对于淡水养鱼来说,同饲料台安装在一起的分散投饲机是最有发展前途的。为了测量鱼的声电活度,在饲料台区域设有仪表系统(图1)。用这样的设备分散投饲,饲料台上没有饲料损失,并且在鱼摄食活度高时,能够在饲料台上区用水中听音器或者天线记录它。投饲之后,用同样的测量仪器记录鱼对饲料的适口性。这样可以检验 For freshwater fish farming, the disperser that is installed with the feed table is the most promising. In order to measure the acoustics of the fish, an instrumentation system is located in the area of ​​the feed table (Figure 1). Feeding with such equipment, there is no loss of feed on the feed table, and it can be recorded on the feedboard area with a water-microphone or antenna while the fish is eating well. After feeding, use the same measuring instrument to record the palatability of the fish to the feed. This can be tested
