AbstractTo investigate the domestication effciency of feed Siniperca chuatsi in the domestication model of industrial circulating water，anearly-stage Siniperca chuatsi was conducted inarectangular training tankover52days. Growth performance indicators，includingsuvival rate of Siniperca chuatsi，were measured，and economic benefits were analyzed.Theresults showedthat after domesticationthefinal specificationoffeed Siniperca chuatsi was 43 individuals/kg， with a survival rate of 90.72% ，weight gain rate of 924.67% ，and feed conversion ratio of 1.O7. Economic benefits analysis revealed a net profit of 78 832 yuan， with an overall break-even survival rate exceeding 42.43% . In conclusion，this training model offers advantages suchas ashort cycle，simpleoperation，strong controllability，high survival rate，andsignificant economic benefits，makingit suitable for broader application in production.
