2001年天津市汉沽区进行了南美白对虾的高产养殖试验,通过技术人员的亲临指导,和虾农的精心管理,试验取得了平均亩产410kg,亩均产值13940元,亩纯利润7380元的好成绩,这在淡水养殖普遍效益较低的今天,无疑对养殖品种的结构调整起到推动作用。广大渔民对养殖白对虾的热情非常高,笔者亲自参与了这一高产养殖试验。为使这一新品种能够健康持久的发展,必须不断总结经验教训,使养殖技术日趋成熟,精益求精。我们通过今年的试验,总结了在南美白对虾养殖管理中应注意的几个问题,供广大同行参考。 In 2001, Hangu District, Tianjin carried out high-yielding experiment of white shrimp Penaeus vannamei. Through the in-depth guidance of technicians and careful management of shrimp farmers, the average yield of 410kg per mu, average output value of 13940 yuan per mu, net profit of 7380 yuan Good grades, which are generally low in freshwater aquaculture today, undoubtedly promote the structural adjustment of cultured species to play a catalytic role. The majority of fishermen on the culture of white prawn enthusiasm is very high, the author personally involved in this high-yielding breeding test. In order to make this new breed grow healthily and sustainably, we must constantly summing up the experience and lessons so that breed technology can be matured and keep improving. Through this year’s experiment, we summarize several problems that we should pay attention to in the management of P. vannamei culture for the reference of the majority of peers.
