Summary: This study analyzed the effects of different feeds on the lipid composition of juvenile Oncorhynchus mykiss muscle and found that the inclusion of Brassica napus oil significantly increased certain lipid levels, while Durvillaea antarctica meal had a less significant impact on lipid variation.

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: Including black soldier fly prepupae meal in trout diets did not impact most nutritional and growth parameters of trout compared to the control; however, the coefficient of fatness increased, weight gain decreased, and fatty acid profiles of fillets were altered.

Summary: In this study, the anesthetic effects of lavender and laurel essential oils on rainbow trout were investigated. It was found that specific concentrations of these oils showed ideal anesthetic effects with negligible histopathological effects on the fish tissues.

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: Two yellow-pigmented isolates, F-60(T) and F-392, were isolated from the internal organs of a healthy rainbow trout. Based on 16S rRNA gene sequence analysis, these isolates were identified as a novel species within the genus Flavobacterium, named Flavobacterium muglaense sp. nov. with F-60(T) as the type strain.

Summary: This study did not find a relationship between farm or transformation process locations and antibiotic resistance patterns of Pseudomonas isolates. The majority of isolates belonged to the Pseudomonas fluorescens group, with some showing multi-drug resistance.

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: Despite vaccination, outbreaks of vibriosis still occur in sea-reared rainbow trout in Denmark. This study found that the antigenic variability within V. anguillarum serotype O2a strains can affect the antibody response and protection induced by bacterin-based vaccines. The study also found that the antibody reactivity classification of strains is correlated with genotyping and variability in the accessory genome.

Summary: This study aimed to evaluate the hygienic-sanitary status of fresh-farmed rainbow trout fillets produced in a local fish farm in Andalusia, Spain. The results showed potential transmission of microbial contamination and suggested the implementation of control measures in fish farm facilities to extend the shelf-life of farmed fishery products.

Summary: To ensure the sustainability of aquaculture, it is necessary to change the diet of carnivorous fish like rainbow trout from a fish-based diet to one with plant-based ingredients. However, there is a problem with the decrease in growth performance of fish fed with a 100% plant-based diet. In this study, high levels of digestible carbohydrates were incorporated in a 100% plant-based diet to improve protein utilization and reduce nitrogen waste. The study measured the changes in intestinal microbiota, Short-Chain Fatty Acid (SCFA) levels, and metabolic responses in the liver, and found that dietary carbohydrates had significant effects on the diversity and abundance of certain bacteria, as well as gene expression in the liver.

Summary: Climate change and overexploitation of natural resources drive the need for innovative and sustainable food production, and aquaponics, a combination of recirculation aquaculture systems (RAS) and hydroponics, could be a promising solution. Rainbow trout, a major freshwater fish species, has the potential to be commercially developed in aquaponics. Aquaponic systems offer lower freshwater demands, greater land use efficiency, and decreased environmental impact, while providing higher fish productivity. Intensive farming of rainbow trout in aquaponic systems can be controlled using digital monitoring of the system parameters, mitigating the obstacles caused by extreme temperature fluctuations.

Summary: Chemical compounds like formalin are commonly used to prevent fungal infections and treat external parasites in fish eggs and hatchery-reared fish. However, formalin exposure can lead to mortality, depending on the concentration used and rearing conditions. Different strains of rainbow trout also exhibit varying sensitivity to formalin. Therefore, it is important to consider formalin concentration, rearing conditions, and strain differences before implementing large-scale treatments.

Summary: In recent years, the application of new molecular techniques has brought new opportunities for genetic and genomic studies of fishes, with genomic selection being widely used in the aquaculture sector. This method is particularly relevant for traits of high economic value and has the potential to substantially improve breeding programs and transform fish breeding systems.

Summary: Salmonid fish, particularly brown trout, are widely used as ecological and research models in the conservation genetics and genomics field. The Salmo trutta complex, which consists of multiple geographic forms, is found in Europe. Seven major evolutionary lineages have been identified based on mitochondrial DNA analysis. Populations in Italy and surrounding areas show high genetic diversity, and some lineages are protected due to their threatened status. Recent studies using traditional and next-generation sequencing techniques have revealed genetic differences between populations in different regions.
