Summary: Pacific lamprey populations are declining and contaminants may be a contributing factor. Organohalogenated compounds were detected in all life stages of Pacific lamprey, indicating potential sources of pollution. Concentrations of some compounds in returning adult lamprey, a significant food source for Indigenous peoples, exceeded consumption thresholds.

Summary: Blood biochemistry and haematological parameters in fish are affected by environmental changes, stress, and health status. The study provides baseline data and reference ranges for 34 indicators in Chinook salmon, showing significant differences in some parameters between freshwater and seawater environments. Some parameters were also found to be correlated with fish size.

Summary: This study quantifies the impact of anthropogenic noise on Pacific herring and juvenile salmon, showing that they exhibit antipredator responses when exposed to boat noise. Repeated elicitation of vigilance or anti-predatory responses may result in increased energy expenditure or decreased foraging.

Summary: A four year study in Cowichan Bay, Canada found potential linkages between phytoplankton composition and abundance and the feeding and histopathology of juvenile salmon. Dense blooms of certain species of algae led to reduced feeding in Chinook salmon, and damage to gills and pathological changes in livers.

Summary: This study examines the environmental dependency and sustainability of wild caught sockeye salmon fishery in Alaska and Atlantic salmon aquaculture in Norway. The results indicate that labor and services have a significant impact on both production systems at the processing stage, with a high emergy sustainability index (ESI) for the sockeye fishery.

Summary: Juvenile sockeye salmon migrating near salmon farms in the Discovery Islands region of British Columbia show high detection rates of the bacterium Tenacibaculum maritimum. The infection pressure from farmed salmon is significantly higher than from other sources, indicating the need for better management of farm-wild interactions.

Summary: In this study, 94 Renibacterium salmoninarum (Rs) genomes from Chile were compared and analyzed using bioinformatics tools, resulting in the identification of 2199 independent single-nucleotide polymorphisms (SNPs). Based on these SNPs, multiplex PCR primers were designed and sequenced to determine the genotype of the corresponding sub-lineage, providing a rapid and reliable method for studying the relationships between Rs isolates without the need for whole genome sequencing.

Summary: The study investigates escape incidents from Norwegian fish farms between 2010 and 2018, finding that most incidents are caused by technological factors, with net hole breakage being the most common cause of escape. These incidents may also have underlying human and organizational factors contributing to the escapes.

Summary: This study found antibiotic residues in both farmed salmon and wild trout from Chile, with higher concentrations in wild fish. Different patterns of antibiotic residues were observed between farmed and wild specimens. Multivariate statistical analysis was used to identify differences between farmed and wild populations, and to determine the probable sources of antibiotics.

Summary: Salmonid aquaculture has expanded globally in recent decades, with changes in cage technologies and locations. This study used satellite images to analyze the changes in cage size, location, and proximity to neighboring farms. The results showed that cage diameters have increased, leading to larger farms, while the distance to neighboring farms varied across regions. These changes have environmental and production consequences, emphasizing the importance of analyzing and improving management practices in salmon farming.

Summary: Submerged cages are becoming a new trend in marine aquaculture due to their ability to reduce issues associated with surface-based cages. Fish with closed swim bladders and without swim bladders are more suitable for submerged culture, while fish with open swim bladders may face more challenges in this process.

Summary: The study tested three types of dried algal supplements on the color, taste, and gonad quality of temperate urchins, finding that while all feed types resulted in commercially acceptable gonad production, the algal supplements did not improve gonad color, taste, or the proportion of marketable gonads compared to the control feed.

Summary: The study found that although submerged cages can reduce salmon lice infestation rates, current technology cannot completely solve the buoyancy-related issues with salmon, resulting in poorer growth rates and higher mortality rates in submerged cages. Therefore, when using submerged cages to improve aquaculture environments, it is crucial to ensure that fish do not encounter suboptimal conditions for growth and welfare.

Summary: This study investigated the population genetics of freshwater fish with different dispersal syndromes on the Kimberley Plateau in Western Australia. Results showed that connectivity between catchments is limited, but gene flow within catchments varies based on dispersal potential, with landscape constraints affecting this differently. Dispersal syndromes play a key role in influencing connectivity and gene flow within catchments in this rugged and fragmented landscape.

Summary: This article introduces a method for analyzing overlooked oxidizable precursors in human serum. The method involves the oxidation of precursors to perfluoroalkyl acids (PFAA) to assess undetected PFAS precursors in human serum. After optimization, the method can provide indications for high-throughput screening of undetected PFAA precursors in human serum.

Summary: This study monitored the concentrations of organochlorines (OCs) and perfluoroalkyl substances (PFASs) in eggs of the common goldeneye in central Norway over two decades. The results suggest that factors such as diet and egg laying date, as well as winter climate, are associated with the exposure to OCs in goldeneyes.

Summary: Procellariiform seabirds, such as northern fulmars, are prone to ingesting and accumulating floating plastic. A study conducted in the North Sea region found that adult fulmars had lower plastic burdens compared to younger age classes, possibly due to parental transfer of plastic to chicks. In order to investigate this mechanism, researchers examined plastic ingestion in fulmars from Kongsfjorden and found that fledglings had significantly more plastic than older fulmars. The study supported the hypothesis that fulmar chicks from Svalbard are fed high quantities of plastic by their parents. However, adverse effects of plastic on fulmars were indicated by the presence of perforations in the stomach and intestine.

Summary: This study evaluated the occurrence of microplastics in the marine atmosphere using active air sampling devices, showing their ubiquity even in remote Arctic areas. The study detected tire wear particles and clusters of polyethylene terephthalate, as well as other plastic particles in the marine atmosphere. Atmospheric transport and dispersion models suggested that microplastics are introduced into the marine atmosphere from both sea- and land-based emissions.

Summary: A comprehensive study on per- and polyfluoroalkyl substances (PFAS) in human serum samples was conducted, revealing that only a small fraction of PFAS are commonly monitored, which may lead to underestimation of human exposure. The study applied a fluorine mass balance approach and observed that total fluorine (TF) concentrations remained stable over time, while extractable organic fluorine (EOF) decreased. Furthermore, sex was found to influence the levels of unidentified EOF (UEOF) in a different way compared to target PFAS.

Summary: This study analyzed the dietary and dermal external exposure to PFOA in the European population using a PBPK model. The results showed that diet was the main contributor to internal exposure, but for some women participating in the study, personal care products also played a significant role. Therefore, further studies on exposure to PFOA and other PFAS from personal care products, especially for women, are needed.
