海洋牧场智能化浮式聚鱼装备研发与现场试验

海洋牧场是减缓我国近海渔业资源衰退,实现可持续利用的重要抓手,鱼类行为控制是海洋牧场高效运行的四大关键技术之一。为满足海洋牧场系统化渔业生产和管理的需要,研制了一种可业务化运行的智能化浮式聚鱼装备。该装备以无线网桥为通信核心,运用继电器组分别控制水下监控系统、声音驯化系统、定量投饵系统、传感器等,解决了开放式海域鱼类行为的驯化与控制问题。为解决驯化中出现的自相残杀和鱼类生长的"马太效应",研发了柔性分级驯化栅,通过使用前后效果的对比分析发现能够明显提高驯化效果。所研发装备在象山港海洋牧场以黑鲷为对象进行了全过程试验,针对核心区和周边三个对比区进行了长周期调查,现场试验结果表明了其有效性,能够有效提升鱼类行为控制水平,为最终实现海洋牧场的高效运行提供了坚实支撑。

Research and experiment of intelligent floating fish accumulating equipment for ocean ranching

Ocean ranching is a vital method to slow the decline of costal fisheries resources and achieve its sustainable utilization. Fish behavior control is one of the four key technologies for ocean ranching efficient operation. To meet the requirement of fishery production and management in ocean ranching, an intelligent floating fish accumulating equipment that can long-term run is developed. Take wireless network bridge as the communication centre and electric relay as the switch to control the underwater video supervising subsystem, sound taming subsystem, quantitative baiting subsystem and sensor, which solves the fish behavior control and taming problem in opening ocean area. To solve the phenomena of destroying each other and "Matthew effect" in fish growing process, flexible classified mesh is designed and its application has dramatically improved the taming effect. Take sparus macrocephlus as the research object, the equipments developed have been applied in the practical ocean ranching. Long term investigation to the core area and 3 comparative areas has been conducted and the result shows its validity, which improves the fish behavior control ability and provides solid support for the high efficient operation of the ocean ranching.
