随着科学技术的进步,工业化养鱼技术不断发展,不少国家在提高水产品产量和降低能耗、节约水源等方面不断取得新的成就。 1.采用闭式循环水养殖系统。由于世界性水资源短缺,发达国家越来越重视开发闭式循环养殖设备,进一步改善水处理技术,减少日换水量。 2.提高增氧技术。丹麦和德国等国设计和建造了使用液氧向养鱼池和生物过滤器增氧的养殖设备,大大提高了单位水面的鱼产量。美国和瑞典等国研制了压力振荡吸收系统制氧装置,可用于鱼类养殖直接生产含量为85％～95％的富氧,从而使工业城市的养殖场也 With the progress of science and technology, industrialized fish farming technology continues to evolve. Many countries continue to make new achievements in raising the output of aquatic products, reducing energy consumption and saving water. 1. Closed loop water aquaculture system. Due to the worldwide shortage of water resources, developed countries have paid increasing attention to the development of closed-loop aquaculture equipment to further improve water treatment technologies and reduce daily water exchange. 2. Increase oxygen technology. Countries such as Denmark and Germany designed and built aquaculture equipment that uses liquid oxygen to aerate fish ponds and biofilters and greatly increase fish production per unit of water. The United States and Sweden and other countries developed a pressure oscillation absorption system oxygen plant can be used for direct production of fish farming containing oxygen content of 85% to 95%, so that the industrial city farms are also
