The invention provides a feed additive for improving the reproductive capacity of wave-resistant fish, which comprises the following raw materials in parts by weight: 16-24 parts of ferrous fumarate, 12-18 parts of coix seeds, 6-12 parts of black rice, 5-10 parts of pueraria flowers, 4-8 parts of astragalus membranaceus, 1-2 parts of turtle shells, 0.8-1.6 parts of unsaturated fatty acids and 15-20 parts of carriers; the earthworm extract and the ferrous fumarate need to be magnetized in advance, and the mass ratio of the earthworm extract to the ferrous fumarate is 60-70: 1. The feed additive can improve reproductive capacity of anti-sea fish, and improve egg laying amount, ovum fertilization rate, hatchability and fry survival rate. |
