Abstract

The invention discloses a functional feed capable of restraining the gonadal development of micropterus salmoides 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, 13.35-14.85 kilograms of bentonite, 6.5-8 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 micropterus salmoides, but also can restrain the gonadal development of the micropterus salmoides on the basis that the character and the quality safety of the bred micropterus salmoides can be guaranteed, so that the weight growth of the micropterus salmoides 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 largemouth bass and a preparation method thereof. Background technique [0002] Largemouth bass (Micropterus salmoides), commonly known as California perch, is native to California, USA, and belongs to the order Perciformes and the sunfish family. Introduced into my country in the early 1980s, it has become one of the main varieties of freshwater aquaculture in my country due to its fast growth, few diseases, wide adaptability to temperature, less thorns, delicious taste and rich nutrition. However, largemouth bass will naturally mature and lay eggs from February to July every year. During this period, they will consume a lot of nutrients and energy, and their weight will grow slowly, which is very uneconomical for commercial fish farming. At present, there is no research report on controlling the growth and development of female largemouth bass gonads and eggs. Contents ...
