ABSTRACT
The indigenous or local knowledge acquired over the time by the community/individuals in this particular ecosystem plays an important role in detection and catching of any specific fish abundance in any specific part of rivers and estuaries around the world. The Hilsa supports an estimated 0.45 million full-time and 2.5 million part-time fishers. The project, ‘Investing in Hilsa fishery as an Economic Infrastructure for Bangladesh’ encompassed activities designed to address key areas of work such as improved science based fisheries management decision making, strengthened fisheries adaptive co-management, and enhanced socio-ecological resilience of target communities. Remotely sensed imageries data of both active and passive were used in this study to monitor the Hilsa habitat in the south-central to southwest coastal area of Bangladesh. A radar system operates in a specific wavelength or frequency and records the signal response from the ground or target at single specific wavelength.
