Black bass Micropterus spp. are highly sought‐after sport fish and, where introduced, are emblematic of the tradeoffs between ensuring productive fisheries and conserving native biodiversity. To disentangle these potentially conflicting interests, we administered a survey of fisheries biologists in the United States to assess perceptions regarding ecological and economic impacts of non‐native black bass between anthropogenic and natural habitats. Our results indicate that non‐native black bass are generally considered economically beneficial in both habitat types. Contrastingly, these species were perceived to have significantly more negative ecological impacts in natural than anthropogenic habitats. Our findings suggest that habitat may be an important factor to partition the conflicting ecological–economic dynamic of non‐native black bass. Implications of this study suggest that challenges remain for managers attempting to balance the paradoxical nature of these species as both desired sport fishes and as potentially harmful invaders when found outside their native range.

美国非本土黑鲈的可感知生态威胁和经济利益

黑鲈Micropterusspp。是备受追捧的运动鱼，并且在引入时是确保生产性渔业与保护本地生物多样性之间权衡的象征。为了弄清这些潜在的利益冲突，我们在美国进行了一项渔业生物学家调查，以评估对人为和自然栖息地之间非本地黑鲈的生态和经济影响的看法。我们的结果表明，在两种生境类型中，非本地黑鲈通常被认为具有经济效益。相反，人们认为这些物种在自然方面比人为栖息地具有更大的负面生态影响。我们的发现表明，栖息地可能是划分非本地黑鲈冲突生态和经济动态的重要因素。
