When the protein intake of fish is insufficient, the growth is slow, the immunity of the body is reduced, and the protein with the appropriate ratio of various amino acids is required.
2. Fats, especially essential fatty acids, are important regulators of the immune response of fish and shrimp. The addition of essential fatty acids to the diet can improve the humoral and cellular immunity of animals, promote the production of cellular immune factors, have an important impact on the proliferation of lymphocytes stimulated by mitosis, and enhance the phagocytic ability of macrophages.
