当前海洋牧场鱼类驯化以人工操作为主,鱼类自动驯化是建设高效海洋牧场运行模式的重要技术措施。根据部分鱼类具有趋声性或趋光性习性,设计了能定时播放声音和开启灯光、同时配合饵料定时定量供应的鱼类驯化装置。通过无线水下视频监控和定位通讯,实现对驯化效果监控和远程控制。实际试验中,以黑鲷鱼苗为研究对象,经过30 d的驯化,在播放声音和开启灯光后,黑鲷幼苗集群效果明显。试验结果表明该驯化装置的驯化效果明显,声音、光线、饵料供应、能量供应系统等工作正常,达到了设计要求,为海洋牧场鱼类自动驯化提供了有效的装备支撑。
At present, domestication of fish in marine pastures is dominated by man-made operations and automatic domestication of fish is an important technical measure to establish an efficient marine ranch operation mode. According to the tendency of some fish to have the trend of convergence or phototaxis, a fish acclimation device capable of regularly playing the sound and turning on the light while being regularly supplied with the bait is designed. Through wireless underwater video surveillance and positioning communications, to achieve the domestication effect monitoring and remote control. In the actual experiment, the black snapper was taken as the research object. After 30 days of domestication, the effect of the black sea bream seedling cluster was obvious after playing the sound and turning on the light. The results showed that domestication of domesticated device was obvious, sound, light, food supply, energy supply system and other work were normal, which met the design requirements and provided effective equipment support for marine domestication of marine pastures.
