对分区水产养殖系统技术(PAS)研究,有望大幅度提升单位面积的产鱼量,同时降低90%的单位产量耗水量,可在无法进行传统水产养殖的区域建立PAS系统。PAS系统的开放池不养鱼,只用作废水处理单元,深度0.6 m。开放池沿长度方向设多个挡板,保持水流循环。鱼养殖在约1.2 m深的水道内,由水泥墙分区,水道末端用网阻拦。池塘边设控制房,持续监控含氧量、pH、温度等参数,叶轮搅拌装置对水质进行调控。
The study of zoning aquaculture system technology (PAS) is expected to significantly increase fish production per unit area and reduce water consumption by 90% per unit of production to establish a PAS system in areas where conventional aquaculture is not possible. The open pond of the PAS system does not feed fish and is only used as a wastewater treatment unit with a depth of 0.6 m. Open pool along the length of the direction of a number of baffles to maintain water circulation. Fish are cultured in waterways about 1.2 m deep, partitioned by concrete walls, and blocked by nets at the end of the watercourse. The pond side of the control room, continuous monitoring of oxygen content, pH, temperature and other parameters, impeller mixing device to regulate water quality.
