Abstract: Xiapu Aquaculture Technology Extension Station and Fujian Jiqinghe Ocean Development Limited Liability Company jointly carried out the experiment of turnover culture technique of Pyropia haitanensis in Dongbi Sea area. The total culture area was 6 hm2. The result showed that the turnover culture technique of pyropia was a culture method had the advantages of simple structure, convenient operation, energy saving and environmental protection, low production cost, high economic efficiency, wide application range, high product quality. The production output of the turnover culture of pyropia was 1100 kg/200 m2. The output value was ￥10550/200 m2. The cost of production was ￥1150/200 m2. The profit was ￥9400/200 m2. This paper introduced the turnover culture technique and summarized the experience and deficiency of this experiment. We hoped this paper could provide us a solid foundation for the innovation of culture technique and large scale application of turnover culture technique for Pyropia in the future.
