本研究旨在调查南非北方夸祖鲁-纳塔尔的Phongolo河下游洪泛区个体渔业的现状。横断面定量调查的设计，包括开发的问卷和系统的调查之间的五个村庄接壤的Ndumo禁猎区。由16名实地工作人员组成的小组在5天内收集数据，并使用社会科学统计软件包第21版进行分析。结果显示，鱼是该地区第三大消耗蛋白质，人们平均每周吃两次鱼，至少有六种鱼类（和一种最近引进的小龙虾）经常食用，大多数鱼是从当地供应商那里获得的，他们又从当地渔民和妇女那里购买。捕鱼活动似乎也主要发生在沿着水系，主要以红胸罗非鱼为目标（罗非鱼rendalli）和莫桑比克罗非鱼（Oreochromis mossambicus）和非洲尖齿鲶鱼（在较小程度上）（革胡子鲶）和棕色吱吱（Synodontis zambezensis）。鉴于Ndumo居民主要以非商业性方式捕鱼，他们这样做是为了个人消费和维持生计，而且它们主要针对河流和水坝，而不是该地区生态敏感的水域，因此该地区的渔业目前似乎可能是可持续的。不过，我们建议就本地鱼类种群及其繁殖率进行研究，以便更准确地确定对本地鱼类种群的实际影响。这项研究提供了该地区鱼类利用的必要基线数据，一旦完成种群研究，就可以确定个体捕捞对恩杜莫地区鱼类保护区的影响。
The aim of this study was to investigate the status of artisanal fisheries in the lower Phongolo River floodplain in northern KwaZulu-Natal, South Africa. A cross-sectional quantitative survey design was used that included the development of a questionnaire and a systematic survey among the five villages bordering the Ndumo Game Reserve. Data were collected over a 5-day period by a group of 16 fieldworkers and analysed using the Statistical Package for the Social Sciences, version 21. The results revealed that fish was the third most consumed protein in the area, that people consumed fish on average twice a week, that at least six fish species (and one recently introduced crayfish species) were consumed regularly, and that most fish were obtained from local vendors, who in turn bought it from local fishermen and -women. Fishing activities also appeared to occur predominantly along the river system and targeted mainly red-breasted tilapia (Tilapia rendalli) and Mozambique tilapia (Oreochromis mossambicus) and, to a slightly lesser extent, African sharptooth catfish (Clarias gariepinus) and brown squeaker (Synodontis zambezensis).Conservation implications: Given that Ndumo residents predominantly catch fish by means of non-commercial methods, that they do so for reasons of personal consumption and subsistence, and that they mostly target rivers and dams rather than the ecologically sensitive pans in the region, it would seem likely that fishing in the region might be sustainable for the moment. However, it is recommended that studies on the local fish populations and their reproductive rates be conducted so that the actual impact on local fish populations can be determined more accurately. This study serves to provide the necessary baseline data on fish utilisation in the region, which would enable the impact of artisanal fishing on fish reserves in the Ndumo region to be determined once population studies have been completed.
