摘要

本山古尔-古穆兹地区州拥有丰富的自然资源;水体包括常年和间歇性河流、水库和洪泛平原,鱼类种类繁多。几个世纪以来,渔业资源主要由土著古姆兹人和贝尔塔人开发利用。 据估计,主要河流的年捕鱼总量为 2400 吨/年,阿拜河占该地区总潜力的 70%。渔获量从未被系统地记录下来,确切的数据也不得而知。不过,2006 年进行的农村家庭社会经济调查显示,在所有抽样的 150 个乡镇中,有 132 个乡镇(88%)使用河流中的鱼类。调查还显示,20 个乡中有 70%-83%、10 个乡中有 50%-70%、19 个乡中有 10%-45%的人可以到附近的河流捕鱼。 曼都拉(Mandura)和西尔巴阿巴依(Sirba Abay)县的全部人口以及毛科莫(Maokomo)、古巴(Guba)、布伦(Bulen)和凯马什(Kemashi)县 36 个乡 83% 的人口以鱼为食。目前的开发水平估计仅为 183 吨/年。捕获的鱼主要用于家庭消费,当产量超过家庭需求时,很少在市场上出售鲜鱼和/或干鱼。沿河沿海地区居民的人均鱼类消费量约为 22 公斤/人/年。鱼类对该地区的粮食安全具有特殊意义,因为捕获的所有鱼类都将由当地社区消费。

Fish Resource Survey in Benishangul-Gumuz Regional State  based on Fish Resource Survey in Benishangul-Gumuz Regional State
The Benshangul Gumuz Regional State has ample natural resources; water bodies constitute perennial and intermittent rivers, reservoirs and flood plains with diversified fish species. The fishery resource has been exploited for centuries mainly by indigenous Gumuz and Berta peoples.  The total annual harvestable fish from major Rivers is estimated to be 2400 tons/yr and River Abay covers 70% of the region’s total potential. The catch has never been recorded systematically and exact data are not known. However, the rural household based socio-economic survey conducted in 2006 indicated that from all sampled 150 Kebeles, 132 Kebeles (88%) used fish from the rivers. The survey reveals also that 70-83% of 20 Kebeles, 50-70% of 10 Kebeles and 10-45% of 19 Kebeles population have access for fishing at the nearby rivers.  The whole population of Mandura and Sirba Abay Woredas and 83% of the population in 36 Kebeles of Maokomo, Guba, Bulen and Kemashi Woredas used fish for food. The current exploitation level is estimated only at 183 tons/yr. The catches are used mostly for home consumption and rarely sold in marketing places as fresh and/or dried when the production exceeds the needs of the family. Along the river coastal areas per capita consumption of fish amongst the peoples reaches about 22 kg/person/yr. Fishes are of special significance for food security in the region, as all the fish caught is going to be consumed by local communities.
