The impact of non-native species, together with their pervasiveness, necessitates a means of identifying which species are most likely to pose an elevated risk of becoming invasive. This is amongst the first applications of the Aquatic Species Invasiveness Screening Kit (AS-ISK) decision support tool in Southeast Asia, and specifically for Vietnam. In total, 30 extant and horizon non-native aquatic species were screened for their potential invasiveness in Vietnam. A threshold score of 6.75 was identified for distinguishing between species likely to pose a high and low-to-medium risk of becoming invasive in Vietnam for both the basic risk assessment (BRA) and the climate change assessment (BRA + CCA) components of the screening process. However, the absence of nationally-consistent predictions on climate change impacts in Vietnam restricted the applicability of the climate change assessment component. Based on the BRA threshold, of the 30 species screened, 25 were classified as high risk, four as medium risk, and one as low risk. For the BRA, the highest-scoring species were Hypostomus plecostomus, Pomacea canaliculata and Lithobates catesbeianus. This study reliably identified and discriminated between non-invasive and potentially invasive aquatic species in Vietnam, thereby providing appropriate AS-ISK score thresholds with which to guide policy and decision-making. This suggests that the AS-ISK could be successfully employed to screen non-native aquatic species in other parts of Southeast Asia.

非本地物种的影响及其普遍性，需要一种手段来确定哪些物种最有可能带来更高的入侵风险。这是东南亚尤其是越南的水生生物入侵筛选工具包（AS-ISK）决策支持工具的首次应用。总共筛选了30种现存和地平线外来水生物种在越南的潜在入侵性。在越南的基本风险评估（BRA）和气候变化评估（BRA + CCA）组成部分中，确定阈值得分为6.75，以区分可能在越南造成入侵的高风险和中低风险的物种。筛选进程。然而，越南对气候变化影响缺乏全国一致的预测，限制了气候变化评估部分的适用性。根据BRA阈值，在筛选的30个物种中，有25个被归类为高风险，四个被归类为中等风险，一个被归为低风险。对于BRA，得分最高的物种是斜纹夜蛾（Hypostomus plecostomus），波马贝（Pomacea canaliculata）和牛肝石 这项研究可靠地确定和区分了越南的非侵入性和潜在侵入性水生物种，从而提供了适当的AS-ISK分数阈值，可用来指导政策和决策。这表明AS-ISK可以成功地用于筛选东南亚其他地区的非本地水生物种。
