世界上特别是日本和美国对于虾类的大量需要使得菲律宾将传统的养鱼池改造为带有增氧等设备的现代化养虾池。采取这一措施的结果是,池塘产量大增。在为期约120天的一茬生产中,每公顷产量由300公斤猛增至8000公斤。 The massive demand for shrimp in the world, especially in Japan and the United States, has transformed the Philippines’ traditional fish pond into a modern shrimp pond with equipment such as aeration. As a result of this measure, pond production has soared. During the first crop of about 120 days, the yield per hectare soared from 300 to 8000 kg.
