This invention discloses an artificial breeding method for yellow catfish, relating to the field of animal husbandry technology. The breeding method includes: (1) artificially hybridizing yellow catfish and long-snout catfish as parents to obtain a binary hybrid fish; (2) artificially hybridizing the binary hybrid fish and yellow catfish as parents to obtain a ternary hybrid yellow catfish. The breeding method of this invention, through specific selection and matching of hybrid parents, enables the excellent genetic resources of the three parents to be inherited synchronously and stably during the ternary hybridization process, thereby stably obtaining a new fish variety with fast growth rate, good stress resistance, high fish meat quality and good disease resistance, which is of great significance for ensuring the long-term supply of high-quality aquatic products and promoting the high-quality development of fisheries.

The application discloses a kind of for sheep MSTN And SOCS2 The sgRNA of gene cytosine base editing and application thereof, the sgRNA includes nucleotide such as any one or several of SEQ ID NO.1~4.This application is respectively designed sgRNA guide sequence for sheep MSTN And SOCS2 Gene, introduce stop codon in target site using CBE system, select sgRNA guide sequence and its combination from which can efficiently target sheep MSTN And SOCS2 Gene, carry out gene editing efficiency verification on cell, and successfully obtain MSTN And SOCS2 Double gene editing goat by prokaryotic embryo microinjection technology, and gene editing sheep shows muscle fiber thickening, and fast growth rate.This application establishes a set of efficient, precise double gene editing technology system, provides key breeding material and technical support for quickly cultivating muscle developed, fast growth meat sheep new variety.
