[目的]提高虱目鱼和南美白对虾的养殖成活率,并获得较为稳定的养殖效果.[方法]通过优化虱目鱼与南美白对虾高效生态混养的投放规格、顺序、密度比等,利用二者生态位差异,提高水体利用率.同时,在池塘生态系统中引入水生植物空心菜等,优化微生态制剂使用方法.[结果]收获虱目鱼平均规格0.52 kg/尾,单产5010 kg/hm2,成活率43%;收获南美白对虾平均规格90只/kg,单产6795 kg/hm2,成活率51%.[结论]生态混养模式能够显著提高单位水体养殖效率,同时实现养殖生态环保、达标排放的目的.%[Objective]To improve the survival rate of Chanos chanos Forskal and Penaeus vannamei and obtain stable breeding effects.[Method] Through optimizing the specifications,order and the density ratio of C.chanos Forskal and P.vannamei in ecological efficient polyculture,ecolog-ical niche differences of the two species were utilized and the utilization rate of aquaculture water were improved.Aquatic plants such as Ipomoea aquatica Forsk were introduced in pond ecosystem and the usage methods of microecological agents were optimized.[Result]The average size of harvested C.chanos Forskal was 0.52 kg/ ind.,the yield was 5 010 kg/hm2,the survival rate was 43%.The average size of harvested P.van-nameiwas 90 ind. /kg,the yield was 6 795 kg/hm2,the survival rate was 51%.[Conclusion]The ecological polyculture model could significantly improve the aquaculture efficiency of unit water quality,and realize the goal of ecological raising and standard emission.
