This study assessed the factors contributing to postharvest loss of fish around the Fincha'a, Amarti, and Nashe reservoirs in Horro Guduru Wollega, Oromia, Western Ethiopia, using semi-structured questionnaires from January, 2022 GC onward. The aim of the finding was to know the fish handling and post-harvest preservation of fish around the reservoirs. In the study area, 320 respondents were selected using a random sampling system. Findings revealed that 61.1% of respondents consume fish without processing, with only 20.8% using salting and 18.1% practicing drying. The drying process notably affected texture, smell, and color. Most respondents (91.7%) preferred fresh fish due to financial constraints, lack of awareness, and market access. Species preference (40.3%), quality (33.3%), and market demand (23.6%) influenced pricing. Transportation is often done using donkey-back loads that could increase the risk of fish contamination. Although 50% of respondents stored harvested fish for one day without treatment, among these, 88.9% reported no spoilage within a day. Handling materials varied, with metal containers (33.3%) being the most common. Fish is primarily consumed as stew (39.4%) in the study area. Among these, almost all (91.9%) enjoy eating fish. However, it is often viewed as food for children and for the poor by many of them (60.6%). Despite concerns over fish bones and odors of the fish, 80.6% reported no health issues related to consumption. Most respondents (90.3%) discarded spoiled fish due to a lack of training in fish harvesting and preservation. The study indicates that postharvest losses are minimal due to effective harvesting methods, with immediate consumption practices prevalent in the community.
本研究从公元2022年1月起,通过半结构化问卷,评估了埃塞俄比亚西部奥罗米亚州霍罗古杜鲁沃莱加地区芬查阿、阿玛蒂和纳舍水库周边鱼类产后损失的影响因素。研究目的是了解水库周边鱼类的处理方式及产后保存情况。在研究区域,采用随机抽样系统选取了320名受访者。研究结果显示,61.1%的受访者不经过加工就食用鱼类,只有20.8%的人采用腌制方法,18.1%的人采用干燥方法。干燥过程对鱼的质地、气味和颜色有显著影响。由于经济限制、缺乏认知和市场准入等原因,大多数受访者(91.7%)更喜欢新鲜鱼。物种偏好(40.3%)、质量(33.3%)和市场需求(23.6%)影响着价格。运输通常采用驴驮,这可能会增加鱼类受污染的风险。尽管50%的受访者在未经处理的情况下将收获的鱼存放一天,但其中88.9%的人报告称一天内鱼没有变质。处理鱼的材料各不相同,金属容器(33.3%)最为常见。在研究区域,鱼主要作为炖菜食用(39.4%)。其中,几乎所有人(91.9%)都喜欢吃鱼。然而,许多人(60.6%)通常将其视为儿童和穷人的食物。尽管担心鱼刺和鱼的气味,但80.6%的人报告称食用鱼后没有健康问题。由于缺乏鱼类捕捞和保存方面的培训,大多数受访者(90.3%)丢弃了变质的鱼。研究表明,由于有效的捕捞方法,产后损失最小,社区中即时消费的做法很普遍。
