1. Human translocations of non-native aquatic species are a global conservation challenge. Aquarists and anglers are two hobbyist groups whose practices are particularly likely to translocate non-native aquatic species, especially fish.
2. This article aims to stipulate a change of perspective among these hobbyists, who – by acting simultaneously as anglers and aquarists – establish novel pathways for non-native fish.
3. This study showed that: (i) 51 of 226 respondents to a questionnaire act simultaneously as anglers and aquarists; (ii) 53 of 237 non-native fish species in the European Union are used for both angling and aquarium hobbies; and (iii) hobbyists write online reports on the catch and exchange of a particularly invasive fish, the round goby (Neogobius melanostomus).
4. This combination of knowledge on how hobbyists use non-native fish and the ecological impacts of round goby demonstrates how the impact of an invasive species can be influenced by the combined behaviours of anglers and aquarists.
5. We suggest that future research in aquatic conservation should move beyond considering the commercial aquarium trade and angling as separate pathways for translocating non-native fish, and instead consider these hobbyist groups as interconnected.

业余爱好者同时充当垂钓者和水族爱好者：非本地鱼类的新途径及其对本地鱼类的影响

1. 非本地水生物种的人类易位是一项全球保护挑战。水族爱好者和垂钓者是两个业余爱好者群体，他们的做法特别有可能转移非本地水生物种，尤其是鱼类。
2. 本文旨在规定这些爱好者的观点转变，他们同时充当垂钓者和水族爱好者，为非本地鱼类建立新的途径。
3. 这项研究表明： (i) 问卷的 226 名受访者中有 51 人同时担任垂钓者和鱼友；(ii) 欧盟 237 种非本地鱼类中有 53 种用于垂钓和水族馆爱好；(iii) 业余爱好者撰写关于捕捞和交换一种特别具有入侵性的鱼，圆形虾虎鱼 ( Neogobius melanostomus ) 的在线报告。
4. 这种关于业余爱好者如何使用非本地鱼类的知识以及圆形虾虎鱼的生态影响的知识的结合展示了入侵物种的影响如何受到垂钓者和水族爱好者的综合行为的影响。
5. 我们建议未来的水生保护研究不应将商业水族馆贸易和垂钓视为迁移非本地鱼类的单独途径，而是将这些爱好者群体视为相互关联的。
