“…These were mainly driven by the alien species N. melanostomus, which dominated the communities' abundance since the first year it was observed by contributing up to ~98% of the total abundance of alien fish in 2018. The dominance of N. melanostomus which can severely impact invaded ecosystems (Kipp & Ricciardi, 2012), may be linked with the demonstrated presence of Asian clam Corbicula fluminea in Rhine river (Merschel & Bau, 2015), used as its main food resource (Nagelkerke et al, 2018;Coughlan et al, 2022). Other alien fish species not belonging to the Neogobius genus were observed with less than 100 individuals throughout the entire period.…”

“…Notably, their presence has transformed nutrient cycling in the Laurentian Great Lakes (Li et al 2021) and underpinned the escalated growth of problematic macrophytes, such as in Lough Erne, Ireland (Crane et al 2020). Mass die-offs can lead to deoxygenation and acute nutrient-based toxicity, while the persistence of empty shells may detrimentally alter habitats and community composition (McDowell and Sousa 2019;Coughlan et al 2022).…”

Preventing and controlling nonnative species invasions to bend the curve of global freshwater biodiversity loss

The Emergency Recovery Plan for freshwater biodiversity recognises that addressing non-native species is one of six principal actions needed to bend the curve in freshwater biodiversity loss. This is because introduction rates of non-native species continue to accelerate globally and, where these species develop invasive populations, they can have severe impacts on freshwater biodiversity. The most effective management measure to protect freshwater biodiversity is to prevent introductions of non-native species. Should a non-native species be introduced, however, then its early detection and the implementation of rapid reaction measures can avoid it establishing and dispersing. If these measures are unsuccessful and the species becomes invasive then control and containment measures can minimise its further spread and impact. Minimizing further spread and impact includes control methods to reduce invader abundance and containment methods such as screening of invaded sites and strict biosecurity to avoid the invader dispersing to neighbouring basins. These management actions have benefitted from developments in invasion risk assessment that can prioritise species according to their invasion risk and, for species already invasive, ensure that management actions are commensurate with assessed risk. The successful management of freshwater non-native species still requires the overcoming of some implementation challenges, including non-native species often being a symptom of degraded habitats rather than the main driver of ecological change, and eradication methods often being non-species specific. Given the multiple anthropogenic stressors in freshwaters, non-native species management must work with other restoration strategies if it is to deliver the Emergency Recovery Plan for freshwater biodiversity.
