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 invention relates to a nutrient-enhanced feed for shad broodstock and a preparation method thereof, belonging to the technical field of animal food. Background technique [0002] Shad is a rare and valuable economic fish in China. It is produced in the lower reaches of the Yangtze River. In 1988, it was listed as the first-level protected species in the list of China's national key protected wild animals. In recent years, due to overfishing, water environment pollution, and water conservancy construction damage to spawning grounds and feeding migration channels, the natural resources of shad have decreased sharply. At present, American shad is mostly imported from the United States and sold as shad. Along with the continuous increase of shad breeding scale, natural seed is far from being able to satisfy the needs of breeding industry. In the development process of shad artificial reproduction, the nutrition of broodstock directly affects the qu...

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.
