The fatty acid composition of aquaculture fish is of great importance in enhancing their nutritional value and human health. With the development of the aquaculture industry, researchers are increasingly focusing on how to optimize the fatty acid composition of fish through genetic and biochemical strategies. This study aims to explore the correlation between the fatty acid composition of aquaculture fish and human health. The study found that the fatty acid profiles of different fish are influenced by their diets, with marine fish generally having higher levels of n-3 polyunsaturated fatty acids such as EPA and DHA, compared to freshwater fish. The type of feed used significantly affects the nutritional value of the fish, with sustainable feeds often resulting in lower levels of EPA and DHA. Selective breeding has shown potential to increase the levels of beneficial fatty acids in fish muscle, and alternative lipid sources such as microalgae and genetically modified crops may serve as future sources of essential fatty acids. The study indicates that both genetic and biochemical strategies can effectively enhance the fatty acid composition of aquaculture fish, thereby improving their nutritional value, which is significant for the prevention of cardiovascular diseases. This research aims to provide theoretical basis and practical guidance for future studies and practical applications.
