Problems solved by technology

[0003] Whitefish production has relatively high requirements on water quality. Feed for juvenile whitefish larvae is easy to pollute water quality when feed is used. The water quality after pollution is not conducive to the survival of larvae whitefish. At the same time, feed granulation needs to be driven by multiple sets of equipment, which increases the cost of use. , In addition, granulation is not convenient for timely drying, and other equipment needs to be added for drying

Abstract

The invention discloses feed for improving survival rate of juvenile whitefish, and relates to the field of aquaculture feed. The feed capable of increasing the survival rate of juvenile whitefish is prepared from the following components in parts by weight: 33 to 46 parts of peanut cakes, 44 to 65 parts of bean cakes, 34 to 45 parts of rape seed cakes, 55 to 76 parts of sweet corn, 10 to 20 parts of bran, 3.6 to 5 parts of enzymolysis fish protein, 0.2 to 1.6 parts of betaine, 0.5 to 1.5 parts of taurine, 0.35 to 0.5 part of hydroxyproline, 0.1 to 0.3 part of glycine, 0.1 to 0.3 part of alanine, 1.5 to 2.8 parts of monocalcium phosphate, 0.3 to 1.5 parts of choline chloride. 0.5-1.3 parts of complex vitamins, 0.5-1.3 parts of complex trace minerals, and 400-600 parts of water. According to the feed, protein sources of the raw materials are balanced through the lycine, the taurine, the hydroxyproline glycine, the alanine and the monocalcium phosphate, comprehensive absorption of digestive tracts of whitefishes is facilitated, absorption of the whitefishes is facilitated, feed waste is avoided, water quality is guaranteed, and the survival rate of the juvenile whitefishes is increased; and in addition, the preparation process is simple and beneficial to preparation.

Description

technical field [0001] The invention relates to the field of aquaculture feed, in particular to a feed for juvenile whitefish that improves the survival rate. Background technique [0002] There are 16 species of white fish, which are endemic to our country. It is mainly distributed in Gaoyou City, Jiangsu Province (Gaoyou Lake Whitefish), northwest Yunnan and Qionghai, Sichuan. The areas where these fishes are distributed are often relatively narrow, and often one species is only found in one lake or one reservoir. It is Qiao Yu, which grows in rivers and lakes. It is white in color, with a happy head, and the big ones are six or seven feet long. It tastes beautiful. [0003] Whitefish production has relatively high requirements on water quality. Feed for juvenile whitefish larvae is easy to pollute water quality when feed is used. The water quality after pollution is not conducive to the survival of larvae whitefish. At the same time, feed granulation needs to be drive...
