Abstract

The invention discloses a functional feed capable of restraining the gonadal development of pseudosciaena crocea and a preparation method of the functional feed. The formula of the fish feed comprises the following substances based on 1000 kilograms of the fish feed: super steam fish meal, flour, cottonseed meal, fish oil, corn protein powder, soybean meal, beer yeast, vital wheat gluten, phosphatide oil, squid soluble paste, hemoglobin meal, calcium dihydrogen phosphate, 3.35-5.35 kilograms of bentonite, 6-8 kilograms of castor seeds, trace elements of special fishes, a choline base additive, a mildewproof agent, complex vitamins of special fishes, a vitamin C type additive, an antioxidant, myo-inositol and carnitine. The fish feed disclosed by the invention not only can meet the normal growth requirements of the pseudosciaena crocea, but also can restrain the gonadal development of the pseudosciaena crocea on the basis that the character and the quality safety of the bred pseudosciaena crocea can be guaranteed, so that the weight growth of the pseudosciaena crocea is facilitated, and the breeding economic benefits are improved.

Description

technical field [0001] The invention relates to a functional feed for inhibiting gonad development of large yellow croaker and a preparation method thereof. Background technique [0002] Large yellow croaker (Pseudosciaenacrocea R.) belongs to Perciformes, Totoaceae, and Yellow croaker. Its meat is delicious, nutritious, and has a large market demand. At present, it has become the main marine fish species in cage culture in coastal areas of Zhejiang, Guangdong, and Fujian. one. However, during the breeding process of large yellow croaker, large yellow croaker ovulates due to natural maturation in March-May and October-November each year, during which time a large amount of nutrition and energy will be consumed, and the weight gain will be slow, which is very difficult for commercial fish farming. Uneconomical. At present, there is no research report on controlling the growth and development of female large yellow croaker gonads and eggs. Contents of the invention [000...
