Summary: This study examined the effects of in situ exposure to municipal wastewater treatment plant effluents on juvenile yellow perch in the St. Lawrence River. Results showed that perch exposed to effluents had increased body condition, different muscle isotopic compositions, and varying metal concentrations over time. Liver metabolites differed between exposed perch and laboratory controls, suggesting a caging effect on fish. The combination of metabolomics and physiological variables was useful in understanding the impacts of complex environmental pollutant mixtures on wild fish.

Summary: This study compared the skeletal muscle proteomic profiles and expression levels of myogenic regulatory factors between fast- and slow-growing yellow perch, identifying different expression patterns in relation to muscle growth dynamics. Fast-growing perch exhibited greater body weight, muscle fiber hypertrophy, mosaic hyperplasia, and higher expression of metabolic enzymes and myogenic regulatory factors compared to slow-growing fish.

Summary: This study investigated the effects of high-density polyethylene (HDPE) on yellow perch and found that HDPE did not significantly affect the growth of the fish. However, dietary exposure to HDPE decreased the nutritional quality of the fish, altered nutrient metabolism, and affected the intestinal histopathology and microbiota community.

Summary: Estuaries are important habitats for coastal fish species, and the recruitment of larvae and early juveniles into estuaries is crucial for population persistence. This study found that settlement-stage A. japonicus prefer turbid water over clear water when recruiting into estuaries, suggesting that turbidity gradients play a major role in their recruitment.

Summary: This study investigated the response of the hamp gene in yellow perch to lipopolysaccharide challenge in males and females. The results showed that female yellow perch had an earlier but less-sensitive response to lipopolysaccharide challenge compared to males.

Summary: The study provides insights into the foraging habits of Indo-Pacific bottlenose dolphins in south-western Australia, showing selective feeding behavior with a preference for Gobiidae species. Stable isotope analyses revealed niche differentiation between coastal and inshore dolphins, with coastal dolphins having a more pelagic diet and inshore dolphins feeding on enriched prey typical of estuarine environments.

Summary: This study identified the mucin-microbiome signatures in gastric adenocarcinomas and their impact on clinical outcomes. The findings showed that intestinal mucin phenotype and high-level MUC13 expression were associated with poor survival, while gastric MUC5AC or MUC6 abundance was associated with a more favorable outcome. Furthermore, oral bacteria such as Neisseria, Prevotella, and Veillonella were found to play a potential role in MUC13 signaling and were associated with intestinal and mixed mucin phenotype tumors.

Summary: Kelp habitats are important for marine productivity and diversity, but their distribution is influenced by sediment levels. Increasing sediment decreases the proportion of attached spores that develop, but attachment and density of gametophytes increase for Saccharina. However, sediment effects on early life stages do not explain differences in adult distribution, and further investigation with higher sediment loads is needed.

Summary: Infection with eye flukes can lead to increased diet selectivity in European perch, with intensively infected fish showing preference for specific prey, while less intensively infected fish behave as generalist feeders with no particular prey preference in their diet. This highlights the indirect effect of parasites on the host's interaction with lower trophic levels and emphasizes the underestimated role of parasites in food web studies.

Summary: Understanding the sensory ecology of species is crucial for predicting their function in a changing environment. Visual cues play a vital role in prey detection and capture for many predators. However, climate-induced turbidity in marine areas can potentially affect the ability of marine predators to detect prey. This study examines the relationship between a pelagic seabird species's foraging behavior and oceanic turbidity, finding that underwater visibility strongly influences foraging dives and prey detection, suggesting climate change could negatively impact seabird populations.

Summary: This study found that 0.0125% fipronil bait is repellent against S. invicta workers, and higher concentrations of fipronil should be avoided in fire ant bait production. The effect of active ingredients and their concentrations on bait acceptance should be considered in future studies evaluating the effectiveness of fire ant baits.

Summary: Genetic architecture and phenotypic plasticity are important factors when studying trait variation and its interaction with environmental factors. DNA methylation shows plasticity and gene-specific effects in different rearing environments, indicating developmental stage-specific influences of environmental factors on DNA methylation. Understanding genetic and environmental influences on methylation is crucial for future studies on acclimation and adaptation mechanisms.

Summary: The study revealed that the gut microbiota composition of stocked and wild salmon from the same genetic population and environment depended on the early rearing environment, while the skin microbiota of stocked individuals converged towards that of wild individuals. Taxonomic composition and co-occurrence network analyses suggested an impairment of wild bacteria recruitment and higher instability for the gut microbiota of stocked parr. This study emphasized the long-term effect of early microbiota ontogeny in artificial rearing for natural population conservation programs, highlighting the need for implementing microbial ecology.

Summary: Captive-breeding programs, although effective in mitigating biodiversity loss, can result in genetic and nongenetic changes that reduce the fitness of supplemented individuals. This study investigated the reproductive success and genetic diversity of Atlantic salmon stocked at the parr stage in Quebec, Canada. The findings suggest that parr-stage stocking leads to reduced reproductive success compared to wild salmon, but still improves relative reproductive success compared to other stocking practices. Additionally, the supplementation of captive-bred salmon significantly contributes to increasing genetic diversity.

Summary: Human activities and resource exploitation have led to a decline in wild salmonid populations. Conservation programs have been developed to supplement wild populations, but studies have shown reduced fitness of hatchery-born fish compared to wild fish. This study uses RNA sequencing and Whole Genome Bisulfite Sequencing to investigate gene expression differences between hatchery and wild-born Coho salmon. The results suggest that early-life hatchery-rearing environment-induced gene expression differentiation is maintained until the fish return to their natal river. The study highlights the importance of considering both the epigenome and transcriptome in large-scale supplementation programs.

Summary: This study investigates the effects of parental and offspring temperatures on DNA methylation in brook charr. The results show that parental maturation temperature has a significant impact on offspring methylation, while offspring rearing temperature has a minimal effect. The intergenerational inheritance of DNA methylation could facilitate adaptation to a warming environment.

Summary: This study compared the reproductive success of caught-and-released Atlantic salmon to non-caught salmon and found that the reproductive success of caught-and-released females was lower. The temperature at release did not affect the reproductive success of released fish, but warmer temperatures made fish less likely to enter a trap.

Summary: Doubled haploid gynogens are individuals with two identical maternal chromosome sets and no paternal genetic contributions. They are useful in whole-genome sequence assembly to eliminate allelic variation. This study successfully determined the timing for producing doubled haploid gynogens in multiple salmonid species and assessed their survival rate and genotypes.
