Summary: This study confirmed the co-introduction of two dactylogyrids, Dactylogyrus squameus and Bivaginogyrus obscurus, and a newly described gyrodactylid species, Gyrodactylus pseudorasborae n. sp., into Europe along with their fish host from East Asia. G. pseudorasborae n. sp. was found to have a relatively higher prevalence and abundance compared to the other two species. Genetic and morphometric analysis were used to differentiate between the two gyrodactylid species. In addition to the co-introduced parasites, the invasive fish host was also infected with a local monogenean species.

Summary: Iran serves as an important location for the genetic diversity and colonization history of the topmouth gudgeon, P. parva, with distinct lineages from China and Japan intermingling in the country's inland waters. Despite low genetic diversity within Iranian populations of P. parva, there is evidence of admixture leading to higher diversity in the Caspian Sea and Esfahan basins. This study highlights the potential presence of multiple putative species within the native range of P. parva, calling for further taxonomical investigations.

Summary: Invasive fish pose a threat to the ecological status and ecosystem services of ponds, making it crucial to accurately assess the composition of fish communities. This study compared three different sampling methods - electrofishing, fish-trapping, and throw-netting - to estimate the size distribution, density, and biomass of the invasive fish species, Pseudorasbora parva. The results showed that all three methods successfully detected P. parva, but there were significant differences in population characteristics estimates among the methods. Fish-trapping was found to be the most reliable and cost-effective method for estimating P. parva population characteristics in ponds, despite requiring more time for sampling. The study emphasizes the importance of selecting appropriate sampling gear for monitoring invasive fish in ponds.

Summary: In visual search tasks, negative features help participants locate the target by suppressing stimuli sharing the negative feature, as reflected in the P-D component of the event-related potential. However, the P-D occurs only when the target and distractor can be on opposite sides of fixation, suggesting that participants strategically avoid the distractor by selecting stimuli on the opposite side.

Summary: This study investigates the performance of visual attention tracking and neural oscillatory characteristics in ice hockey players by changing the movement speed of the athletes. The experimental results indicate that higher movement speed leads to lower tracking accuracy and lower ERSP value of the high-frequency alpha rhythm. This demonstrates the impact of speed on the inhibitory effect of nontarget tasks, which is beneficial for athletes to suppress interference information and improve sports performance.

Summary: This study optimized and validated a quick, easy, cheap, effective, rugged, and safe (QuEChERS) pretreatment method for screening organophosphate esters (OPEs) in wild fish samples from Taihu Lake in China. The research identified 20 OPEs, with 9 emerging OPEs detected in wild fish for the first time. The results indicate that emerging OPEs such as TDtBPP, IPDP, and BPDP may play an equally important role as traditional OPEs in contributing to OPE pollution in wild fish samples.

Summary: Genetically engineered gene drives (geGD) are powerful tools for controlling pest insects, but before their release, it is important to assess the potential risks to non-target species and ecosystem services. Hybridization experiments, behavioral observations, and genetic analyses can be used to study the likelihood of gene flow between geGD insects and related species. Using the case of spotted-wing drosophila, we demonstrate a strategy for assessing the potential for hybridization.

Summary: This study demonstrates the negative impacts of rotenone on crustacean zooplankton and macroinvertebrate species in a mountain lake, lasting for at least a year after treatment. Unique insights include almost complete eradication of crustacean zooplankton 11 months after rotenone treatment, and a considerable shift in macroinvertebrate community composition likely due to nontarget effects and trophic interactions associated with trout eradication. Assisted recolonization may play a crucial role in facilitating nontarget aquatic community recovery post-rotenone treatment.

Summary: The Emergency Recovery Plan for freshwater biodiversity recognizes that addressing nonnative species is one of the key actions to prevent loss of freshwater biodiversity. The plan emphasizes the importance of preventing introductions of nonnative species, but also highlights the need for early detection and rapid reaction measures in case of introduction. Control and containment measures are recommended for invasive species, along with invasion risk assessment and species-specific eradication methods.

Summary: Behavioural thermoregulation allows freshwater fish to adapt to different temperature environments, especially in extreme thermal conditions. Fish of different species and spatial scales move in response to temperature changes, with age and migratory ability affecting their tolerance to temperature differences. Research has primarily focused on studying the behavior of cold-water salmonids during summer, leaving a need for further study on the thermoregulatory behaviors of other non-salmonid fishes in warming conditions.

Summary: Biological invasions are a significant component of global change, but they can also have negative impacts on native populations. Efficient management policies are needed to prevent the spread of invasive species in non-native areas while protecting native populations. Genetic variation analysis can help assess the genetic state, identify invasion pathways, determine management strategies, and identify populations requiring conservation measures.

Summary: This study provided the first genome-wide characterization of genetic diversity in the European range of sea lamprey. It revealed a single metapopulation that includes freshwater spawning sites within the North Eastern Atlantic and the North Sea, with some limitations to dispersal at northern latitudes. The study also found that oxygen concentration and river runoffs impose spatially varying selection pressures across their distribution range in the ocean.

Summary: The timing of entry into freshwater by mature anadromous fishes is determined by migration cues, particularly photoperiod, and shows high individual repeatability. This study used passive acoustic telemetry to track 71 twaite shad returning to the River Severn's upper estuary over multiple spawning seasons, and found that the timing of river entry was consistent between years and strongly predicted by increasing day length. Water temperatures and flow rates, however, were weak predictors and highly variable between years. The results highlight the importance of understanding migration cues and their variability in assessing the migration phenology of anadromous species.

Summary: The global COVID-19 pandemic led to restrictions on people's movements in many jurisdictions, affecting recreational angling. After the restrictions were lifted, initial surveys suggested increased participation and altered angler demographics, but evidence remained limited. This study examines changes in angling interest, licence sales, and angling effort in different regions during the 'pre-pandemic,' 'acute pandemic,' and 'COVID-acclimated' periods. It suggests that efforts to retain younger anglers and provide more urban angling opportunities could increase overall participation levels and enhance resilience in recreational fisheries.

Summary: The bleak Alburnus alburnus is a medium-sized leuciscid fish that is naturally distributed across central European and western Asian fresh waters. It has been widely introduced in Europe and northern Africa as a forage species for game fishes. In its native range, it feeds mainly on zooplankton, but non-native populations show high phenotypic plasticity in their biological attributes, adapting to local environmental conditions and invading different ecosystems. This plasticity, coupled with broad physiological tolerance, is likely to facilitate its adaptation and invasion of new habitats in the future.

Summary: Non-lethal sampling methods can be used for trophic studies on inshore flatfish populations of high value. Fin tissue and epidermal mucus can serve as alternatives to muscle for stable isotope analysis. Differences in isotopic values can be predicted and converted using linear regression. These tissue alternatives allow for non-lethal sampling and analysis of flatfish populations.
