Estimation of Fishing Vessel Numbers Close to the Terminator in the Pacific Northwest Using OLS/DMSP Data

Squid (Ommastrephes bartramii) is a kind of economic fishery resources. Artificial light at night attracts and aggregates fish and squid because it mimics light produced by bioluminescent marine animals. The fish men use lamps to aggregate squid for squid jigging. So the squid fishing vessels can be detected by the sensor of Operational Linescan System (OLS) on Defense Meteorological Satellite Program (DMSP). This article mainly used OLS shimmer data from DMSP-F18 satellite covering the Pacific northwest ocean and estimated the quantity of squid jigging fishing vessels close to the terminator to expound the method that people can utilize the night-time satellite remote sensing data to estimate the quantity of light-trapping fishing vessels.
