Summary: The transformation between iodate and iodide has attracted a lot of attention due to their dependency on oxygen concentration, which varies in the ocean. Reducing iodate to iodide is the controlling step in the reduction reaction sequence, while oxidizing iodide to iodate is the controlling step in the oxidation process. The reduction of iodate is more favorable than the reduction of nitrate at oceanic pH values, suggesting different reductants can affect the transformation.

Summary: Microorganisms contribute to the global iodine cycling through various processes such as oxidation, reduction, volatilization, and deiodination. The formation of high levels of iodide in geogenic high iodine groundwater and its microbial contribution is poorly understood. This study found the presence of putative dissimilatory iodate-reducing gene clusters in groundwater through metagenomic analyses, confirming the functional role of these genes in iodate reduction. Additionally, iron-reducing, sulfur-reducing, sulfur-oxidizing, and dehalogenating bacteria were identified, which could also contribute to iodide release and production in the groundwater.

Summary: Control of appetite and feed intake in fish larvae is still poorly understood. This study investigated the mRNA expression of key genes involved in feed intake control in Atlantic halibut larvae. The results showed differences in gene expression between fed and unfed larvae, suggesting that the mechanisms for controlling feed intake are functional to some extent. Further research is needed to fully understand the effects of PYY and CCK on feeding behavior in halibut larvae and develop inert diets to stimulate appetite and feed intake.

Summary: The hypothesis of this study was that increased growth in spring, stimulated by temperature and daylength, leads to oxidative stress and changes in antioxidant utilization in Atlantic salmon. The study found that vitamin E and vitamin C concentrations decreased in the spring and were restored in the autumn, while astaxanthin concentration remained constant during the spring and summer and increased in the autumn. Cataract and melanin spots were observed during the spring and early summer. However, the concentrations of malondialdehyde and astaxanthin did not support the hypothesis, and more data is needed to draw conclusions on the effects of oxidative stress on melanin spots.

Summary: In this study, we investigated the molecular effects of different prey types on skeletal muscle myogenesis and growth dynamics, metabolism, and antioxidant defense system in cod larval muscle. The results showed that larval growth rates were higher in copepod-fed larvae, and gene expressions related to muscle growth dynamics and ROS regulation occurred predominantly at 5, 10, and 15 mm standard length. Additionally, copepod-fed larvae exhibited more effective glucose metabolism and antioxidant defense system between 7-10 mm. Active swimming was suggested as an important factor promoting muscle growth in cod larvae during the strongest muscle hyperplasia phase (7-10 mm SL).

Summary: Farmed Atlantic salmon show an increase in antioxidant consumption during spring, but it is unclear whether this is caused by the increase in day length, temperature, or both. A simulated natural photoperiod experiment with constant temperature revealed that increasing day length led to depleted intracellular antioxidants and increased MDA levels in the liver and muscle of Atlantic salmon. The study also found a redox signaling pathway involved in the oxidative stress response and a correlation between oxidative status and physiological function in Atlantic salmon.
