This study investigated the perceptions on and adaptations to climate change impacts of 235 pangasius farmers in the Mekong Delta, Vietnam. Data were collected using semi-structured household surveys in six provinces, from three regions along the Mekong river branches. A Chi-Square test was used to determine the association between variables, and a logit regression model was employed to identify factors correlated with farmer's perception and adaptation. Less than half of respondents were concerned about climate change and sought suitable adaptation measures to alleviate its impacts. Improving information on climate change and introducing early warning systems could improve the adaptive capacity of pangasius farmers, in particularly for those farmers, who were not concerned yet. Farmers relied strongly on technical support from government agencies, but farmers in the coastal provinces did not express the need for training by these institutions. This contrasting result requires further assessment of the effectiveness of adaptation measures such as breeding salinity tolerant pangasius.
本研究调查了越南湄公河三角洲235名鲶鱼养殖户对气候变化影响的认知及适应情况。研究数据通过对湄公河各支流沿线三个地区六个省份的养殖户进行半结构化家庭调查收集。采用卡方检验确定变量之间的关联，并运用逻辑回归模型识别与养殖户认知及适应相关的因素。不到一半的受访者担心气候变化，并寻求合适的适应措施以减轻其影响。改善气候变化信息并引入预警系统可以提高鲶鱼养殖户的适应能力，特别是对于那些尚未关注气候变化的养殖户。养殖户强烈依赖政府机构的技术支持，但沿海省份的养殖户并未表示需要这些机构提供培训。这一对比结果需要进一步评估诸如培育耐盐鲶鱼等适应措施的有效性。
