The combination of highly equipped smartphones, with the increased use of social media, has offered a wide database. Given this, citizen science can be used to record and monitor non-native fish fauna, target new samples and collaborate with monitoring occurrences in new areas. We aimed to demonstrate the efficiency of social media in citizen science as a tool to cooperate with monitoring studies of non-native species. Consequently, we determined the occurrence points of S. brasiliensis in the Iguaçu River basin, indicating sites of greatest occurrence and analyzing the impact of the invasion on the native fauna of the basin. Files and information available on the YouTube^® and Facebook^® media platforms were used as data, was carried out from April 2019 to April 2020. The results were 40 records, 22 videos obtained from Youtube, and seven videos and 11 photos from Facebook, the oldest record was from April 2013, while the largest number of posts was in 2016. Fish records available from online platforms can reveal the occurrence and progressive dispersion of species, in the context of biological invasions, these tools can be of great value in studies that aim to follow the progress of introduced species, contributing by helping to direct new sampling programs and corroborating the occurrence of species in new areas in conjunction with standard monitoring programs. Based on citizen science records, it was possible to update the range of occurrence of the non-native S. brasiliensis in the Iguaçu River basin, cooperating with scientific knowledge. Innovative monitoring and control measures are necessary to deal with invasive species, with citizen science proving to be competent for determining the occurrence of species and showing promise in the entire field of ichthyology.

新的保护机会：利用公民科学监测新热带地区的非本地物种

装备精良的智能手机与社交媒体使用的增加相结合，提供了广泛的数据库。鉴于此，公民科学可用于记录和监测非本地鱼类群、瞄准新样本并与监测新地区的事件合作。我们旨在证明社交媒体在公民科学中的效率，作为与非本地物种监测研究合作的工具。因此，我们确定了伊瓜苏河流域 S. brasiliensis 的发生点，指出了发生最多的地点，并分析了入侵对流域本土动物群的影响。YouTube ^®和 Facebook ^®上提供的文件和信息以媒体平台为数据，从2019年4月到2020年4月进行，结果是40条记录，22个视频来自Youtube，7个视频和11张照片来自Facebook，最早的记录是2013年4月，而最多的帖子的数量是 2016 年。在线平台提供的鱼类记录可以揭示物种的发生和逐渐分散，在生物入侵的背景下，这些工具在旨在跟踪引进物种进展的研究中具有重要价值，有助于帮助指导新的采样计划，并结合标准监测计划证实新地区物种的出现。根据公民科学记录，可以更新伊瓜苏河流域的非本地巴西海螺的发生范围，与科学知识合作。应对入侵物种需要创新的监测和控制措施，事实证明，公民科学有能力确定物种的发生并在整个鱼类学领域显示出前景。
