由于世界性对虾暴发病毒病的蔓延,使对虾养殖业步入了一个低谷,这就使得人们对传统的对虾养殖方式开始进行重新的思考。青岛海洋大学的科技工作者们研究采用海水陆基围隔实验的方法,探讨了以对虾为主,中国对虾、罗非鱼、缢蛏投饵混养的最佳结构、N、P的利用率等。并比较了其养殖效果。从实验结果看,尽管对虾、罗非鱼与缢蛏的三元混养增加了操作和管理的难度,但在生态和经济效益上与虾鱼、虾贝混养相比都为最佳,充分显示出多元混养的优越性,它代表了今后一种虾池混养的主方向,具有较好的应用前景。由于其具有兼顾生态和经济效益的特点。如果能在生产上大规模推广应用,可能会是对虾养殖业走出当前困境的一个较好途径。
The shrimp farming industry has reached a low point due to the spread of virus outbreaks in shrimp in the world, which has given rise to a rethinking of the traditional ways of shrimp farming. Qingdao Ocean University, the scientific and technological workers to study the use of sea-water landfill experiments to explore the main shrimp, prawn, tilapia, bait bait polyculture best structure, N, P utilization rate . And compare the breeding effect. From the experimental results, although the prawn, tilapia and catfish ternary polyculture increased the difficulty of operation and management, but in the ecological and economic benefits compared with shrimp, shrimp shell polyculture compared to the best, fully demonstrated Out of the advantages of multiple polyculture, which represents the main direction of a pond shrimp polyculture, with good prospects. Because of its ecologically and economically balanced features. If large-scale popularization and application in production may be shrimp farming industry out of the current predicament of a better way.
