Abstract

Ethiopia is branded as the Water Tower of Africa because of its abundant inland water bodies that may be used sustainably to boost the economy. This review article’s goal is to examine the current status and future potential of Ethiopia’s fisheries, with a special focus on reservoirs. There are 200 known fish species (194 native, 40 endemic, and 11 exotic) in in Ethiopia’s inland water. Ethiopia’s fish production has increased by a factor of more than five in the past three decades (3,500 tons in 1983 to 15,681 tons in 2000 and 18,058 tons in 2010). However, fish produced in reservoirs is too low (8,059 t/year). The current fish harvests from reservoirs are significantly below the predicted potential yield, accounting for only 35% of the calculated fish production capacity. In this review, 14 potential reserves were revealed. A total of 48 fish species have been reported in these, of which 26 species (or around 54%) are present in Alwero reservoir. 19 of the 48 species that have been officially recognized belong to the Cyprinidae family and made up nearly 40% of the fish population in Ethiopian reservoirs. There has been, however, a decline in the productivity of Ethiopia’s reservoir fish. Hence, actively start fishing in the numerous reservoirs that have been neglected yet, link the potential of fisheries and the benefits of the fish farming supply chain, let’s begin building several other reservoirs similar to the Grand Ethiopian Renaissance Dam and beginning mechanized-based fish harvesting.

埃塞俄比亚水库的渔业现状:挑战和管理
埃塞俄比亚被称为非洲水塔,因为其丰富的内陆水体可以可持续地用于促进经济发展。这篇综述文章的目的是研究埃塞俄比亚渔业的现状和未来潜力,特别关注水库。埃塞俄比亚内陆水域有200种已知的鱼类(194种本地鱼类,40种地方性鱼类和11种外来鱼类)。埃塞俄比亚的鱼类产量在过去三十年中增加了五倍多(1983年为3500吨,2000年为15681吨,2010年为18058吨)。然而,水库的鱼产量太低(8059吨/年)。目前水库的鱼类产量明显低于预测的潜在产量,仅占计算鱼类生产能力的35%。本次评价共发现14处潜在储层。共发现48种鱼类,其中26种(约占54%)存在于Alwero水库。在已被正式确认的48种鱼类中,有19种属于鲤科,占埃塞俄比亚水库鱼类种群的近40%。然而,埃塞俄比亚水库鱼类的产量有所下降。因此,积极开始在众多尚未被忽视的水库中捕鱼,将渔业的潜力与鱼类养殖供应链的利益联系起来,让我们开始建造其他几个类似于埃塞俄比亚复兴大坝的水库,并开始机械化捕鱼。
