  • 摘要:Pacific saury, Cololabis saira, a commercially important species for multi-national fishing fleets in northwestern Pacific is fished using bright lights to attract schools. The lights are easily monitored using night-time visible images from Defence Meteorological Satellite Program/Operational Linescan System (DMSP/OLS). Modeling the relationship between fishing light distribution and numbers of fishing vessels can facilitate near-real time prediction and management of saury fisheries. The objective of this study was to estimate the numbers of fishing vessels from night-time images and landing data in northwestern Pacific coast. Analysis was conducted in ArcGIS. Results show that spatial fishing light distribution is significantly related to numbers of fishing vessels. For instance, in September from 2003 to 2006, the number of emitted pixels was significantly correlated to number of fishing vessels. We suggest that it is possible to estimate fishing effort from remotely sensed night-time visible images
