Summary: The study found that exposure of flatfish early life stages to ultraviolet radiation led to adverse effects such as decreased growth, impaired behavior, and inhibition of neurotransmitters and biotransformation. In the metamorphosis stage, the main observed effect was a decrease in growth. This suggests that UV exposure may have implications in later life stages.

Summary: Infectious diseases are a major cause of social and economic losses in world aquaculture, with bacterial diseases such as photobacteriosis impacting the production of Senegalese sole. This study aimed to develop an oral DNA nanovaccine for S. senegalensis juveniles against Photobacterium damselae subsp. piscicida (Phdp). The results indicate that oral vaccination with CS-TPP+pPDPimpdh NPs may be acting through non-specific immune responses as well as specific humoral and cell mediated immunity, providing a promising step towards developing an oral DNA nanovaccine against Phdp in sole.

Summary: Blood lipids and metabolites are markers that can indicate current health status as well as the risk of future diseases. In this study, plasma nuclear magnetic resonance (NMR) biomarker data from 118,461 participants in the UK Biobank were analyzed. The results showed associations between these biomarkers and the prevalence, incidence, and mortality of over 700 common diseases. The findings suggest that circulating lipids and metabolites are risk markers not only for cardiometabolic diseases but also for infectious diseases, cancers, joint disorders, and mental health outcomes, highlighting the importance of NMR-based metabolic biomarker profiling in large biobanks for public health research and translation.

Summary: The objective of this experiment was to compare the postprandial concentrations of plasma amino acids and other metabolites after the ingestion of amino acids provided either as proteins or as free amino acids and small peptides. It was found that the postprandial appearance of amino acids in the plasma was slower and lower when proteins were consumed, which may result in inefficient protein synthesis. Therefore, providing amino acids in the form of free amino acids and small peptides may be more efficient.

Summary: Live feed enrichments are commonly used in fish larvicultures to enhance growth and survival. This study investigated the effects of two commercial rotifer enrichments on bacterial communities in turbot larvae and post-larval guts during larviculture. The results showed that the enrichments had significant effects on bacterial composition in turbot larvae at 10 days after hatching (DAH), but not in the larval gut communities or bacterioplankton communities. However, a more detailed analysis revealed differences in the abundance of Vibrionales, suggesting that rotifer diets can affect the colonization of Vibrio in post-larval turbot guts.

Summary: This manuscript introduces the FEEDNETICS model, a detailed mechanistic nutrient-based model for fish farming. The model consists of a fish model, simulating fish growth and nutrient utilization at the individual level, and a farm model, upscaling the information to the population level. The model was calibrated and validated for five commercially relevant farmed fish species, and showed consistent results with a mean absolute percentage error between 11.7 and 13.8%. Several use cases were presented to demonstrate the tool's potential in experimental trial design, interpretation, and evaluating nutritional and environmental effects at the farm level. FEEDNETICS contributes to more efficient fish farming by transforming data into useful information.

Summary: This study characterizes the NLRP3 inflammasome in Atlantic salmon through structural modeling, functional transcript expression determination, and transcriptome analysis. The results suggest a similar composition and function of the NLRP3 inflammasome in Atlantic salmon and mammals. The adaptation to seawater in Atlantic salmon leads to down-regulation of inflammasome-related genes and temporary detrimental effects on the immune system.

Summary: This study aimed to understand the early innate immune response of European sea bass to T. maritimum infection. The results showed that T. maritimum induced a local immune response in the skin, gills, and posterior-intestine of the fish. This may be due to the bacteria's ability to adhere, colonize, and damage these organs. The infected fish also exhibited systemic responses, including increased neutrophils, signs of anemia, and decreased bactericidal and lysozyme activities in the plasma.
