摘要

这项基线调查旨在:(Amare, A等人,2014)评估Tekeze渔业在改善渔民生计方面的作用;(Andersson J. et al . 1998)评估家庭和个人对渔业的参与及其使用的投入;(Asmare, E., 2015)建议可持续利用Tekeze渔业资源的干预手段。2017年9月至10月,通过编制结构化问卷和清单收集数据。此外,采用目的抽样和随机抽样相结合的方法,对302户抽样家庭进行数据收集。最后,对收集到的数据进行描述性统计和推理统计分析。在研究地区,捕鱼是仅次于农作物生产的家庭直接现金收入的主要来源。因此,50.33%的受访者从事兼职工作,其余的32.78%和16.89%分别从事全职和季节性捕鱼工作。在研究区域捕鱼采用单丝和多丝刺网、鱼钩、鱼钩和鱼线。此外,渔船,其中主要使用的是钢船和木板船。大部分渔民从10月开始到5月积极参与捕鱼,有些渔民甚至参与到6月。各区域之间在渔业投入物所有权方面也观察到非常显著的差异(t = 12.5)。尽管在不同区域和地区之间观察到捕鱼的年总收益有很大差异(t = 8.8),但捕鱼对包括兼职季节性渔民和作物生产者在内的渔民(平均每年80941.46 ETB)起着相当重要的作用。另一方面,研究区域的捕鱼是高度性别偏见的活动,这使得妇女的参与可以忽略不计。然而,破坏性的捕鱼方式是使用4cm拉伸网大小的单丝刺网;资源公平问题;基础设施较差,例如;路;市场竞争问题是特克泽渔业面临的主要问题。

Baseline Survey on the Fisheries of Tekeze Reservoir, Ethiopia
This baseline survey was aimed to: (Amare, A et al, 2014) assess the role of fisheries of Tekeze in improving fisher’s livelihood; (Andersson J., et al 1998) assess household and individual involvement in fisheries and their inputs used; (Asmare, E., 2015) recommend means of interventions for sustainable use of the fishery resource of Tekeze. Data was collected from September to October 2017 by preparing structured questionnaire and checklists. In addition, mixtures of purposive and random sampling methods were employed to collect the data from 302 sampled households. Finally, the collected data were analyzed by using both descriptive and inferential statistics. Fishing in the study area is the main source of immediate cash income for the household next to crop production. Because of this, 50.33% of the respondents involve in a part time basis and the remaining 32.78% and 16.89% involves in a full time and seasonal basis of fishing respectively. Fishing in the study area is practiced by using both monofilament and multifilament gill nets, hooks, and hook and lines. In addition, the fishing boat, which mostly used are steel boat and planked boat. Mostly, fishers actively participate in fishing starting from October to May and some fishers involves even up to June. A highly significant difference in fishing input ownership were also observed between zones (t = 12.5). Even though highly significant difference in total annual gain from fishing is observed between zones and regions (t = 8.8), fishing plays a considerably important role for fishers (80941.46 ETB per a year on average) including part-time seasonal fishers and crop producer. On the other hand, fishing in the study area is highly gender-biased activity, which makes women’s participation negligible. However, destructive way of fishing by using 4cm stretched mesh sized monofilament gillnets; resource equity problem; poor infrastructure such as; road; and market competition problem are among the main problems in Tekeze fishery.
