Summary: The immune system of Atlantic cod and haddock differs from other vertebrates in antigen presentation processes, with a lack of essential genes for exogenous antigen presentation but an expanded MHC-I gene repertoire. This suggests their reliance on cross-presentation of exogenous antigens to combat extracellular threats.

Summary: This study investigates the impacts of tailings from a calcium carbonate processing plant on early live stages of haddock and Atlantic cod. Results show that mineral particles adhere to fish eggs, affecting egg buoyancy, survival, and development. Tailing exposure induced early hatching, reduced survival, and caused malformations in larvae, particularly in cod.

Summary: The study estimated the numbers and instantaneous mortality rate Z of haddock and cod larvae in a hatchery from 0 to 50 days post hatch using direct and non-destructive methods. Results showed that the mortality rate of haddock larvae was higher than that of cod larvae, with variations observed. The technique proved useful for estimating Z in hatchery mesocosms and examining the causes and timing of larval mortality.

Summary: Temperature fluctuations affect the distribution of marine fish species, leading to geographical expansion or retraction. This study examines the changes in geographical distribution of Icelandic haddock over a 38-year period. Haddock density and condition are influenced by temperature, density-dependent factors, and food availability, with significant differences between the north and south areas.

Summary: The study successfully developed a novel one-step triplex high-resolution melting (HRM) analysis for rapid authentication of commonly found Gadiformes species on the Chinese market. By targeting mitochondrial genes, this technique showed high specificity and discrimination capabilities. Validation on commercial products demonstrated the suitability of this method for rapid identification of Gadiformes species.

Summary: The study revealed that Atlantic halibut larvae efficiently incorporate dietary fatty acids through monoacylglycerols, but their ability to absorb and incorporate fatty acids when provided as free fatty acids or bound to triglycerides or phospholipids seems to be low. Esterification into phospholipids is the main metabolic fate for dietary long-chain polyunsaturated fatty acids, and the larvae have a capacity for metabolizing dietary fatty acids through elongation and desaturation processes. However, the larvae showed a reduced ability to biosynthesize EPA and DHA, highlighting the importance of adequate dietary supply for proper larval development.

Summary: This study tracked the oocyte development of north-east Arctic haddock over 9 months and found that skipping, where adults terminate their upcoming reproductive cycle, is common in this species. The study also discovered an extended and early appearance of cortical alveoli oocytes (CAO) in this species, which affects its reproductive cycle.

Summary: Ecological patterns and processes occur at various spatial and temporal scales. Determining the appropriate scale(s) for data collection and analysis depends on the phenomena being studied. Avoiding the risk of presenting results that are influenced by measurement scale is important to understand actual ecological processes.

Summary: This study found that density-dependence is the main factor influencing haddock growth changes, with the impact of temperature varying by season. Although of lesser model importance, annual winter salinity and phytoplankton bloom magnitude (lagged by one year) also contributed to growth model fits.

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: 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: 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.
