Summary: Atlantic Salmon are sensitive to soybean meal in the diet, which can cause inflammation in the distal intestine. The expression of S100I2 and S100V2 genes in the distal intestine and liver of Atlantic Salmon fed fishmeal or soybean-meal diet for 12 weeks was examined. The expression of S100V2 was significantly higher in the distal intestine of fish fed the soybean-meal diet. The histological scores confirmed distal enteritis in the soybean-meal diet group. These findings contribute to understanding the inflammatory processes associated with soy-induced distal enteritis in salmonids.

Summary: This study investigated the ability of lactic acid bacteria to prevent soybean meal-induced enteritis in Atlantic salmon. The results showed that feeding the bacteria altered the short chain fatty acids in the digesta, reduced the width of the lamina propria, and prevented enteritis.

Summary: Using functional feed ingredients, such as fucoidans from marine macroalgae, can enhance the intestinal health and immune regulation of Atlantic salmon (Salmo salar). In this trial, Atlantic salmon post-smolts were fed diets with different levels of fucoidan to alleviate low-level intestinal inflammation caused by a soya diet. The addition of fucoidan improved intestinal integrity and reduced inflammation in the hind intestine of the fish.

Summary: An unbalanced gut microbiota in fish may promote bacterial infections. However, the interactions between different bacterial groups and their effects on fish health are not well understood. This study found that pathogenic species were present in the digestive tract and gut mucosa of healthy salmon, and the dysbiosis in sick salmon may be associated with cooperative interactions between different taxonomic families of bacteria, leading to clinical symptoms.

Summary: High levels of dietary soy meals negatively affect the growth and intestinal structure of juvenile pearl gentian grouper, leading to significant increase in enteritis indices. Differential gene expression analysis shows that SBM and FSBM have different metabolic strategies, with immune diseases/systems and signal transduction pathways being significantly affected in both groups. Toll-like receptor signaling pathways play a key role in the development of enteritis induced by FSBM and SBM in pearl gentian grouper.

Summary: A meta-analysis was conducted to determine factors associated with the severity of enteritis in Atlantic salmon fed soybean meal-based diets. The results showed that fish production phase, feed type, soybean meal inclusion level, year of study, and water temperature are significantly associated with the severity of enteritis. Additionally, the severity of enteritis was found to negatively impact the specific growth rate and thermal growth coefficient of the fish.

Summary: Using soybean meal-induced enteritis as a model, this study investigated the mucosal immunity of Salmo salar and found differences in proteins like complement C5, Galectin, and Glutathione synthetase, which may play roles in immunity and detoxification. The study suggests mucosal immunoglobulins as potential biomarkers for assessing new feed ingredients and aquafeeds.

Summary: A study was conducted to evaluate the replacement effects of corn fermented protein with solubles (CFPS) on soybean meal (SBM) in the diets of Atlantic Salmon. The inclusion of CFPS as an SBM replacement showed no significant difference in growth, feed utilization, and nutrient digestibility. It resulted in increased protein content, improved lipid digestibility, enhanced immune response, and oxidative stress tolerance in the fish. CFPS had no negative effects on intestinal morphology.

Summary: This study investigated the effects of yeasts on intestinal health and transcriptomic profiles of Atlantic salmon fed SBM-based diets. The results showed that Cyberlindnera jadinii and Wickerhamomyces anomalus yeasts improved intestinal health and reduced inflammation in fish fed plant-based diets. CJ yeast controlled inflammation by promoting wound healing and taurine metabolism, while WA yeast dampened inflammation by down-regulating pathways associated with inflammatory signaling. These findings suggest that these yeasts can serve as novel high-quality protein sources for Atlantic salmon.

Summary: The study showed that soybean meal (SBM) compared to fishmeal induces down-regulation of ion binding and transport pathways, and increases levels of pro-inflammatory cytokines like tumor necrosis factor alpha (TNFα) and interferon gamma (IFNγ) at the protein level. Additionally, the inclusion of ACJ in the diets can control the pro-inflammatory profile of SBM, increasing Interleukin 10 (IL-10) levels and decreasing TNFα production, triggering an immune response similar to that of fish fed a fishmeal-based diet.

Summary: Plant-based protein sources, such as soybean, are commonly used in fish nutrition. However, soybean meal-based diets can cause gut inflammation in some fish species, leading to reduced nutrient absorption and growth rates. In this study, an Aloe vera extract was tested as a dietary additive in Atlantic salmon fed with soybean meal diet. The results showed that the addition of Aloe vera significantly reduced gut inflammation caused by soybean meal, suggesting its potential as a feed additive for aquaculture.

Summary: In this study, single-cell RNA sequencing was used to provide a high-dimensional insight into the transcriptional landscape of Atlantic salmon cells during early Infectious Salmon Anaemia Virus (ISAV) infection. The results showed a clear anti-viral response in infected cells, characterized by the upregulation of IFNA2 or IRF2. Additionally, uninfected bystander cells exhibited transcriptional differences, suggesting paracrine signaling from infected cells. This study identified potential key genes involved in the host-virus interaction, which can be targeted in future functional studies to enhance the resistance of Atlantic salmon to ISAV.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
