Reeves shad parent fish nutrition reinforcement forage and its preparation method

Abstract

The invention provides a Reeves shad parent fish nutrition reinforcement forage. The Reeves shad parent fish nutrition reinforcement forage is composed of the following raw materials, by weight, 30 parts of an artificial compound forage, 35 parts of fresh trash fish, 20 parts of clam, 15 parts of nereid, 0.5 parts of vitamin C, 0.5 parts of vitamin E, 0.5 parts of fish oil, and 0.1 part of soybean lecithin. The Reeves shad parent fish nutrition reinforcement forage has the following technical effects: 1, a bait palatability problem is solved, and parent fish can effective take various reinforcement nutrients; and 2, the addition of a proper amount of the fish oil can effectively provide various fatty acids required by the breeding of the parent fish and does not cause over-nutrition, VC and VE can effectively prevent the oxidation of the fatty acids in the parent fish, remove excess free radicals generated in the body and enhance the fish immunity, VE can also promote the sexual hormone secretion and improve the fecundity of the parent fish, and lecithin is helpful for adjusting the nutrient digestion and absorption of the parent fish, is an energy source in the embryonic development phase and can also participate in the synthesis of fish body fats of larva fish.

Description

Technical field [0001] The present invention involves a kind of reinforced feed and preparation methods of catfish parentfish, which belongs to the field of animal food technology. Background technique [0002] Catfish is a rare and precious economy in China. It is produced in the lower reaches of the Yangtze River. It is known as a treasure in the south of the river.In 1988, it was included in the first -level protection species in the National Key Protection of China.In recent years, due to excessive fishing, water environmental pollution, and water conservancy construction, the natural resources of catfish have decreased sharply.At present, the market is mostly introduced from the United States, which is sold as catfish.With the continuous increase of catfish breeding, natural seedlings are far from meeting the needs of the breeding industry.In the process of artificial reproduction and development of catfish, the nutrition of parentfish directly affects the quality of fertili...

Problems solved by technology

However, only feeding on fresh miscellaneous fish can easily cause nutritional imbalance of broodstock, low reproductive performance, and easily cause diseases, resulting in additional losses during the breeding process.
