Summary: The study found that Atlantic cod in the western Gulf of Maine are managed as a single stock, but actually consist of two spawning groups (spring and winter) with significant genetic differentiation. By selecting specific SNP panels, researchers can effectively differentiate between different spawning groups and genders.

Summary: Climate change impacts fish populations and their dynamics, and it is crucial to consider non-stationary vital rates in fishery stock assessment and management. This study focused on the effects of non-stationary natural mortality on the stock assessment of Atlantic cod in the Gulf of Maine. The results showed that adopting non-stationary mortality rates improved the accuracy of stock assessment compared to the commonly used stationary assumption.

Summary: The fine-scale behavioural responses of Atlantic cod to airgun exposure over an extended period were investigated using an acoustic telemetry positioning system on a spawning ground in Norway. The results suggest that relatively distant seismic surveys do not substantially alter cod behaviour during the spawning period at received sound exposure levels varying between 115 and 145 dB re 1 mu Pa(2)s over a 5-d period.

Summary: Seafood is perishable and preservation techniques like freezing and thawing can help maintain freshness, but have limitations. Differences exist in preservation techniques among commercial sectors. Utilizing the concept of global value chains can improve seafood quality through freezing and thawing processes.

Summary: This study examines the impact of ignoring biological stock structure in habitat modeling using juvenile Atlantic cod as an example. The results show that neglecting to consider stock structure can lead to inaccurate detection of spatially explicit habitat relationships, hindering the recovery of collapsed stocks such as Atlantic cod.

Summary: Larval cod require live prey for growth and survival, and prey concentration and feeding frequency are important factors. Water exchange rates and current also influence prey resident time and larval behavior. High water current induces stress and cortisol levels, while an intermediate rearing protocol leads to better growth and survival.

Summary: Nassau grouper, once an important fishery species in the Caribbean, is now critically endangered due to population collapse caused by overfishing of their spawning aggregations. Protecting this vulnerable period is crucial for their survival.

Summary: This study found that electron beam irradiation can effectively inactivate SARS-CoV-2 and improve the quality indicators of Atlantic cod, but it also has some effects on the hardness, chewiness, and color of the fish.

Summary: Until recently, it was believed that MHC genes and their associated immune components had been conserved since their evolutionary emergence. However, sequencing of the Atlantic cod genome revealed a loss of MHC class II genes and an extreme expansion of MHC class I genes. These findings suggest a possible functional shift from MHC class II to MHC class I.

Summary: A study found two sympatric ecotypes of Atlantic cod in the Skagerrak and Kattegat region, indicating different adaptations to the environment. This highlights the importance of considering locally adapted ecotypes for fisheries management.

Summary: The tagging-induced mortality experiments on Baltic cod showed that tagging did not have a significant effect on mortality, with mortality mainly attributed to capture and handling procedures. There was a negative relationship between fish length and mortality, and significant variations in mortality were observed between different tagging sites.

Summary: In this study, polyethylene (PE) microplastics were added to Atlantic cod feeds at 1%, either in their original form or spiked with PCB-126. After a 4-week period, cod fed spiked PE showed a higher concentration of PCB-126 in liver and muscle samples compared to control and fish ingesting virgin PE. The expression of hepatic cyp1a was higher in cod fed spiked PE, indicating an accumulation of PCB-126 in the liver. Moreover, both spiked PE and virgin PE had an effect on the skin, suggesting a reduced skin barrier in fish fed a diet containing PE.

Summary: Understanding individual growth in commercially exploited fish populations is crucial for stock assessment and fisheries management. Traditional methods for estimating fish growth have limitations, while bioenergetic modeling provides an alternative approach that can explain the effects of environmental changes on growth. A bioenergetic model for Western Baltic cod was developed, which successfully reproduced seasonal growth patterns and highlighted the potential negative impact of climate change on cod growth.

Summary: This study analyzed fisheries data and scientific surveys of windowpane flounder in the northwest Atlantic, finding that temporary closed areas were not located where the highest densities of the fish occurred, but where the highest rates of discards were recorded, indicating alignment between fishermen's observations and scientific findings.
