1. This article highlights the practical impact of our 2018 Aquatic Conservation: Marine and Freshwater Ecosystems publication, ‘Importance of peripheral basins: Implications for the conservation of fish assemblages’, which described fish communities in a Polish river.
2. Data on the fish assemblages of the Dniester River (Black Sea basin) are scarce; however, evidence indicates that the assemblages have declined. In our 2018 study, we hypothesized that the peripheral basin (the small basin on the edge) of the larger Upper Dniester River basin (the Strwiąż River) could maintain good ecological status and contained unique fish assemblages.
3. To examine the influence of historical factors and assess the role of peripheral basins on fish conservation, data from the Strwiąż basin were compared with the adjacent but unconnected Wiar basin (the Vistula basin; Baltic Sea basin). The Strwiąż River fish assemblages featured higher species richness and a greater number of native Ponto–Caspian species that function near the edge of their ranges.
4. This article focuses on four impacts of the 2018 publication: increasing awareness by various groups and organizations of the unique character of the surveyed river basin; highlighting important issues in assessing the ecological status of European rivers; driving the red‐listing of species and the development of stream fish conservation strategies; and identifying possible future impacts.
5. Our 2018 publication demonstrated the value of studying peripheral basins, which may affect conservation strategy development and encourage study of the importance of other peripheral basins and their role in aquatic resources conservation. Our article influenced the interpretation of fish‐based biotic indices and the conduct of monitoring work and its evaluation. It also strongly emphasized the native origin of the racer goby (Babka gymnotrachelus) in the Strwiąż River, which was important for subsequent works seeking to change the legal status of the species in Poland.

保护鱼类群落：通过取得实际效果延长“研究生命周期”

1. 本文重点介绍了我们2018年《水生保护：海洋和淡水生态系统》出版物的实际影响，``周边盆地的重要性：对鱼类种群保护的影响''描述了波兰河中的鱼类群落。
2. 关于德涅斯特河（黑海盆地）鱼群的数据很少；但是，有证据表明，此类活动已经减少。在我们的2018年研究中，我们假设较大的上德涅斯特河盆地（Strwiąż河）的外围盆地（边缘的小盆地）可以保持良好的生态状况并包含独特的鱼类组合。
3. 为了检查历史因素的影响并评估外围盆地对鱼类保护的作用，将Strwiąż盆地的数据与相邻但未连通的Wiar盆地（维斯瓦河盆地；波罗的海盆地）进行了比较。Strwiąż河鱼群具有较高的物种丰富度，并具有大量在其范围边缘附近起作用的蓬图–里海原生鱼类。
4. 本文着重探讨2018年出版物的四方面影响：各团体和组织提高对被调查流域独特特征的认识; 突出评估欧洲河流生态状况的重要问题；推动物种重新列入清单并发展溪流鱼类保护战略；并确定可能的未来影响。
5. 我们2018年的出版物证明了研究外围流域的价值，这可能会影响保护战略的制定，并鼓励研究其他外围流域的重要性及其在水生资源保护中的作用。我们的文章影响了鱼类生物指数的解释以及监测工作及其评估的进行。它还强烈地强调了虾虎鱼（Babka Gymnotrachelus）在Strwiąż河中的原产地，这对于随后寻求改变该物种在波兰的法律地位的工作很重要。
