工业化养鱼在国外已有约30年的发展历史。随着科学技术的进步,各国工业化养鱼规模日益扩大,新型养殖技术不断涌现。 工业化养鱼将主要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,减少日换水量。 普及应用纯氧增氧技术。80年代丹麦和德国都成功地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,大大提高了单位水体的鱼产量。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
Industrial fish culture in foreign countries have about 30 years of development history. With the progress of science and technology, the scale of industrialized fish culture in various countries is expanding day by day, and new farming techniques are emerging. Industrial fish culture will mainly use closed-loop recirculation aquaculture system. Due to the worldwide shortage of water resources, developed countries have focused on the development of closed-loop recirculating aquaculture equipment to further improve water treatment technologies and reduce the daily water exchange rate. Universal application of oxygen oxygen technology. In the 1980s both Denmark and Germany successfully designed and built aquaculture equipment that uses liquid oxygen to aerate fish ponds and biofilters and greatly increased fish production per unit of water. The United States and Sweden and other countries developed a pressure oscillation absorption system oxygen device can be used for fish
