Abstract

The study aims to quantify the volumes of small pelagic fish harvested and supplied to processing industries for fishmeal and fish oil production. Structured surveys and targeted interviews were conducted with key industry stakeholders in the Dakar, Thiès, and Saint-Louis regions. These methods facilitated an assessment of the proportion of catches allocated to industrial processing and an analysis of the repercussions of this practice on fish stock sustainability and food security. The findings reveal an average annual fishmeal production of approximately 13,000 tons in 2023, while fish oil production showed greater variability, reaching a peak of 3870 tons in the same year. Furthermore, the distribution of artisanal fishing units contracted by processing industries varies by site. In total, 17 artisanal fishing units were reported under contract, including 16 purse-seine units and one (01) encircling gillnet unit. Notably, the coefficients of variation between industry-reported data and those from fishers and fishmongers were 0.96 and 0.72, respectively, indicating significant discrepancies among stakeholders. The study underscores the urgent need for regulatory measures in the fish processing sector to balance between industrial and national food needs. Promoting product traceability and sustainable fisheries management are critical strategies for mitigating the industry's impact on local consumption and ensuring the long-term viability of small-scale fishing activities.

在塞内加尔加工成鱼粉和鱼油的鱼类产品的定量

这项研究的目的是量化捕捞并供应给加工工业生产鱼粉和鱼油的小型远洋鱼类的数量。对达喀尔、thi和圣路易斯地区的主要行业利益相关者进行了结构化调查和有针对性的访谈。这些方法有助于评估分配给工业加工的渔获量的比例，并分析这种做法对鱼类可持续性和粮食安全的影响。研究结果显示，到2023年，平均每年的鱼粉产量约为1.3万吨，而鱼油产量则表现出更大的变化，在同一年达到3870吨的峰值。此外，加工工业承包的手工捕鱼单位的分布因地点而异。据报共有17个承包的手工捕鱼单位，包括16个围网单位和1个围网单位。值得注意的是，行业报告数据与渔民和鱼贩数据之间的变异系数分别为0.96和0.72，表明利益相关者之间存在显著差异。这项研究强调迫切需要在鱼类加工部门采取管制措施，以平衡工业和国家粮食需求。促进产品可追溯性和可持续渔业管理是减轻渔业对当地消费的影响和确保小规模渔业活动长期生存的关键战略。

期刊介绍： Marine Policy is the leading journal of ocean policy studies. It offers researchers, analysts and policy makers a unique combination of analyses in the principal social science disciplines relevant to the formulation of marine policy. Major articles are contributed by specialists in marine affairs, including marine economists and marine resource managers, political scientists, marine scientists, international lawyers, geographers and anthropologists. Drawing on their expertise and research, the journal covers: international, regional and national marine policies; institutional arrangements for the management and regulation of marine activities, including fisheries and shipping; conflict resolution; marine pollution and environment; conservation and use of marine resources. Regular features of Marine Policy include research reports, conference reports and reports on current developments to keep readers up-to-date with the latest developments and research in ocean affairs.
