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.
