Application of Thermal Remote Sensing in Fish Harvesting
Introduction : Using satellites in fish harvesting is due to the great advantages they provide such as the wide range capture of see surface “large coverage”, temporal resolution and data are independent from weather. So that remote sensing has real impact on uncovering the relationship between fish distribution and surrounding environment. The main objective of using remote sensing is to reduce search time and increase catch rate. There are two methods to apply remote sensing data: Indirect Method: measuring oceanographic and environmental factors that correlate with fish habitat, such as ocean colour, sea surface temperature (SST), wind stress, current data, and other environmental characteristic that affect fish habitat Also, known the fact that fish correlate with nutrient-rich waters. Direct method: by spotting fish appearance. Measuring the environmental factors is much easier than spotting the appearance of a fish. And the main source for fisheries management is thermal inf
