天津的淡水养鱼,基本上仍是沿用传统的养鱼方式,在渔业战线上贯彻执行毛主席提出的“农业的根本出路在于机械化”的伟大指示,是我们面临的艰巨任务。淡水养鱼必须逐步向机械化、自动化迈进,尽量采用先进技术,使产量成倍的增长,才能适应日益发展的社会主义建设的需要。流水高密度养殖非洲鲫鱼的试验就是力求达到上述目的的一项尝试。采用流水高密度养殖方式,可以在小水体中获得高于一般坑塘十倍至几十倍的产量。它占地少水体小,打破了几千年来必须有河有坑才能养鱼的传统观念,使渔业生产冲破坑塘河道的束缚,向更广阔的区域发展。由于采用的是工业化养 Freshwater fish farming in Tianjin basically still follows the traditional way of fish farming. It is a daunting task for us to implement Chairman Mao’s “great solution to the fundamental road to agriculture mechanization” proposed by Chairman Mao on the fishing front. Freshwater fish culture must gradually move toward mechanization and automation, try its best to adopt advanced technologies to double the output and adapt to the needs of the ever-developing socialist construction. High-density running aquaculture of African crucian carp is an attempt to achieve these goals. The use of high-density aquaculture, can be obtained in small bodies of water more than ten times the general pit to dozens of times the production. It occupies a small area of ​​small water bodies, breaking the traditional concept of having potholes and pits for fish farming for thousands of years, breaking the shackles of the fishery production in the Kengtang River to a wider area. As a result of the industrialization of culture
