Nutrition reinforcement feed for female parent fishes of pelteobagrus fulvidraco and preparation method of feed

Abstract

The invention discloses a nutrition reinforcement feed for female parent fishes of pelteobagrus fulvidraco and a preparation method of the feed. The feed is prepared from full fat rice bran, red fish meal, sorghum meal, sunflower heads, squid meal, pumpkin powder, cuttlefish meal, cortex eucommiae, radix et rhizoma rhei, herb of lagochilus leiacanthus Fisch., VC lecithin, rape pollen, shrimp shells, a persimmon leaf extract, a pericarpium granati extract and a microecological preparation. Compared with the prior art, the nutrition reinforcement feed for the female parent fishes of the pelteobagrus fulvidraco and the preparation method of the feed have the advantages that the raw materials are processed in different ways, the structure that the feed cannot be absorbed by the female parent fishes and male parent fishes easily is changed, the nutrition of the feed is balanced, nutrition absorption of the female parent fishes in the culture and development period is improved, the physique of the female parent fishes of the pelteobagrus fulvidraco can be strengthened, anti-stress capacity and immunity of the female parent fishes of the pelteobagrus fulvidraco are improved, gonad breeding is promoted, the laid egg diameter is increased, and the fertilization rate and the emergence rate of fry of parent fishes are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a nutrient-enhanced feed for female broodstock of yellow catfish and a preparation method thereof. Background technique [0002] Yellow catfish is delicious, nutritious, and has certain medicinal value. Therefore, the market demand is large, its economic value is high, the market price is stable, consumers like it, and more and more people breed it. As a result, due to lack of experience, it often leads to poor water quality, poor dissolved oxygen, and poor physical fitness, especially problems such as high material ratio, serious seed rejection, and declining profits. Therefore, we should start from all stages of yellow catfish farming. According to different physiological needs in different periods, so that farmers can obtain higher profits, among which the reproduction of yellow catfish is the most important thing. Due to the large difference between female bro...

[0002] Yellow catfish is delicious, nutritious, and has certain medicinal value. Therefore, the market demand is large, its economic value is high, the market price is stable, consumers like it, and more and more people breed it. As a result, due to lack of experience, it often leads to poor water quality, poor dissolved oxygen, and poor physical fitness, especially problems such as high material ratio, serious seed rejection, and declining profits. Therefore, we should start from all stages of yellow catfish farming. According to different physiological needs in different periods, so that farmers can obtain higher profits, among which the reproduction of yellow catfish is the most important thing. Due to the large difference between female broodstock and male broodstock, they are usually cultivated separately. Female broodstock is relatively weak. It is prone to diseases and seriously affects reproductive performance and spawning quality. Therefore, it is necessary to improve the reproductive ability of female broodstock by improving the feed, so as to achieve higher economic benefits
