引言近十几年来,为弥补渔业资源的严重匮乏,世界上一些经济发达国家相继投入科研力量研究工厂化的先进养殖技术。这类技术一般以数学模拟为基础,建立养殖鱼生长的数学模型,寻找最佳生长条件作为可控参数与变量(如照明、温度、氧气和水位等)的函数,再由计算机辅助实施自动化的监控,达到最优化生产的目的。水产养殖有其自身的特殊性。在密集型的水产养殖工厂中,人们必须在技术环境中与生物系统打交道。由于缺乏灵敏的传感器和精密测量手段,在
Introduction In recent decades, in order to make up for the serious shortage of fishery resources, some economically developed countries in the world have successively invested in researching advanced industrialized farming techniques. Such techniques are generally based on mathematical modeling, establishing a mathematical model of farmed fish growth, looking for optimal growth conditions as a function of controllable parameters and variables such as lighting, temperature, oxygen and water level, and then computer-aided implementation of automation Monitoring, to achieve the purpose of optimizing production. Aquaculture has its own uniqueness. In intensive aquaculture factories, people have to deal with biological systems in a technical environment. Due to the lack of sensitive sensors and sophisticated measurement methods,
