摘　　要：为探索适合刀鲚的池塘养殖新模式,分别在淡水和半咸水环境下开展了1^(+)龄刀鲚与暗纹东方鲀的混养试验。试验结果表明,刀鲚与暗纹东方鲀在半咸水环境下混养,在产量、成活率、平均出塘规格等方面具有明显优势,当刀鲚放养密度为3 000尾/hm^(2)时,单位面积产量最高可达116.70 kg/hm^(2),该塘刀鲚成活率为68.16%,平均出塘规格可达57.11 g,体质量在50 g以上的比例为61.66%。To explore a new pond culture model suitable for Coilia nasus,a polyculture experiment of Takifugu obscures with one-year-old C.nasus was carried out in fresh and brackish water environments.The results showed that C.nasus and Takifugu obscures mix-cultured in brackish water had obvious advantages in yield,survival rate and the average body weight at harvest.When the stocking density of C.nasus was 3000 tail/hm^(2),the yield per unit of C.nasus could reach 116.70 kg/hm^(2),the survival rate was 68.16%,the average body weight at harvest was 57.11 g,and the proportion of body weight above 50 g was 61.66%.
