国外开展工业化养鱼已有30多年,工业化养鱼技术在提高鱼类产量、降低能耗、节约水源等方面都取得了非凡的成就。以下介绍几种工业化养鱼新技术: 1.闭式循环水养殖系统 由于世界性水资源短缺,各发达国家基本上不再发展耗水多的流水养鱼,而是重点开发闭式循环水养殖设备,进一步改善水处理技术,减少换水量。工业化养鱼将主要采 Industrialized fish farming has been carried out for more than 30 years in foreign countries. Industrialized fish farming has made extraordinary achievements in raising fish production, reducing energy consumption and saving water. The following describes several new technologies for industrial fish farming: 1. Closed-loop recirculation aquaculture system Due to the worldwide shortage of water resources, developed countries are basically no longer developing water-consuming fish culture, but rather focus on the development of closed-loop recirculating aquaculture Equipment, to further improve water treatment technology, reduce water change. Industrial fish farming will be the main mining
