Aquaculture is the farming of aquatic organisms such as fish, crustaceans, mollusks and aquatic plants. It is a rapidly growing industry that plays a significant role in providing food security, improving nutrition and promoting sustainability. Food security is a major global concern, with millions of people around the world suffering from malnutrition and hunger. Food security, nutrition and sustainability are global challenges that need urgent attention to achieve a better and more sustainable future. Aquaculture technologies can help to address this problem by increasing the availability and accessibility of fish and other aquatic foods, providing a source of protein-rich food, improving nutrition, enhancing sustainability, generating income and improving food safety. In addition, aquaculture technologies play an important role in promoting nutrition. Fish and other aquatic foods are a good source of essential nutrients that are important for human health, including omega-3 fatty acids, vitamin D and minerals like iron and zinc. By increasing access to these foods, aquaculture can help to improve nutrition and reduce the incidence of diet-related diseases. Fish and shellfish are rich in omega-3 fatty acids, which have been linked to improved heart health, brain function and other health benefits. By incorporating fish and shellfish into their diets, people can improve their overall nutritional intake and reduce the risk of chronic diseases.
