“…In this specific situation, the restoration of habitat may not be effective to counteract the presence of alien rheophilic species, unless combined with their control (e.g. Capdevila‐Argüelles et al, 2011; McColl & Sunarto, 2020; Rytwinski et al, 2019). In light of the complexity of alien species behaviour, we believe our findings could help inform alien species management decisions in the region.…”

1. Freshwater fish biodiversity is experiencing an alarming decline worldwide.Understanding the main factors behind its deterioration is a key step for ecosystem restoration. In this work, large-scale and long-term data were used to identify the causes of the decline of native species richness in Castilla-La Mancha.This region in central Spain covers part of six river basins belonging to four of the 11 biogeographical provinces for freshwater fish in the Iberian Peninsula.2. Firstly, we built a dataset that associates the presence of several fish species and a wide range of environmental variables (e.g. hydrological and hydromorphological indicators, land use classes, presence of alien fish species) at selected river sites for two different time periods (1980-2000 and 2001-2020). Secondly, we conducted an exploratory data analysis to identify possible temporal trends in the dataset. Finally, we applied the random forest algorithm to predict the response of different ecological guild-based metrics of fish richness to the selected variables.3. The exploratory data analysis revealed a decrease in native fish species richness in 74% of the area studied. There was no sustained temporal trend for stressor variables, except for the number of alien species, which increased in most river sites (63%). The models of the richness of native rheophilic, native intolerant, alien rheophilic, and alien limnophilic species performed satisfactorily. Magnitude of maximum discharge, presence of alien species, land use in the catchment area and altitude were the most important predictors of richness of native intolerant and rheophilic species. Alien limnophilic species proved to be sensitive to variables related to flow regime alteration, such as the presence of dams and the number of river flow reversals, while a less degraded habitat was found to be favourable to alien rheophilic species.4. The results suggest that the cumulative effect of persistent altered flow regimes and water pollution, coupled with a strong increase in the number of alien species, have led to the decline of native species in the area studied.

“…Biotic control techniques include new techniques to locate/attract and remove adults (ex., "Judas fish" [3,7]); techniques to remove/kill eggs/young using native microbes, etc. [11]; enhanced/targeted fishing [4]; introduction of new predators or management of extant ones, especially predators for vulnerable young [3]; and introduction of novel pathogens [12]. Important abiotic approaches include the strategic use/development of new piscicides (fish poisons) [13], and the development of physical techniques to selectively block movement/migration of invasive fish into new areas where they might breed successfully [14,15].…”

Across the globe, dozens of species of invasive fish are now found in fresh as well as marine waters, where they alter habitats, compete with native fish for food, and prey on native fishes, exerting both indirect and direct effects on ecosystems and economies. While efforts to understand and control these species are growing, most are still in their infancy; however, a few examples stand out. This special issue is comprised of 11 notable articles on freshwater invasive fish and is the first to address this topic. This introductory article serves as an introduction to these articles which focus on 5 topics on invasive freshwater fish: (1) the damage they cause (one article); (2) techniques to ascertain their presence (one article); (3) techniques to restrict their movement (one article); (4) strategies to control them (three articles); and (5) lessons learned from ongoing management efforts (five articles). This introduction notes that successful management efforts share a few approaches: (1) they develop and use a deep understanding of local species and their abundance as well as distribution; (2) they focus on reducing reproductive success; (3) they use multiple complimentary control strategies; and (4) they use a long-term approach.

Cyprinid herpesvirus‐3 (CyHV‐3) is an important pathogen of common carp (Cyprinus carpio, carp) causing significant economic and ecological impacts worldwide. The recent emergence of CyHV‐3 in the Upper Midwest region of the United States has raised questions related to the disease ecology and host specificity of CyHV‐3 in wild carp populations. To determine the prevalence of CyHV‐3 in wild populations of fishes in Minnesota, we surveyed five lakes in 2019 in which the virus was known to have caused mass mortality events in carp from 2017 to 2018. A total of 28 species (n = 756 total fish) of native fishes and 730 carp were screened for the presence of CyHV‐3 DNA using specific qPCR. None of the native fish tissues tested positive for CyHV‐3 although the prevalence of CyHV‐3 in carp was 10%–50% in the five lakes. A single lake (Lake Elysian) with a 50% DNA detection rate and evidence of ongoing transmission and CyHV‐3‐associated mortality was surveyed again in 2020 from April to September. During this period, none of the tissues from 24 species (n = 607 total fish) tested positive for CyHV‐3 though CyHV‐3 DNA and mRNA (indicating viral replication) was detected in carp tissues during the sampling period. CyHV‐3 DNA was detected most often in brain samples without evidence of replication, potentially indicating that brain tissue is a site for CyHV‐3 latency. Paired qPCR and ELISA testing for Lake Elysian in 2019–2020 identified young carp (especially males) to be the primary group impacted by CyHV‐3‐associated mortality and acute infections, but with no positive detections in juvenile carp. Seroprevalence of carp from Lake Elysian was 57% in 2019, 92% in April of 2020 and 97% in September 2020. These results further corroborate the host specificity of CyHV‐3 to carp in mixed wild populations of fishes in Minnesota and provide additional insights into the ecological niche of CyHV‐3 in shallow lake populations of carp in North America.
