Summary: Invasive non-indigenous crayfish species pose a significant threat to native crayfish populations in European freshwater ecosystems. The presence of signal crayfish, marbled crayfish, and spiny-cheek crayfish in Estonia has increased the risk of extinction for the native noble crayfish. This study provides an overview of the status, distribution, and impacts of these invasive species on native crayfish populations, as well as the effectiveness of trapping in controlling their abundance.

Summary: The noble crayfish, an indigenous European freshwater species, is facing significant declines in population due to human activities, climate change, and invasive species. A study combining population genetics and species distribution modelling revealed the impact of climate change on the species and highlighted the need for effective conservation measures. The study found that Croatian populations of the noble crayfish harbor important genetic diversity but are predicted to experience substantial reductions in suitable habitats in the future. The results emphasize the importance of identifying and protecting areas with high conservation value, as well as considering assisted migration and repopulation approaches to preserve genetic diversity.

Summary: Transformation of food systems is necessary for feeding the growing global population. The rice-crayfish integrative system (RCIS) allows for the production of multiple types of food on the same land area and has gained popularity in Asian countries. However, there is limited information regarding the distribution of crayfish in paddy fields, which is crucial for effective management. This study conducted a 2-year field experiment and found that crayfish distribution in RCIS is influenced by water depth and field topography, with the highest densities observed in gullies near the short ridge of rectangular farmland.

Summary: Floodplain ecosystems host diverse habitats that support high species diversity, including burrowing crayfish which play a key role in aquatic-terrestrial connections. The presence of active burrows is strongly associated with groundwater depth, while crayfish species composition may vary with flooding frequency. Different species associated with surface waters and burrowing coexist in floodplains, indicating the diverse habitat requirements met by environmental features.

Summary: In endangered crayfish conservation projects, it is important to map the distribution of the crayfish plague pathogen Aphanomyces astaci in native populations. This study explored non-invasive sampling techniques, such as environmental DNA (eDNA) analysis and cuticular swabbing, to detect A. astaci. The findings suggest that filtering 5 liters of water with filters of 2.7 μm porosity for eDNA analysis and using cuticular swabs are effective methods for sampling. Storage in absolute ethanol is recommended for preserving samples. Integrated sampling methods are suggested for monitoring A. astaci in conservation efforts.

Summary: The distribution and influencing factors of antibiotic resistance genes (ARGs), especially high-risk ARGs, in the gut of aquaculture animals remain unclear. In this study, we used 16S rRNA gene sequencing and high-throughput quantitative PCR techniques to determine crayfish gut microbiota and ARGs collected from 40 culture ponds in major crayfish farming provinces of China. Our results illustrate that ARGs are prevalent in crayfish gut and may pose potential risk to human health, which will help develop targeted strategies for the risk management and assessment of ARGs in the aquaculture.

Summary: This study aims to assess how habitat alteration and subsequent water quality changes affect the stone crayfish population in the Kustosak Stream (Croatia) through three selected sites under different levels of anthropogenic disturbance. The results showed that habitat alteration caused an overall reduction in population abundance and changes in size structure, however, it had not yet resulted in detectable genetic differences. Crayfish abundance was affected by the physicochemical parameters of water, including oxygen, calcium ions, nitrates, pH, and water temperature.

Summary: This study found that the Crna Mlaka fishponds in Central Croatia are at a high risk of being invaded by non-native water frog species, leading to introgressive hybridization and genetic admixture. The presence of hybrid forms and introgressed mtDNA indicates the existence of a unique hybrid swarm in this location. The loss of the hybridogenetic reproductive system of Pelophylax kl. esculentus is also observed.

Summary: Cardiovascular pharmaceuticals (CVPs) have been detected in inland waters and fish in the Sava River, Croatia. The effects of CVPs (specifically amiodarone, ramipril, simvastatin, and verapamil) on zebrafish embryos were investigated, and their survival, development, and physiological changes were monitored. SIM had the highest mortality and pathological effects, which were consistent with the effects observed in zebrafish exposed to CVP mixtures. All pharmaceuticals affected cardiac function and decreased heart rate. SIM, VER, and RAM decreased larval length, while SIM and VER exposure induced oxidative stress. Behavioral alterations were only observed in the AMI-treated group. The study highlights the risk of CVPs, especially statins, for fish in inland waters.

Summary: Eiseniella neapolitana is a semi-aquatic, diploid earthworm that was previously considered a subspecies of Eiseniella tetraedra. Our study using molecular markers and morphology confirmed the synonymy between Eiseniella and Norealidys. Genetic analyses revealed the separation between E. neapolitana and E. andaluciana (= N. andaluciana), and disproved that E. neapolitana is a subspecies of E. tetraedra.
