Summary: Reducing dependence on fishmeal is a major challenge for sustainable aquaculture, and insects are one of the most promising alternatives. This study found that yellow mealworm is the best alternative for rainbow trout, possibly due to changes in protein utilization and intestinal histology. Insect meals also showed potential as functional ingredients in preventing tissue damage.

Summary: This study assessed the effects of dietary insect meal from Hermetia illucens larvae on the gut microbial community of rainbow trout. The inclusion of insect meal in the diet led to an increase in beneficial bacteria and a reduction of pathogenic bacteria, shaping the metabolic activity of the trout gut microbiota. Insect meal from H. illucens is a promising protein source for trout nutrition, with potential to improve fish health by modulating the gut microbial community.

Summary: This study investigated the effects of fully replacing fishmeal with Tenebrio molitor larvae meal on the gut and skin microbiota of rainbow trout. The data showed slight changes in the microbiota after total replacement with insect meal, with no major effects on bacterial species richness and diversity. The study suggests that Tenebrio molitor larvae meal could be a viable alternative to fishmeal in aquafeeds.

Summary: The study found that Chlorella meal can be a potential alternative to fishmeal in rainbow trout feed. Diets based on Chlorella meal improved growth performance, intestinal health, and had effects on amino acid and fatty acid metabolism. However, diets combining Chlorella meal with black soldier fly larval meal did not improve growth performance but had anti-inflammatory effects and improved bacterial diversity.

Summary: In the study of farmed rainbow trout samples in Rize, Turkey, two novel Flavobacterium species were discovered, and their taxonomic positions were confirmed through 16S rRNA gene sequence analysis. A polyphasic taxonomy approach was employed to establish the novelty of these strains, leading to the proposal of Flavobacterium bernardetii sp. nov. The isolates were found to have unique genomic and phenotypic characteristics, indicating a possible correlation with mortality in rainbow trout.

Summary: Environmental stressors can disrupt the microbiota-host relationship and cause loss of function. In this study, the effects of Aeromonas salmonicida infection on the taxonomic composition and structure of the fish microbiota were assessed. The results indicate that the infection can lead to dysbiosis and an increase in opportunistic pathogens, and the findings may contribute to the development of non-invasive disease prevention techniques in aquaculture.

Summary: Aquaculture plays a significant role in global food security, and its future development relies on sustainable aquafeed production. Fish meal is unsustainable and not eco-friendly, but it is still widely used in aquafeed production. Brewer's spent yeast (BSY) is a potential alternative protein source in aquafeeds, as it has high protein content, is cheaper than fish meal, and possesses beneficial properties. This review focuses on the utility of BSY biomass in aquafeed production.

Summary: Aquaculture is becoming increasingly important for global food supply, but its growth is constrained by environmental impacts. Spain, as a major supplier, accounts for 25% of aquaculture production in the European Union. This study used Life Cycle Assessment (LCA) to evaluate the production of rainbow trout in a medium-sized plant in Galicia, Spain. The results showed that aquafeed had a significant impact on most categories, and farm operation was responsible for freshwater eutrophication.

Summary: Accurate feed evaluation is crucial for feed formulation in aquaculture. This study tested a net energy (NE) evaluation method in predicting growth performance of rainbow trout feeds, showing that replacing fat with carbohydrates reduced energy utilization for growth, especially at high carbohydrate levels. The NE approach using linear efficiencies of digestible macronutrients demonstrated improved prediction precision of growth rate compared to the digestible energy (DE) approach. However, assuming a curvilinear effect of carbohydrates did not lead to an improved prediction of growth rate in this study.

Summary: Emulsions with crystalline dispersed phase are commonly used in life sciences, but they are often unstable and their rheological behavior can change. These changes are possibly due to shape transformations of the crystallized droplets, which depend on the cooling rate during production and storage temperature.

Summary: The influence of the conformation of sugar beet pectin on its interfacial and emulsifying properties was investigated. The results showed that the compactness of the conformation affects the reduction rate of interfacial tension, adsorbed mass, and layer thickness. The required concentration of pectin for stabilizing oil droplets at specific pH conditions is also affected by the conformation.

Summary: The stability of double emulsions depends on the rapid formation of viscoelastic interfaces between water and oil phases. Cooperative adsorption of hydrophilic and lipophilic surfactants and its impact on the properties of water/oil/water interfacial films were studied to replace empirical methodologies in designing double emulsion systems. Experiments and simulations were conducted to investigate surfactant distribution, stability against coalescence, and surfactant conformation at the interface. It was found that the competitive adsorption of sodium dodecyl sulfate and lipophilic surfactant resulted in improved encapsulation efficiency, interface elasticity, and resistance against coalescence.

Summary: There are many applications for crystalline triglyceride-in-water dispersions in the life sciences and pharmaceutical industries. The particle morphology and size distribution are the main factors influencing the properties of these dispersions. In this study, the influence of the dispersed-phase composition on the crystallization and melting behavior of these systems was investigated. Different particle morphologies were obtained by varying the dispersed-phase composition, and smaller droplets were obtained after melting. The self-emulsification and coalescence events were influenced by the melting range of the fat and the surfactant concentration.

Summary: Understanding the generation, extent, and location of thermomechanical stress during small-scale melt-extrusion is crucial for determining the stability of protein particles. Experimental and numerical approaches were utilized to evaluate the impact of extrusion process design on protein stability. The results showed that the ram extruder is more favorable for producing stable protein-loaded extrudates in small scale, compared to the twin-screw extruder.

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.
