Summary There are a number of areas in Asia where heavily-lit fishing boats are detected There are a number of areas in Asia where heavily-lit fishing boats are detected NGDC has a fifteen year time series which shows that the fishing boat activity is highly dynamic spatially and temporally NGDC has a fifteen year time series which shows that the fishing boat activity is highly dynamic spatially and temporally The detected lights have not yet been intersected with aquaculture The detected lights have not yet been intersected with aquaculture The use of near real time OLS data in fisheries management is being explored by Japan and Korea.
