Environment-friendly compound feeds capable of improving fertility of sciaenops ocellatus parent fish

Abstract

The invention relates to environment-friendly compound feeds capable of improving the fertility of sciaenops ocellatus parent fish. The compound feeds are characterized in that the compound feeds consist of a basic feed component and a Chinese herbal medicinal additive, wherein the weight part ratio of the basic feed component to the Chinese herbal medicinal additive is (99.5-99.9):(0.1-0.5); the basic feed component consists of the following raw materials in parts by weight: 20 to 40 parts of fish meal, 10 to 30 parts of soybean meal, 5 to 15 parts of peanut meal, 4 to 10 parts of chicken meal, 10 to 30 parts of strong flour, 5 to 15 parts of beer yeast, 3 to 10 parts of squid paste, 1 to 5 parts of phospholipid oil, 1 to 5 parts of fish oil, 0.2 to 0.5 part of decavitamin, 0.5 to 1.5 parts of complex mineral, 0.3 to 1.0 part of a feed attractant, 0.1 to 0.3 part of L-ascorbate-2-phosphate, 1 to 3 parts of calcium dihydrogenphosphate, 0.01 to 0.05 part of a mildew-proof agent, 0.2 to 0.8 part of Te Mianwang, 0.1 to 0.3 part of salt, 0.05 to 0.15 part of choline chloride and 0.01 to 0.03 part of vitamin E. The feeds are nutritional and environment-friendly, the sexual maturity time of the sciaenops ocellatus parent fish can be shortened, the gonad development of the sciaenops ocellatus parent fish can be promoted, and the fertility of the sciaenops ocellatus parent fish can be improved.
