Group-Based Mud Crab (Scylla serrata) Culture and Fattening for Sustainable Livelihoods of Coastal Communities of Bangladesh
Year: 2025
Type: article
Abstract: Mud crab (Scylla serrata) fattening has emerged as a promising aquaculture practice in coastal Bangladesh,offering a sustainable solution to pressing issues such as youth unemployment, underutilized coastal resources,and growing global demand for premium seafood. Despite its export potential and ecological advantages, thissector remains underexploited, particularly among educated but unemployed youth. This paper presents aconceptual model for group-based mud crab fattening that integrates biological, ecological, and socio-economic dimensions to promote entrepreneurship and inclusive livelihoods. Targeting regions such asKhulna, Satkhira, Bagerhat and Patuakhali - where brackish water conditions favor mud crab growth - themodel advocates for cooperative farming among youth groups, supported by technical training, sharedinfrastructure, and partial public or donor investment. Key features of the model include the formation ofgender-inclusive youth groups (20-25 members per union), establishment of demonstration ponds, andperiodic performance monitoring to ensure scalability. A financial simulation reveals that profitabilitybecomes sustainable from the very first cycle, following initial infrastructure investment. The approachcontributes to the national Blue Economy goals by converting job seekers into aquapreneurs and promotingsustainable resource management. It aligns with global sustainable development goals (SDGs), particularlySDG 1 (No Poverty), SDG 5 (Gender Equality), SDG 8 (Decent Work and Economic Growth), SDG 13(Climate Action), and SDG 14 (Life Below Water).The model also addresses potential risks such as climatevulnerability and access to capital by recommending strategic interventions, including microfinance supportand capacity-building programs. This framework provides a scalable, community-driven path for revitalizingcoastal livelihoods and strengthening Bangladesh’s position in the international aquaculture market.
