Protein, unsaturated fatty acids and essential amino acids in the muscle of high whitebait are much higher than those of most common cultured fish, while the average protein content in the muscle is 18.83%, only lower than that of snakehead, and the average fat content is 13.75%. Unsaturated fatty acids are higher than saturated fatty acids, and highly unsaturated fatty acids are higher, with an average amino acid content of 65448. The eggs of whitebait are rich in protein and high in vitamin E, which can prevent the unsaturated fatty acids contained in them from being destroyed by oxidation.
