Abstract

A special feedstuff used for hucho taimen larvae relates to a fish feedstuff. The invention solves the problems of low growth speed and high death rate of hucho taimen by feeding the hucho taimen withrainbow trout feedstuff. The hucho taimen special feedstuff comprises the following components in weight percentage: 2-5 percent beer yeast, 2-6 percent wheat-middling, 2-8 percent spray drying bloodflour, 60-70 percent fish flour, 10-20 percent fish oil, 1-4 percent soybean lecithin, 0.2-0.8 percent sodium alginate, 0.01-0.05 percent L-carnitine, 0.05-0.2 percent KCL, 0.02-0.1 percent inositol,0.02-0.07 percent enzyme preparation, 0.01-0.04 percent high stability VC, 0.1-0.5 percent magnesite, 0.01-0.05 percent antioxidant, 0.05-0.02 percent Kemei, 0.8-1.5 percent zeolite. Compared the special feedstuff with the imported rainbow trout feedstuff, by feeding the hucho taimen with the special feedstuff, the survival rate of the hucho taimen can reach above 95% after 4 weeks, and the survivalrate of the hucho taimen can reach above 92% after 8 weeks; the average weight is increased by 18.35%, and the weight gain rate is improved by 9.49%.

Description

technical field [0001] The invention relates to a fish feed, in particular to a special feed for juvenile fish. Background technique [0002] Zheluo fish (Taimen; Zheluo salmon, Xinjiang big red fish) is delicious and pink in color. It is one of the rare fishes in Northeast and Northwest China. At present, there is no special feed designed according to the nutritional needs and digestive physiological characteristics of salmon. In production, rainbow trout feed has to be used to feed the salmon, but the rainbow trout feed is designed according to the nutritional characteristics of the rainbow trout, which cannot fully meet the nutritional needs of the salmon, resulting in slow growth and high mortality. Contents of the invention [0003] The invention aims to solve the problems of slow growth and high death rate of the tilapia caused by feeding the tilapia with rainbow trout feed at present. In the present invention, the special feed for crocodile larvae is mainly ~5 par...
