Summary: This study investigated the effects of dietary bile acid supplementation on digestibility and metabolism in rainbow trout. The results showed that bile acids are a limiting factor for fat digestion in trout and that supplementation can improve fat digestibility. Additionally, dietary bile acids effectively participate in enterohepatic circulation and are absorbed in the intestine.

Summary: This research compared the effects of different levels of yellow mealworm beetle larvae meal in feed on the sensory quality of rainbow trout fillets and assessed the acceptability of this protein source to consumers. The findings showed that adding yellow mealworm beetle larvae meal did not affect the sensory quality of the trout fillets, but consumers still had some level of rejection towards this alternative protein.

Summary: The study found that the tolerance of golden pompano to soybean meal is mainly due to transcriptomic changes in lipid metabolism. Upregulation of genes related to lipid metabolism and downregulation of genes related to immunity may be the reasons for suppressing inflammatory responses and promoting growth. Genotypic variations in DEGs could potentially serve as biomarkers for early selection of fish tolerant to soybean meal or other plant-based diets.

Summary: Inflammatory bowel disease (IBD) was originally associated with industrialized nations but has now spread globally due to the popularity of ultra-processed food and lack of proper strategies to avoid foodborne microbes. Imbalance in bacteria, intestinal permeability, and dysbiosis are key factors in IBD. Using probiotics, prebiotics from algae, and a synbiotic strategy could help combat IBD by controlling pathogen proliferation and promoting beneficial bacteria growth.

Summary: Studies have shown that ancient cultures used microalgae as food for centuries. Currently, scientific reports highlight the value of microalgae's nutritional composition and their ability to accumulate polyunsaturated fatty acids. This review focuses on the use of microalgae as a source of polyunsaturated fatty acids in aquaculture feed formulations, despite their limited industrial production. It also discusses various approaches to improve microalgae production and increase the content of polyunsaturated fatty acids, and compiles studies that prove the effectiveness of microalgae-based aquafeeds for marine and freshwater species. The study also explores production kinetics and improvement strategies, as well as the main challenges in commercially producing aquafeeds using microalgae.

Summary: The chorion is an important acellular envelope in fish, protecting the developing embryo and affected by environmental and nutritional factors. The synthesis of the chorion is mediated by estradiol-17 beta hormone and its quality can impact embryo survival. Understanding the factors influencing alterations in the chorion is crucial for the aquaculture industry.

Summary: The recognition and elimination of invading pathogens are essential for host survival. Macrophages, which function similarly to vertebrate macrophages, play a crucial role in host protection in all multicellular organisms. CD14 is a pattern responsible for bacterial recognition found on the surface of macrophages. These cells store antimicrobial molecules and display polarization states similar to mammalian macrophages. The present study reports the presence of various cell markers, including CD14, in the intestinal macrophages of catfish and bonytongue, providing insights into the in vivo function of macrophages in fish.

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: Atlantic salmon fed a carbohydrate-rich diet showed suboptimal growth performance and metabolic disturbances. The study aimed to investigate the effects of graded levels of digestible carbohydrates on the distal intestine digesta microbiota in Atlantic salmon. The results demonstrated that feeding a high digestible carbohydrate diet led to negative effects on growth parameters and liver health, including increased lipid vacuolization and expression of fatty acid synthase. The composition of distal intestine digesta microbiota also changed with the carbohydrate-rich diet. Furthermore, certain lactic acid bacteria were found to be negatively correlated with hepatic steatosis and other liver health indicators. The potential use of lactic acid bacteria as probiotics to improve liver health in carnivorous fish fed a fatty liver-induced diet deserves further investigation.

Summary: The study found that the fish meal-based diet showed the best growth performance, followed by the pre-extruded Nannochloropsis diet. Feeding of unprocessed Nannochloropsis and Tetraselmis resulted in reduced enterocyte vacuolization. There was a significant effect of processing on fillet fatty acid content, intestine and liver structure, and the expression of selected genes in the liver.
