海洋牧场鱼类驯化装置设计与试验

Design and experiment of fish domestication equipment for ocean ranching

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。

The fish domestication at present is mainly operated manually in ocean ranching. Automatic fish domestication is an important technical measure to construct efficient operating mode. A new type of fish domestication equipment is designed according to the fish＇ s sensitivity to sound or light. It involves the function of timing control of sound and light as well as feed supply corresponding with the requirement. A wireless underwater video monitoring and positioning instrument is designed to supervise the domestication effect and realize positioning function. Taking Sparus macrocephalus fries as the research object, after 30 days of domestication, Sparus macrocephalus fries cluster obviously after starting the sound and light. Experiment results show the domestication effect is prominent and the whole system is designed reasonably. The sound, light, feed supply and energy system work regularly. The system reaches the design requirements which supplies an effective equipment for automatic fish domestication in ocean ranching.
