“…Thus, tNPAs are suggested to have a striking positive effect on their adjacent aquatic ecosystems by promoting diversity, increasing community heterogeneity, and potentially enhancing the ecosystem ability to resist the establishment of IAS. While recent simulations predict a positive impact of tNPAs on lowland tropical freshwater ecosystems 12 , our result is surprising because the Gatun Lake is a reservoir with a long history of human impacts and has been heavily invaded 17,18 .…”

It has been invaded by a suite of species including a variety of fish (e.g., the peacock bass Cichla ocellaris), mollusc (e.g., the redrimmed melania snail Melanoides (Thiara) tuberculata, and the South American apple snail Pomacea bridgesii), mammals (e.g., the American manatee Trichechus manatus), and macrophytes (e.g., the water thyme Hydrilla verticillata and the water hyacinth Eichhornia crassipes), either accidentally or deliberately 17,18 .

River damming is expected to proliferate across Tropical American Rivers in the forthcoming decades with expected declines in ecosystem health to costly invasive species. Historical data and modern aquatic plant surveys of one of the largest and oldest tropical dam projects (the > 100 years old Panama Canal) reveal that modern plant communities in areas adjacent to terrestrial Natural Protected Areas (tNPAs) retain a pre-damming community structure that is apparently more resistant to invasive species. Establishing tNPAs adjacent to impounded rivers could be a cost-effective nature-based solution for tropical reservoir management.

“…native species decline, displacement, extirpations, diseases etc) (Hanley and Roberts, 2019). Compared to mammals and birds, sh invasions and their introduction vectors are well studied, with high numbers of publications and reported numbers of alien species (Semmens et al, 2004;Castellanos-Galindo et al, 2020). The low number of reported costs for sh invasions inferred from this large body of research likely re ects the fact that some shes, unlike most birds or mammals, are purposefully introduced .…”

Invasive alien fishes have caused pernicious ecological impacts on aquatic ecosystems. However, there has not been a global appraisal of associated economic impacts. Here, we compiled reported economic impacts of invasive alien fishes using the most comprehensive global database of invasion costs (InvaCost). We analyze how fish invasion costs are distributed geographically and temporally, as well as which socioeconomic sectors are most impacted. Fish invasions have caused the economic loss of at least US$32.8 billion globally (2017 value), from only 26 reported species (of 128 known invasive alien fish species). North America had the highest costs (> 99%), followed by Europe and Asia, with no costs reported in Africa, Oceania nor South America. Very few costs from invasive fish in the marine realm were reported (0.1%). Most costs are related to resource damages and losses (97%), with relatively little spent on management; mainly impacting the fisheries sector (93%). However, when only considering empirically observed costs (without predictions), most costs were incurred by authorities and stakeholders through management, indicating that damage costs from invasive fishes are often extrapolated and/or difficult to quantify. Fish invasion costs increase markedly over time, from US$0.57 billion/year in the 1980s to US$1 billion/year in the 2000s. Fish invasions have been relatively well studied; however, economic costs have been lower than expected based on overall numbers of alien species. Accordingly, although costs are increasing, improved reporting is required to better understand how fish invasion costs are distributed across time, space and economic sectors.

“…They are considered one of the greatest threats to global marine ecosystems, affecting their structure and function (Costello et al, 2010), with negative socioeconomic consequences (e.g., Gherardi et al, 2011). Ballast water and hull fouling, associated with maritime transport, are responsible for the vast majority of accidental marine translocations around the world (Carlton, 2001;Hewitt et al, 2009;Seebens et al, 2013), however, there are other human-mediated pathways that can be used by species to spread to new habitats, such as the opening of new corridors that facilitate the spread of species (Steger et al, 2019;Castellanos-Galindo et al, 2020) or escapes from aquaculture facilities (Thorvaldsen et al, 2015;Ju et al, 2020) among others.…”

Invasive alien species (IAS) are currently considered one of the greatest threats to global marine ecosystems. Thus, ships and maritime activity have been identified as the main factors responsible for the vast majority of accidental species translocations around the world, implying that prevention should be the core of environmental port policies. Preventive port strategies should include analyzing risks based on traffic origins and volumes, revising port policies for inspections, estimating probabilities of non-indigenous species (NIS) appearance, monitoring routine species within ports, and finally implementing management plans and focused actions. Here, we conducted a comprehensive NIS prediction analysis for the port of Gijon (northern Spain), one of the largest ports in the south Bay of Biscay, as a case study that can be extrapolated to other international seaports. An extensive bibliographic search (1953–2020) was conducted and we identified 380 species that have been transported through hull fouling and ballast water around the world. We evaluated their likelihood of arriving (from 14 years of traffic data) and becoming established (from habitat suitability and demonstrated impacts and invasion ability) within the Gijon port, creating a new NIS Invasion Threat Score (NIS-ITS). This new index could help to identify target species that are likely invaders for early detection and prevention policies within the port. The results showed that 15 NIS had >90% likelihood of becoming a biological invasion problem in Gijon Port. At the same time, we reported morphological and genetic analysis of biota found in two successive annual monitoring surveys of Gijon port and ships (n = 612 individuals) revealing 18 NIS, including 6 of the NIS predicted from high NIS-ITS. Actually, 80% (12 NIS) of those potentially most dangerous species (NIS-ITS > 90%) have already been detected in the Bay of Biscay area. We propose the use of this new tool for a risk-reduction strategy in ports, based on accurate predictions that help in promoting specific early detection tests and specific monitoring for NIS that have a high chance of establishment. All international seaports can adopt this strategy to address the problem of biological invasions and become “blueports” in line with EU policy.
