摘　　要：为探索种养结合的美洲鲥生态养殖新模式,选取平均体长、体质量分别为2.70 cm、0.36 g的1龄美洲鲥和平均体长、体质量分别为26.09 cm、279.52 g的2龄美洲鲥开展草塘围网养殖试验,监测其生长性能,并对该模式的养殖成本和经济效益进行分析。试验结果:经过190 d饲养,1龄美洲鲥的终末平均体长、体质量分别为16.28 cm、56.62 g,2龄美洲鲥的终末平均体长、体质量分别为33.58 cm、635.98 g;1龄和2龄美洲鲥的体长特定增长率分别为(0.95±0.01)%/d和(0.13±0.03)%/d,体质量特定增长率分别为(2.67±0.02)%/d和(0.44±0.10)%/d;1龄和2龄美洲鲥的养殖成活率分别为87.5%和64.6%;2龄美洲鲥养殖的平均利润为9.15万元/hm^(2)。结果表明,美洲鲥草塘围网生态养殖模式能改善养殖水体环境,有利于美洲鲥生长,提高养殖经济效益,是值得推广的绿色生态健康养殖新模式。To explore a new model of ecological culture that combines planting and breeding of Alosa sapidissima,one-and two-year-old A.sapidissima were selected for experiment.The growth performance of A.sapidissima and the water quality were monitored,and the breeding cost and economic benefits of this model were analyzed.The results show that after 190 days of rearing,the average final body length and weight of one-year-old A.sapidissima were 16.28 cm and 56.62 g,respectively,and the average final body length and weight of two-year-old A.sapidissima were 33.58 cm and 635.98 g,respectively.The specific growth rate of one-and two-year-old A.sapidissima were(0.95±0.01)%/d and(0.13±0.03)%/d,respectively,and the specific weight gain rate of one-and two-year-old A.sapidissima were(2.67±0.02)%/d and(0.44±0.10)%/d,respectively.The survival rates of one-and two-year-old A.sapidissima were 87.5%and 64.6%,respectively,and the average profit of two-year-old A.sapidissima was 91500 CNY/hm^(2).In conclusion,the model of A.sapidissim a in grass pond with purse seine can improve water environment,promote the growth of A.sapidissima,and improve the economic benefits of culture.It is a new model of green,ecological,and healthy culture worth promoting.
