养鱼场自动化工作至为重要,其中极需完善化的是幼鲟计数装置。现今使用的计数方法存在缺点:一是精确度不高,二是劳动繁重。从现有计数技术中分析,超声波计数法利用鲟鱼反射和吸收声波原理为佳。电视技术计数方法的主要缺点是计算误差 The automation of fish farms is of paramount importance, with juvenile sturgeon counting devices in great need. There are disadvantages to the counting method used today: one is that the accuracy is not high, and the other is heavy labor. From the existing counting technology analysis, ultrasonic counting method using sturgeon reflection and absorption sound waves better. The main disadvantage of the television technique counting method is the calculation of errors
