Biological invasions are a major driver of global environmental change as invasive non‐native species can exert severe environmental impacts on invaded ecosystems. Estuaries are especially vulnerable to biological invasions, which in highly urbanised areas are further facilitated by introduction pathways linked to commercial activities. This study provides a risk screening of non‐native invasive species for the highly urbanised River Neretva Estuary (Eastern Adriatic Sea: Croatia and Bosnia–Herzegovina). In total, 12 species of non‐native aquatic organisms were identified and screened for their invasiveness with the Aquatic Species Invasiveness Screening Kit. Of these species, eight were classified as carrying a high risk of invasiveness under current climate conditions and nine under future climate conditions. Amongst the high‐risk species, blue crab Callinectes sapidus has already caused impacts in the risk assessment area, where it also represents an important economic resource. The “horizon” species Pacific oyster Crassostrea gigas and Manila clam Ruditapes philippinarum also carried a high risk of invasiveness, which for the latter species applied under predicted global warming. The present findings will contribute towards preventative management and control measures for the conservation of the natural ecosystem of the River Neretva Estuary whilst accounting for aquatic farming demands.

量化高度都市化的河口生态系统中非本地水生物种入侵的当前和未来风险-以内雷特瓦河河口为例（东亚得里亚海：克罗地亚和波斯尼亚和黑塞哥维那）

生物入侵是全球环境变化的主要驱动力，因为非本地入侵物种会对入侵的生态系统造成严重的环境影响。河口特别容易受到生物入侵的影响，在高度城市化的地区，与商业活动有关的引入途径进一步促进了生物入侵。这项研究为高度城市化的涅雷特瓦河河口（东亚得里亚海：克罗地亚和波斯尼亚－黑塞哥维那）提供了非本土入侵物种的风险筛选。总共鉴定出了12种非本地水生生物，并使用水生物种入侵筛选工具包对其入侵性进行了筛选。在这些物种中，有8种被归类为在当前气候条件下具有较高的入侵风险，而有9种在未来气候条件下具有较高的入侵风险。在高危物种中，saCallinectes sapidus已经在风险评估领域造成了影响，该地区也代表着重要的经济资源。“地平线”物种太平洋牡蛎Crassostrea gigas和马尼拉蛤菲律宾蛤（Ruditapes philippinarum）也具有很高的入侵风险，对于后者，这些物种在预计的全球变暖条件下应用。本研究结果将有助于在保护水产养殖需求的同时，为保护涅雷特瓦河河口自然生态系统采取预防性管理措施。
