Focusing on extreme climatic events in India’s Western Ghats Biodiversity Hotspot, we demonstrate that unmanaged aquaculture and unregulated fisheries can often combine with ECE in exacerbating biological invasions through the unexpected introduction and escape of novel alien species. High magnitude flooding events in August 2018 and 2019 resulted in the escape of at least ten alien fish species that were recorded for the first time, from the natural waters of the Western Ghats. Illegal farming systems, aqua-tourism destinations and amusement parks, as well as reservoirs, facilitated the escape of alien species during the ECE. Despite expanding invasions, unmanaged stocking and aquaculture using alien species continue in the Western Ghats, necessitating urgent management and policy interventions.

着眼于印度西部高止山脉生物多样性热点的极端气候事件，我们证明了未经管理的水产养殖和不受管制的渔业通常可以与欧洲经委会结合，通过意外引入和逃逸新的外来物种加剧生物入侵。2018年8月和2019年8月的高洪灾事件导致至少有十种外来鱼类物种从西高止山脉的天然水域中逃逸，这是首次被记录下来。非法的耕作制度，水上旅游目的地和游乐园以及水库在欧洲经委会期间为外来物种的逃逸提供了便利。尽管入侵不断扩大，西高止山脉仍在继续使用外来物种进行无管理的放养和水产养殖，因此需要紧急的管理和政策干预措施。
