Summary: The presence of North American alien crayfish in Europe has led to declines in native crayfish populations due to their role as carriers of Aphanomyces astaci, the pathogen responsible for crayfish plague. In Czechia, screening for A. astaci revealed new hotspots of infected crayfish and the potential for interspecific transmission between different crayfish species. Despite fluctuations, A. astaci prevalence in North American host populations generally does not vary significantly over time, with some populations still posing a threat to native crayfish.

Summary: Immune defence is crucial for organismal fitness. Theoretical models predict stabilizing selection on quantitative immune traits, but empirical studies observe positive directional selection. This study investigates how selection on immune function varies depending on immune challenge, immune traits and populations in freshwater snails. The results show that immune challenge and specific immune traits determine the selection on snails' immune function. Furthermore, there is low differentiation among populations but high genetic variation within populations of immune traits.

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: This study found that native crayfish populations of A. pallipes host a greater diversity of parasites compared to invasive species P. leniusculus. The prevalence of A. astaci in A. pallipes populations was higher in more polluted water bodies, possibly due to the effect of water quality or increased chance of transmission from nearby P. leniusculus.

Summary: Host-associated microbial communities are important for individual fitness and invasive species success. This study compared the exoskeletal microbial communities of native and invasive crayfish species, finding significant differences in composition and abundance. However, a majority of bacterial genera were present in both native and invasive crayfish. Additionally, low amounts of known crayfish pathogens were detected, and a non-standard ddPCR protocol showed better performance for testing under low concentration conditions.

Summary: The study investigated temperature-specific feeding and metabolic rates of invasive and native crayfish, finding that the metabolic rates of native crayfish were significantly higher at low temperatures than the rates of invasive crayfish. Results indicate that the invader's thermal niche has remained stable and the potential impacts per capita are lower at suboptimal cold temperatures than for the native species.

Summary: Little is known about how particle chemical composition and size might influence the toxicity of nanoscale plastic debris (NPD) and their co-occurring chemicals. In this study, the toxicity of different types of NPD and their co-occurring chemical, benzo(alpha)pyrene (BaP), on Daphnia magna and Danio rerio were investigated. The results showed that different types of NPD had varying effects on the reproduction of D. magna and hatching rate of D. rerio embryos. The presence of BaP also influenced the toxicity of NPD. These findings suggest that the toxicity of one type of NPD cannot be extrapolated to other types.

Summary: Similar to other aquatic ectotherms, freshwater mussels are prone to the predicted global warming of surface waters. Sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA) has a crucial role in regulating intracellular Ca2+ concentration in muscle cells and potentially involved in setting thermal preferences and behaviors of animals. SERCA activity of adductor and foot muscles in two freshwater mussel species, Anodonta anatina and Unio tumidus, was examined under different acclimation temperatures. The results showed significant differences in SERCA activity between the two species and different tissues. Cold-acclimated individuals tended to conserve energy by turning off SERCA activity in the muscular foot. Strong temperature-dependent up- or down-regulation of muscle SERCA activity in mussels is probably associated with species-specific behaviors and has implications on freshwater mussel aquaculture and conservation.

Summary: Aquaculture is a resource-efficient and sustainable method to produce animal protein, and it is predicted to play a significant role in the world's seafood supply. However, the growth of intensive aquaculture may be limited by a shortage of feed resources. This review explores the urgent need to find alternative ingredients for sustainable salmonid production. Various marine ingredients, microbial ingredients, insects, animal by-products, and by-products from other commercial productions are discussed as potential alternatives.

Summary: Plastic pollution is a major aspect of global environmental issues, which has adverse effects on aquatic organisms and ecosystems. This study investigates the potential influence of nano-sized plastic particles on the reproductive biology and offspring traits of fishes. The results suggest that the exposure of gametes to plastic particles slightly increases the body length of larvae but does not affect embryo mortality, hatching time, and larval swimming performance.

Summary: Management of inland recreational fisheries can benefit from data on stock abundance and size structure. Ice fishing, using standardized angling methods, can provide information on the abundance of different-sized fish in small lakes. Our study found that the length distribution of fish caught through ice fishing was similar to the traditional gillnets method, indicating it can be a valid indicator for management purposes.

Summary: We have developed an epidemiological model for understanding the dynamics of crayfish plague, a lethal disease caused by the oomycete Aphanomyces astaci. The pathogen exhibits high virulence and can cause significant mortality in crayfish populations across the world. Our study shows that the complex dynamics of the disease are influenced by various transmission routes, including cannibalism and scavenging of infected carcasses. Environmental transmission is found to be the main factor driving epidemics.

Summary: Threatened fish populations worldwide are relying on stock supplementation by hatchery-reared fish. Hybridization with non-native fish may improve the adaptive potential of small populations, as shown in this study with critically endangered Finnish landlocked salmon. The hybrids displayed intermediate behaviors compared to purebred salmon, indicating heritability of boldness-related traits. This research suggests that hybridization could help reverse negative behavioral traits in landlocked salmon.

Summary: The fragmentation of plastic waste can result in the formation of nanoscale plastic debris (NPD) of size < 1 μm. However, the toxicokinetics of NPD is not well understood, particularly regarding its passage through physiological barriers and its biodistribution, biotransformation, and excretion from organisms. Although new methods and techniques are being developed to gain insights into the uptake and toxicokinetics of NPD, the necessary knowledge is being generated slowly, which hinders environmental risk assessment. This perspective outlines the current understanding of the toxicokinetics of NPD in organisms, discusses the knowledge gaps, and highlights the research needed to address them. Additionally, it presents a perspective on toxicokinetics modeling of NPD using physiologically based pharmacokinetic (PBPK) models and provides recommendations for developing PBPK models for NPD, taking into consideration various influencing factors.
