“…With enough records accumulated, these catch and effort data can be analysed to understand when and why anglers are fishing, similar to the way logbooks have historically been used in recreational fisheries (Vinson & Angradi, 2014). Digital data that specify angling gear have also been found useful to track angler movements, relating these movements to the spread of invasive species (Fricke et al, 2020; Magalhães et al, 2021) and future Internet‐of‐things connectivity may allow more passive collection about angler activity.…”

Recreational fisheries are diverse in scale, scope, and participation worldwide, constituting an important ecosystem service of marine and freshwater ecosystems.Management of these socio-ecological systems is challenged by monitoring gaps, stemming from difficulties engaging with participants, biased sampling, and insufficient resources to conduct biological or social surveys of fish and human populations.In the Internet age, online data have great potential to make a meaningful contribution to recreational fisheries research, monitoring, and management. Recreational fishers in some countries increasingly use social and other digital media to share their experiences with followers, with most data freely available to web scrapers that compile databases of text (e.g. tweets, status updates, comments), photos, videos and other media that contain information about spatiotemporal activity, sentiments towards catches/experiences, targeted and bycatch species, effort levels, and more.Although the future of recreational fisheries research, monitoring and management will likely involve more digital scraping, uptake is only just beginning and there are

“…Portanto, os estudos sobre impactos de espécies não-nativas e padrões de diversidade em maiores escalas espaço-temporais (e.g., homogeneização/diferenciação bióticas) também devem ser incentivados (Magalhães et al 2020a), pois fornecem informações que devem ser consideradas em medidas de manejo (Figura 4). Igualmente importante é a pesquisa sobre iEcologia (i.e., Ecologia da Internet, Ferraz et al 2019, Jarić et al 2020, Magalhães et al 2021 através de redes sociais como o YouTube ® , pois permite: i) identificar novas espécies de peixes não-nativos introduzidos em riachos em vários locais do Brasil; ii) detectar novos pontos 2019) sobre a ética do uso das redes sociais na pesquisa ictiológica, e deixamos anônimos todos os dados pessoais dos donos dos quatro canais (identificação dos links dos vídeos, identificação dos vídeos/ canais, título dos vídeos/canais, duração dos vídeos).

“…Paralelamente, órgãos ambientais como o IBAMA e Secretarias de Meio Ambiente dos estados devem aperfeiçoar sistemas de monitoramento e fiscalização, de modo a coibir novas introduções e detectar invasões ainda nas etapas iniciais, quando ações de erradicação são mais efetivas. Um interessante sistema de monitoramento e fiscalização que esses órgãos ambientais podem adotar é o YouTube ® , pois esta rede social permite identificar espécies de peixes não-nativos, chegar até os infratores (i.e., pessoas que estão liberando peixes nãonativos) via canais pessoais e rastrear a dinâmica das fases das invasões biológicas em tempo quase real (Ferraz et al 2019, Magalhães et al 2021.…”

Biological invasions are among the main causes of biodiversity loss on planet. Losses are accentuated in streams, which are sensitive to human impacts, since they have specialized fauna and higher degree of endemism. Despite this, studies on invasions by non-native fish in streams are incipient in Brazil. In this review, we present an introduction on the process (i.e., stages) of biological invasion, the environmental factors that influence the establishment and the impacts of non-native species in streams. A methodological step-by-step is also presented as a way to guide the conduct of studies on non-native species in Brazilian streams. In addition, management actions measures are presented to prevent new cases of introductions and suggestions for studies on invasions in streams. Avoiding propagule pressure and environmental education, as well as legal aspects of Brazilian legislation, are management actions that can prevent new introductions. Finally, gaps in knowledge and perspectives are raised as an incentive for interested parties to enter the subject and develop new studies on non-native fishes in Brazilian streams.

“…Nowadays, citizen science projects use several tools to connect the scientific community and society; these projects involve local communities and large populations (Rüfenacht et al ., 2021). Social media, such as YouTube, are tools used in citizen science, which bring the scientific community closer to society, allowing the development of many citizen science projects (Magalhães et al ., 2017; Magalhães et al ., 2020). Several projects showed how citizen science can substantially contribute to biodiversity monitoring in terrestrial and aquatic environments (Freitas et al ., 2020; Gibson et al ., 2019; Vendetti et al ., 2018), e.g ., bird migrations (Degroote et al ., 2021) and plant dispersion (Gallo & Waitt, 2011).…”

Citizen science is an excellent tool in studies of the spatial distribution of non‐native species. In Brazil, Opsanus beta has recently been introduced. Studies indicate the occurrence of this species in five estuaries off the Brazilian coast (Guanabara Bay, Sepetiba Bay, Santos Bay, Paranaguá Estuarine Complex and Guaratuba Bay). The present study aims to understand the dispersion of this species on the Brazilian coast through citizen science. Between January and May 2021, information about O. beta was weekly posted in 32 recreational fishing Facebook groups. Sixty‐five fishers reported catches of O. beta in estuaries (Guanabara Bay, Sepetiba Bay, Santos Bay and Paranaguá Estuarine Complex). In addition, there were reports from other shallow areas outside adjacent estuaries (Bertioga and Peruíbe, in Sao Paulo State) and the first occurrence record for Laguna (Santa Catarina State), a southern estuarine zone (28° 29′ 45″ S to 48° 45′ 36″ W). In four estuaries along the Brazilian coast where O. beta was recorded, there are internal ports that trade with countries from the Gulf of Mexico and Caribbean Sea (species original range), indicating ballast water as a possible introduction route. In Laguna, the introduction may have occurred by maritime cabotage services. The reproductive capacity, the aquarists' interest, the absence of introduction policies aimed at this species and the cabotage fleet transportation may be factors that help further extend the dispersal of O. beta on the Brazilian coast.
