Abstract: A comprehensive monitoring system was developed for real-time acquiring mariculture environmental information and real-time observation of cultured living beings and behavior in sea ranching.In the system,all sensors and other components were carried on a homemade buoy platform,and some key technical issues were effectively resolved including multi-sensor signals data parallel acquisition,remote transmission of data and underwater videos and camera waterproofing&O-ring sealing.The trials showed that simultaneous calling multiple serial ports for data collection ensured timeliness and accuracy of multiple water quality parameters data acquisition.Utilization of nitrile rubber as sealing materials effectively prevented the water leakage and corrosion,and observation of relatively smooth and clear picture were conducted by setting decoding resolution option to QCIF or CIF mode,with maximum bitrate of 120 kbps and frame rate of 8-15.The findings can be used in real-time observation of underwater cultured organisms and environment monitoring in sea ranching areas.
