Mud crab fattening was introduced in Bangladesh as an adaptation strategy to cope with salinity intrusion in coastal areas, but there is a dearth of studies related to the extent of adoption and farm-level impacts of improved mud crab fattening practices. The present study identifies the determinants of adoption of improved practices and assesses their impact on the productivity and wellbeing of farmers. The findings indicate that the level of improved mud crab fattening practices adoption was low. The decision to adopt was significantly influenced by age, education, access to credit, and ownership status, while the extent of adoption depends on training days, the extension contact, and access to credit. The adoption of more than two improved practices significantly increases productivity and improves the wellbeing of crab farmers. Adoption analysis suggests that more research and investment are required to improve the adoption level. Due to their role in raising incomes, there is scope to boost the role of crab fattening in anti-poverty programs.

孟加拉国引入泥蟹育肥作为应对沿海地区盐度入侵的一种适应策略，但缺乏研究，涉及改良的泥蟹育肥方法的采用程度和对农场的影响。本研究确定了采用改良做法的决定因素，并评估了其对农民生产率和福祉的影响。研究结果表明，采用改进的泥蟹育肥方法的水平较低。采纳的决定在很大程度上受年龄，教育程度，获得信贷的机会和所有权状态的影响，而采纳的程度则取决于培训天数，扩展联系以及获得信贷的机会。采用两种以上的改进做法可以显着提高生产力并改善捕蟹者的福祉。收养分析表明，需要更多的研究和投资来提高收养水平。由于它们在增加收入方面的作用，因此有很大的空间可以提高螃蟹育肥在反贫困计划中的作用。
