This paper focuses on the ongoing project of China Fishery Administration System and studies the construction solution of the system including its network, application software and running modules based on the user's demands, especially, for administration and information. The system consists of fishing vessel registration, fishery law enforcement patrol vessel commanding, fishery law enforcement information services and, fishery resources and environment remote sensing service subsystems and most of them involve computer network, GPS, GIS and remote sensing techniques. All the national wide workstations and servers of these subsystems are constructed as a tree-star shaped computer network with ISDN, ADSL and PSTN communication lines. This solution is of the character of advanced techniques and deemed suitable for Chinese fishery management activities including law enforcement and vessel commanding.
