specific Embodiment approach 1

[0006] Specific embodiment one: a special feed for larval salmon in this embodiment consists of 30 to 52 parts of fish meal, 9 to 11 parts of casein, 7 to 9 parts of soybean meal, 4.5 to 5.5 parts of brewer's yeast, 11 to 5 parts by weight. 13 parts of corn gluten powder, 0.30-13.65 parts of wheat flour, 11.9-12.9 parts of fish oil, 0.45-0.55 parts of vitamin premix, 0.45-0.55 parts of mineral premix, 0.25-0.35 parts of choline chloride, 1.4-1.6 parts Soy lecithin, 0.9-1.1 parts of carboxymethylcellulose sodium (CMC) and 0-2.65 parts of Ca(H 2 PO 4 ) 2 mixed.

[0007] After feeding the feed of the present embodiment for larval salmon juveniles, the breeding survival rate increases by 15% to 35%, and the average weight gain rate increases by 140% to 220%.

[0008] The full-price artificial feed for juvenile trout in this embodiment has the effects of comprehensive nutrition, promoting the growth of juvenile trout, increasing immunity, etc., and is suitable for commercial pro...

Abstract

The invention relates to a special feed for juvenile fishes of brachymystax lenok, and relates to a special feed for juvenile fishes. The invention solves the problem of low cultivation survival rate caused by no special specific feed in an existing process of cultivating the juvenile fishes of the brachymystax lenok. The special feed for the juvenile fishes of the brachymystax lenok is prepared by mixing fish meal, casein, bean pulp, beer yeast, corn gluten meal, wheat flour, fish oil, vitamin premix, mineral matter premix, choline chloride, soyabean lecithin, sodium carboxymethylcellulose and Ca(H2PO4)2. After the juvenile fishes of the brachymystax lenok are fed by using the feed provided by the invention, the cultivation survival rate is increased by 15-30 percent, and the average weight gain rate is increased by 140-220 percent; and the special feed for the juvenile fishes of the brachymystax lenok has the effects of complete nutrition, promoting the juvenile fishes of the brachymystax lenok to grow, increasing the immunity and the like, and is suitable for commercialized production. The special feed for the juvenile fishes of the brachymystax lenok can be used for feeding the juvenile fishes of the brachymystax lenok.

Description

technical field [0001] The invention relates to a special feed for juvenile fish. Background technique [0002] Brachymystax lenok, belonging to Salmonidae, Salmoninae, and Brachymystax genus, is a rare indigenous cold-water fish in my country. In recent years, due to overfishing, deforestation, environmental pollution and other reasons, the population has gradually become scarce, and even in danger of extinction, it has become an endangered species. At present, the total artificial propagation of lemur salmon has been successful, and it is in the stage of large-scale breeding. In the process of large-scale breeding of lemur salmon, the breeding technology has been perfected, but there is no targeted commercial feed in the juvenile stage, so in the process of breeding lemur salmon juveniles can only be fed with rainbow trout feed, because it is not a dedicated Feed, various nutritional problems such as nutritional fin rot, enteritis, and vitamin deficiency appeared during ...
