鱼虾混养模式下黄鳍鲷的咸淡水养殖技术研究

Astudy on the saltwater and freshwater aquaculture technology of Acan-thopagrus latus under the mixed culture model of fish and shrimp

由于在鱼虾混养模式下黄鳍鲷(Acanthopagrus latus)具有捕食行为,难以保障黄鳍鲷与虾类的和谐共生。为实现黄鳍鲷与虾类的和谐共生,开展了鱼虾混养模式下的黄鳍鲷咸淡水养殖技术研究。首先,针对养殖系统,确定了适合黄鳍鲷和虾类共生的养殖环境,设计了养殖池结构及内部布局。其次,饲养管理上设计了饲料配方和定时定量投喂方法。最后,采取病害防治、筛选和隔离病弱个体等生物安全措施,实现鱼虾混养模式下黄鳍鲷咸淡水的健康养殖。

Due to the predation behavior of Acanthopagrus latus in fish-shrimp mixed culture,it is difficult to ensure the harmonious symbiosis of fish-shrimp.In order to realize the harmonious symbiosis of fish-shrimp,the brackish water culture technology of Acanthopagrus latus under the mixed culture mode of fish and shrimp was studied.Firstly,according to the culture system,the culture environment suitable for the symbiosis of fish-shrimp was determined,and the structure and internal layout of the culture tank were designed.Secondly,feed formula and regular and quantitative feeding method are designed in feeding management.Finally,biosafety measures such as disease control,screening and isolation of sick and weak individuals were adopted to achieve healthy culture of Acanthopagrus latus in brackish water under the mixed culture mode of fish and shrimp.
