have slowed aquaculture production and product trade in India, threatening fishermen's livelihoods. Infections can be caused by a number of factors, including low physicochemical and microbiological quality of culture water, high stocking density, and poor nutrition. It is possible for seed fish and adults to become deformed and die from exposure to pollution and suspended particles. As a result of different opportunistic bacterial infections and parasites, the fish industry suffers a significant loss in mortality and morbidity, decreased growth, and increased chemical control and prevention costs.
