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: In Europe, invasive freshwater crayfish are causing local extinctions of native crayfish, particularly in Italy. A successful reintroduction of white-clawed crayfish in an isolated Italian stream showed significant growth in population and successful breeding within a short period of time. Effective reintroduction actions involve stakeholder engagement and monitoring of environmental conditions.

Summary: This study examines the impact of crayfish plague on the interaction between noble crayfish and invasive species. The results show that noble crayfish has an advantage over invasive species in agonistic behavior and shelter competition. Therefore, if crayfish plague no longer eradicates noble crayfish populations in the future, noble crayfish still has the potential to succeed in competition with invasive species.

Summary: The intrusion success of the invasive crayfish species in competition against the native species is attributed to its more effective anatomical features, leading to bolder behavior. In contrast, the native species relies on intimidation display despite having larger chelae and better muscular tissue performance.

Summary: The study found that regulated river reaches typically have higher numbers of the spiny cheek crayfish, possibly due to reduced food-web complexity and the lack of predators in a homogenised habitat.

Summary: Both age and sex of crayfish have significant effects on the accumulation of Ca, Cu, and Zn in the muscle and exoskeleton. The concentrations of these metals in the muscle and exoskeleton are influenced by physicochemical and biological factors. The consumption of spiny-cheek crayfish meat is safe in terms of the analyzed metal content.

Summary: In this study, crayfish meat was fermented with strains of Lactiplantibacillus plantarum, Lacticaseibacillus rhamnosus, Lactobacillus casei, and yogurt culture. The effects of fermentation on microbial quality, amino acid content, sugars, ascorbic acid, and antioxidant properties were evaluated. Changes in canthaxanthin content, sulfhydryl groups, and disulfide bridges were also assessed. The results showed that lactic fermentation resulted in decreased pH, increased antioxidant activity, and positive effects on sulfhydryl groups and ascorbic acid content. These findings provide a foundation for the development of fermented products using crayfish meat.

Summary: This study investigates the phenotypic variability of two invasive crayfish species in 23 gravel pit lakes in southwest France. The results reveal contrasting variance distribution patterns and adaptation mechanisms between the two species across different ecological scales. The findings emphasize the importance of studying invasive species to gain insights into intraspecific variability and its ecological determinants.

Summary: The aim of this study was to evaluate the possibility of using extracts from the spiny-cheek crayfish as natural antioxidants. The results showed that the extract had antioxidant activity and could reduce oxidative stress-induced cell damage.

Summary: This study investigated the impact of dam reservoirs on the body condition of invasive Faxonius limosus. The results showed that reservoirs have a positive allometric effect on the growth of females, but have a less significant impact on males. Contrary to expectations, reservoirs do not provide more favorable habitat conditions for F. limosus compared to natural aquatic environments.

Summary: The study evaluated the seasonality of diet and trophic niche of invasive signal crayfish in the Valla Stream, finding that both adults and juveniles mainly rely on macroinvertebrates and periphyton in summer, shifting to mostly periphyton in autumn. Juveniles showed slightly different carbon isotope values and exhibited seasonal feeding habits consistent among seasons, suggesting potential ecological behavior rather than food resource availability. No significant differences were found in adult and juvenile diets between summer and autumn, indicating similar effects on macroinvertebrate communities in the stream ecosystem.

Summary: Crayfish plague is a devastating infectious disease that has caused the decline of crayfish populations. Some European crayfish populations have shown resistance to the disease, similar to North American crayfish. In the Iberian Peninsula, southern populations exhibit different responses to the pathogen compared to northern and central populations.

Summary: Habitat fragmentation poses a pervasive threat to biodiversity, particularly for linearly arranged habitats like stream networks. This study finds that small tributaries can rescue or slow down the extinction of specific populations in highly fragmented stream networks. The findings have important implications for the conservation of headwater populations and aquatic biodiversity.
