Xenocypris davidi bleeker parent fish feed and preparation method thereof

Abstract

The invention discloses a xenocypris davidi bleeker parent fish feed which comprises the following components in parts by weight: 40-70 parts of water caltrop, 40-70 parts of stem or leaf of cattail, 10-20 parts of sanguisorba officinalis, 10-15 parts of radix isatidis, 5-10 parts of rheum officinale, 15-25 parts of peanut meal, 10-20 parts of soybean meal, 1-2 parts of erythrocin, 1-3 parts of egg shell powder and 1-2 parts of salt. The xenocypris davidi bleeker parent fish feed is simple in production process; by using aquatic plants as the main feed raw materials, the xenocypris davidi bleeker parent fish feed is rich in resource and low in cost; after treatment via the fermentation process, the contents of the protein and the crude fat in the feed are improved, the energy required by the growth and development of the parent fish is improved, the egg laying amount of the parent fish is increased and the reproductive capacity is improved; the traditional Chinese medicines such as the sanguisorba officinalis, the rheum officinale and the radix isatidis are matched with the erythrocin, the salt and the egg shell powder to strength the organism immunity of the parent fish and improve the immunity, so that the hemorrhagic disease can be fundamentally prevented and cured and the survival rate of the fry is improved; through the addition of the peanut meal and the soybean meal, the palatability is increased and the growth rate of the parent fish is improved.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to feed for broodstock of yellow-tailed pomfret and a preparation method thereof. Background technique [0002] Commonly known as yellow tail, yellow piece, yellow aunt, cucumber fish, etc., yellow-tailed pomfret is a small and medium-sized economic fish in the family Cyprinidae and subfamily Pomfret. It feeds on the detritus of higher aquatic plants. It is widely distributed in the Yangtze River, Qiantang River, Minjiang River and other water systems. It has been domesticated in ponds since the 1950s, and was successfully artificially propagated in the early 1960s. , artificial propagation is difficult, and it has not been able to form a batch of seed production. In recent years, due to overfishing and water pollution, the output of the yellow-tailed pomfret has dropped sharply, resulting in a shortage of market supply and promoting the development of artificial breeding....

AI Technical Summary

Problems solved by technology

[0002]The yellow-tailed pomfret is commonly known as yellow tail, yellow piece, yellow aunt, cucumber fish, etc. , live in the middle and lower layers of the water body, feed on floating diatoms, underwater humus, and detritus of higher aquatic plants, and are widely distributed in the Yangtze River, Qiantang River, Minjiang River and other water systems. They have been domesticated in ponds since the 1950s. At the beginning of the 1990s, artificial propagation was successful, but it was weak in physique and impatient, and it was difficult to artificially propagate it. It failed to form a batch of seed production. The decline has led to a shortage of supply in the market and promoted the development of artificial breeding. At present, the breeding of yellow-tailed pomfret broodstock is fed with fertilizer and water or with soy milk and other raw materials. This feeding method has relatively single feeding materials, difficult to balance nutrition, and there is waste of feed at the same time. large, serious water pollution and other problems, which in turn resulted in less spawning, low reproductive rate, poor stress resistance ability and low survival rate of yellow-tailed pomfret broodstock
