Abstract

Lake Kivu is experiencing unprecedented decline in production of Tanganyika Sardine (Limnothrissa miodon). This study sought to characterise the value chain of this fish species so as to chart its sustainable utilisation. The study performed in 2015 found two chains; an informal chain that takes 30% of the production and a formal chain that handles 70%. The average catch of sardine was 30 kg/day in the high production season and <15 kg/day in the low season. Two thirds of the fishers were not aware of the governing law. Fishing malpractices included fishing in prohibited sites, beach seining and fishing during moratorium period. Majority of fishers were not satisfied with the price offered in the market as costs involved in fishing was 701 Rwanda Francs/kg caught. This is despite the shift in time since the study was performed. Therefore, there is need for re-training of value chain actors, increasing lake surveillance, strengthening internal controls of the Fishers’ Cooperatives and improving information sharing and communication among value chain actors. Key words: Chain mapping, fisheries, Lake Kivu, stakeholder analysis, Tanganyika Sardine.
加强非洲大湖的渔业部门:对卢旺达基伍湖的坦噶尼喀沙丁鱼(Limnothrissa miodon, Boulenger 1906)的价值链分析
基伍湖正在经历坦噶尼喀沙丁鱼(Limnothrissa miodon)产量前所未有的下降。这项研究试图描述这种鱼类的价值链,以便绘制其可持续利用的图表。2015年进行的研究发现了两条链;一个非正式的链条占生产的30%,一个正式的链条占70%。沙丁鱼丰产季平均渔获量为30公斤/天,淡季平均渔获量<15公斤/天。三分之二的渔民不知道管辖法律。违规捕鱼行为包括在禁止捕鱼地点捕鱼、在海滩围网捕鱼和在休渔期捕鱼。大多数渔民对市场上提供的价格不满意,因为捕鱼的成本为每公斤701卢旺达法郎。尽管自研究开始以来时间发生了变化。因此,有必要对价值链行为体进行再培训,加强湖泊监测,加强渔民合作社的内部控制,改善价值链行为体之间的信息共享和沟通。关键词:链图,渔业,基伍湖,利益相关者分析,坦噶尼喀沙丁鱼
