Summary: The study found that genetic introgression from escaped farmed salmon negatively impacts the survival rate of wild Atlantic salmon in a river in northern Norway, leading to a decrease in population-level genetic introgression. This suggests that there is natural selection against genetic introgression in the wild, potentially resulting in lower productivity.

Summary: Domestication can lead to changes in eye size in salmon, with individuals having smaller eyes potentially being maladapted in the wild.

Summary: Recirculating aquaculture systems (RAS) have potential benefits, such as reducing water use and improving biosecurity, but may hinder the early development of Atlantic salmon, leading to thinner epidermis, less vertebral mineralization, and altered gene expression related to bone and skin development. These differences in early development could potentially affect the robustness of salmon at later life stages.

Summary: Farm-raised Atlantic salmon escape and mate with wild ones, introducing non-native mitochondrial haplotypes to the wild population. This genetic introgression can cause long-lasting functional maladaptation in the hybrids due to the important role of mitochondrial genome and maternal inheritance. The widespread use of farm-raised salmon from non-native groups in aquaculture poses greater ecological risks to wild salmon than previously recognized.

Summary: Farmed Atlantic salmon escape and hybridize with wild Atlantic salmon, introducing non-native haplotypes into the wild population. This genetic introgression can cause functional maladaptation in the hybrids, particularly in the mitochondrial genome inherited from the mother. As the use of farmed salmon from different phylogenetic groups is widespread in aquaculture, the impact on wild salmon may be more severe than previously recognized. This study highlights the ecological risks of releasing non-native domesticated animals into the wild.

Summary: Continuous data on fish condition is crucial for real-time monitoring and management in fish farms, but obtaining it from a large net-pen environment is challenging. This study explores the potential of passive acoustic monitoring in aquaculture by investigating the influence of Atlantic salmon on the soundscape of a net-pen. The results show that Atlantic salmon alter the acoustic environment and that the acoustic fingerprint of the net-pen varies over time, reflecting the feeding status of the fish. These findings demonstrate the potential for passive acoustic monitoring in fish farms and its significance for data-driven management in aquaculture.

Summary: Each year, thousands of farmed Atlantic salmon escape and cause introgression in wild populations. Escapees that have been on the run for a longer period and successfully transitioned to a wild diet could have higher spawning success and contribute more to introgression. This study examines the escape history of farmed Atlantic salmon captured in different rivers and coastal sites, showing temporal declines in escaped vs. wild salmon and early vs. recent escapees. The proportion of early escapees varied across locations, influenced by aquaculture-management regulations and production strategies.

Summary: This study investigated the interactions between microplastics and persistent organic pollutants (POPs) in relation to Atlantic salmon farming. The results showed that microplastics can sorb POPs from aquafeeds and potentially act as vectors of these chemicals in the marine environment, thereby increasing the environmental impact of fish farming.

Summary: The research team developed a mathematical model based on the advection-diffusion equation to predict dissolved oxygen levels in fish sea cages. The model was tested in a large production unit and performed well, but may require more detailed information on fish behavior and current conditions within the cages to improve accuracy.

Summary: This study found genetic differences for fitness-related traits among wild, farm, and hybrid salmon juveniles, even over short temporal scales and under favorable environmental conditions. These differences may contribute to patterns of reduced survival in the wild for farm-mother hybrids and feral farm salmon.

Summary: Atlantic salmon Salmo salar in Europe is facing overfishing and climate change threats. Southernmost populations in northern Spain are important for conservation of original genetic diversity, endangered by massive stocking with non-native stocks. Historical genetic analysis showed high diversity and structure in southernmost salmon populations, providing valuable information for conservation programs.

Summary: Accurate monitoring of sea lice levels on salmon farms is crucial for efficient management of louse infestation. Increasing sample sizes, using appropriate treatment thresholds, and adjusting sampling intervals can improve the accuracy of abundance estimates and thus increase the frequency of effective treatments.

Summary: Through studying the pathogenesis of amoebic gill disease in Atlantic salmon, the localized and systemic immune responses of the host and parasite were identified, along with transcription factors and gene networks significantly altered in disease states. This dual transcriptomic study provides novel molecular insights into the pathology of AGD, offering alternative theories for future research and improved management strategies.
