摘要： An SNP molecular marker for weight gain trait selection and genetic sex identification of Ictalurus punctatus as well as a screening method and application of the SNP molecular marker are provided. At least one of 17 SNP molecular markers for weight gain trait selection of Ictalurus punctatus and a molecular control means for genetic sex and weight gain trait selection and control of Ictalurus punctatus are further provided. Efficient and scientific identification of Ictalurus punctatus is achieved by means of simple PCR reactions and nucleic acid test strips, and the accuracy rate reaches 100%. A traditional agarose gel electrophoresis method is not used in the whole identification process, the cumbersome steps of gel preparation and running electrophoresis are omitted, nucleic acid dyes are not used, and the experimental process is safe and environmentally friendly.

摘要： A traditional Chinese medicine polysaccharide extract freeze-drying protective agent, a direct-to-vat starter and preparation methods thereof are disclosed, which belong to the technical field of feed starter. The compound traditional Chinese medicine polysaccharide extract freeze-drying protective agent includes Poria cocos polysaccharide extract, Atractylodes macrocephala polysaccharide extract, Radix codonopsis polysaccharide extract, L-tyrosine, α-cyclodextrin and polyethyleneimine. Its application in the freeze-drying protection of direct-to-vat starter of aquatic fermentation feed can reduce the damage to the cells caused by freeze-drying, improve the survival rate of the cells in the starter after freeze-drying, effectively prolong the storage period of the starter, and ensure that the fermentation activity remains at a high level during storage.
