The capture and culture marine fisheries play a far-reaching role in the food security, poverty alleviation and economy of Bangladesh. Marine fisheries resources from the Bay of Bengal have been overexploited resulting in the development of coastal aquaculture to fulfil the protein demand, employment of the excess population and export earnings. Inevitably, the demand for low-value fish has supported the increased fishing pressure on overexploited resources in many countries. Bangladesh marine capture fishery is dominated by small-scale, labour-intensive artisanal vessel practices where multiple gears are used to catch mainly target species. The poorest of the poor fisher folks and the marginal fisher communities are extremely dependent on fishing for their livelihood. This survival pressure drives overexploitation and ecosystem deterioration. The lack of adequate management measures, poor implementation of policy tools and conflicting short-term production growth adopted by the national authorities are challenging for the sustainable fisheries development in the coastal belt.
