Hilsa shad is the largest single fish species, contributing 12% of the total fish production in Bangladesh. Since the rapid decline of its harvest in early 2000, the government of Bangladesh took various initiatives to accelerate the hilsa production and introduced the hilsa fisheries management action plan in 2005. Under WorldFish led enhanced coastal fisheries project, implemented in partnership with the Department of Fisheries, the hilsa fishery reversed and experienced record harvest in 2016. Therefore, this study was undertaken to explore the contributions and benefits of this increased hilsa shad production among value chain actors. The results revealed that increased catches have significant impacts on the volumes of hilsa that were handled by the value chain actors, which depressed market price along the value chain. However, the increased amounts of hilsa harvested compensated for the reduced price and led to increased profits, increased household incomes of the value chain actors, and enhanced fish consumption at the household levels. The increased hilsa catch also had positive and significant impacts on credit repayment. Therefore, the incentive-based co-management system deserves continuation to improve the livelihood of the poor hilsa fishers, to increase the income of the value chain actors and to ensure a sustainable hilsa fishery for Bangladesh.

孟加拉国hilsa shad（Tenualosa ilisha）收成增加的价值链影响

希尔萨sha鱼是最大的单一鱼类，占孟加拉国鱼类总产量的12％。自从2000年初产量急剧下降以来，孟加拉国政府采取了各种行动来加快hilsa的生产，并于2005年推出了hilsa渔业管理行动计划。在世界渔业组织的领导下，与渔业部合作实施了加强沿海渔业项目，希尔萨（Helsa）渔业在2016年逆转并取得了创纪录的收成。因此，本研究旨在探索价值链参与者中这种希尔萨sha鱼产量增加的贡献和益处。结果表明，捕获量的增加对价值链参与者处理的hilsa的数量产生了重大影响，从而降低了价值链上的市场价格。然而，收获的希尔沙数量增加弥补了价格下跌的影响，并导致利润增加，价值链参与者的家庭收入增加以及家庭一级的鱼类消费增加。hilsa捕获量的增加也对信贷还款产生了积极而重大的影响。因此，基于激励的共同管理制度应继续下去，以改善贫穷的希尔萨渔民的生计，增加价值链参与者的收入，并确保孟加拉国可持续的希尔萨渔业。
