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 its constitution was weak, irritable, and its anti-stress ability was poor. Artificial propagation was difficult, and it failed to form a batch of seed production. In recent years, due to overfishing and water pollution, yellow The output of the yellow-tailed pomfret has dropped sharply, and the market is in short supply, which has led to more and more artificial breeding of the yellow-tailed pomfret. In view of the low survival rate of the juvenile yellow-tailed pomfret in the current artificial breeding process, more researches have been done on the yellow-tailed pomfret. However, there are no reports on the adjustment of bait for juvenile yellow-tailed pomfret in order to improve the economic indicators such as survival rate and growth of juveniles.

Abstract

The invention discloses a special feed for xenocypris davidi bleeker juvenile fish. The special feed is prepared from the following components in parts by weight: 50-70 parts of alternanthera philoxeroides, 50-70 parts of eichharnia crassipes, 30-40 parts of peanut cakes, 30-40 parts of rapeseed cakes, 10-15 parts of crataegus pinnatifida, 10-15 parts of portulaca oleracea L, 2-6 parts of zanthoxylum nitidum, 2-6 parts of fructus cnidii, 3-7 parts of mints, 3-7 parts of ephedra sinica stapf, 1-3 parts of houttuynia cordata extracting liquid, 1-3 parts of dandelion extracting liquid and 1-2 parts of tenebrio molitor powder. According to the special feed for the xenocypris davidi bleeker juvenile fish, aquatic plants including alternanthera philoxeroides and eichharnia crassipes and the like serve as main raw materials of the feed and resources are abundant; a secondary fermentation process is used for treating so that the content of plant crude protein and crude fat in the feed can be greatly improved; meanwhile, animal protein tenebrio molitor powder is combined so that the nutrition is balanced; and the survival rate of the xenocypris davidi bleeker juvenile fish and the weight of adult fish are improved by feeding the fish with the special feed, the feed coefficient is reduced and the feed conversion rate is improved.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a special feed for juvenile 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. , poor anti-stress ability, difficult artificial propagation, and failed to form a batch of seed production. In recent years, due to overfishing and water environment pollution, the output of yellow-tailed pomfret has dropped sharply, and the market is in short supply, resulting in yellow-tailed pomfret. ...
