为半滑舌鳎（Cynoglossus semilaevis Günther）的集约化养成提供基础数据，在工厂化循环水养殖模式下，以处于快速生长期的大规格鱼种（0.64±0.063） kg为研究对象，设置4个密度梯度组，检测半滑舌鳎的生长及肉质相关指标，结果表明：a. 实验共进行7个月，半滑舌鳎在循环水养殖模式下的总成活率为88.01 %～93.34 %，总增重率为139.69 %～191.09 %，且随着养殖密度降低，其成活率呈下降趋势，生长速度、肥满度呈上升趋势，半滑舌鳎生长激素分泌浓度为2.522～2.862 4 μg/L，各养殖密度组的生长激素随养殖密度下降前期呈升高趋势，后期呈下降趋势；b. 各养殖密度组水分、灰分、粗蛋白、粗脂肪、氨基酸和脂肪酸含量随养殖密度变化均没有规律性变化；c. 本实验条件下，循环水养殖模式X2组即初始放养210条的处理组取得了最佳的养殖效果，月平均成活率为98.72 %，月增重为0.152 6 kg/条，经7个月的养殖，可达到23.03 kg/m3的单位产量。本实验说明半滑舌鳎在循环水养殖模式下具有很好的适应性，其生长及营养成分均处于较好的状态，同时也说明循环水养殖模式可以极大地发掘半滑舌鳎的养殖潜力，是适合半滑舌鳎集约化养殖的一种具有优势的养殖模式。

In order to collect more basic data of intensive aquaculture of Cynoglossus semilaevis Günther， 4 groups of different stocking densities were set up in industrial recirculating aquaculture system， the adult fish in rapid growth period (0.64±0.063) kg were observed， the parameters of growth and quality in muscles were detected. The results were shown as follows. a. The experiment continued for 7 months， the survival rate of Cynoglossus semilaevis Günther in recirculating aquaculture mode was in 88.01 %～93.34 %， weight gain rate was 139.69 %～191.09 %. With the decrease of stocking density， survival rate was on a declining curve， while growth rate and fatness were on a rising trend. The concentration of growth hormone was 2.522～2.862 4 μg/L， which was on a rising trend in earlier stage and then on a declining curve in later stage with the decrease of stocking density. b. There is no regular change of moisture， ash content， crude protein， crude fat， amino acid and fatty acid with the change of stocking density. c. In this experimental condition， the group whose intial stocking density is 210 got the best culture effect； the average survival rate per month was 98.72 %； the average gaining in weight per month was 0.152 6 kg/pcs； after 7 months breeding， the specific yield reached 23.03 kg/m3. This study showed that Cynoglossus semilaevis Günther has a good adaptability in industrial recirculating aquaculture， and the growth and quality in muscles were all in a better condition. It also showed that industrial recirculating aquaculture can greatly develop the culture potential of Cynoglossus semilaevis Günther， which was a preponderant culture mode for intensive aquaculture of Cynoglossus semilaevis Günther.
