Abstract: | Fishing and shellfish aquaculture are important sources of income for coastal communities in Thailand and other parts of tropical Asia, but environmental impacts associated with these small-scale activities can effect water quality, nearshore habitats, and fish populations. The management of coastal fisheries and aquaculture has, therefore, become a major concern for government fisheries officials who are searching for cost effective measures to improve the regulation of these sectors. Synthetic aperture radar (SAR) images from the RADARSAT-1 satellite were acquired to determine if stationary fishing and aquaculture gears within a coastal study site in the Upper Gulf of Thailand could be identified, and if automatic signature separation of gear types was possible. The use of SAR imagery for a coastal monitoring application was also evaluated and the potential of this technology to improve resource management outcomes considered. |
