Production technology of feed capable of promoting parent fish gonadogenesis of xenocypris davidi and application of feed capable of promoting parent fish gonadogenesis of xenocypris davidi

Abstract

The invention discloses a production technology of a feed capable of promoting parent fish gonadogenesis of xenocypris davidi and an application of the feed capable of promoting parent fish gonadogenesis of xenocypris davidi. The production technology of the feed capable of promoting parent fish gonadogenesis of xenocypris davidi comprises the following steps: (1) weighing weight fish meal, soybean meal, rapeseed meal, cottonseed meal and flour, carrying out mixed crushing, and carrying out stirring for 20-30 minutes so as to obtain a mixture 1; (2) weighing fish oil, lecithin, a vitamin premix, a mineral salt premix, calcium dihydrogen phosphate, chloride choline and zeolite powder, carrying out mixing, and carrying out stirring for 10-20 minuts so as to obtain a mixture 2; (3) weighing aself-made adhesive and wall-broken pollen, and carrying out uniform mixing so as to obtain a mixture 3; and (4) mixing the mixture 1, the mixture 2 and the mixture 3 at a mass ratio of 50 to 5 to 2,and carrying out uniform mixing at 25-28 DEG C so as to obtain the feed capable of promoting parent fish gonadogenesis of xenocypris davidi. Being used for feeding parent fishes of xenocypris davidi,the feed prepared by the production technology is capable of promoting female and male substance accumulation in bodies of cultured xenocypris davidi so as to promote gonadogenesis. The production technology has the advantages of simple operations, relatively small nutrient loss in feed and so on; and thus, the feed capable of promoting parent fish gonadogenesis of xenocypris davidi is suitable for large-scale production and application.

Description

technical field [0001] The invention relates to a fish feed production process, in particular to a feed production process and application for promoting gonad development of broodstock of yellow-tailed pomfret, belonging to the field of fish breeding. Background technique [0002] Yellow-tailed pomfret (Xenocypris davidi Bleeker,) is commonly known as yellow tail, yellow piece, yellow aunt, cucumber fish, etc. It is widely distributed in the Yangtze River, Pearl River and Yellow River basins in my country. It has the advantages of wide food habit, fast growth, large amount of eggs, fast multiplication, strong disease resistance, and easy fishing. It is an ideal fish for natural multiplication in large water surfaces of rivers, lakes and reservoirs, and it is also an excellent species for mixed culture in ponds. In recent years, due to factors such as overfishing, sand pumping and dam building, its ecological environment has deteriorated, and its population has also been gr...
