摘要： Performing statistical computations for traditional fishing effort takes much time and effort, and the macro fishing effort cannot be accessed immediately. Through the Beidou satellite vessel position monitoring system, the position, time, speed and other information of vessels can be got and used to data mining. In this paper, the speed threshold of each vessel's fishing state is obtained by the statistics of navigational speed. And fishing state points can be judged by the speed threshold and heading deviation. Via the correction of filtering window, the fishing area grid is calculated by the cumulative fishing time. The cumulative fishing is the product of the cumulative fishing time and the vessel power, such as kW.h. This method has the characteristics of real-time, large-scale, fast and high resolution, which can provide good service in fishery resources protection.
