One of the main challenges in aquaculture is constant search for sustainable alternative feed ingredients that can successfully replace fishmeal (FM) without any negative effects on fish growth and health. The goal present study was to develop a toolbox rapidly anticipating dynamics following introduction new feed; nonlethal, biochemical, molecular markers provide insights into physiological changes fish. A nutritional challenge by feeding conventional rich FM protein (FM diet) versus an experimental plant (PP) low inclusion (PP diet), 20 different families gilthead sea bream ( Sparus aurata ) performed. Fifteen 30 days after initiation challenge, transcriptional response seabream erythrocytes along with classical hematological biochemical were compared. Zootechnical, transcriptome data from each family under dietary treatments combined classification model identify variables predict rate at end 14‐month farming period (July 2018–September 2019). highly accurate produced > 80%) based combination seven (five two markers) high potential separating faster slower growing as early feeding.

Serum proteins are essential for maintaining osmotic pressure, regulating pH, transporting metabolites, and supporting immune responses. Studying the effects of plant-based diets on these is crucial to understanding their impact fish health function. Methods: This study was conducted in a recirculation system, with rainbow trout distributed across nine tanks fed three diets: fishmeal (control), medium plant meal (MPM; 40% replacement), high (HPM; 80% replacement). Plasma protein plasma glucose levels were measured at initial final stages, under both fasting (24 h after fast) postprandial (6 fed) conditions, assess dietary impacts. Additionally, hepatosomatic index (HSI) calculated end experiment evaluate potential liver adaptations diets. Results: The similar all groups. However, by treatment, fishmeal-fed group showed significantly higher total globulin levels, while albumin remained consistent diet types. A significant interaction between sampling time treatment reduced clarity levels. Furthermore, HSI lower (HPM) compared (MPM) groups, suggesting metabolic adaptation response Conclusions: Replacing reduces concentrations but leaves unaffected, alongside reductions low growth different highlights stress, emphasizing need further research optimize sustainable aquaculture feeds performance.

The aim of this study was to evaluate the utilization fairy shrimp (Branchinella thailandensis) meal in diets flowerhorn cichlids, on their growth, skin coloration, carotenoid content, antioxidant activity, and innate immunity. fish were fed incorporated with at 0% (control; FS0), 10% (FS10), 20% (FS20), 30% (FS30) for 60 days. results showed that growth performance chemical composition not significantly different among treatments (p > 0.05), whereas diet represented enhanced particularly terms redness (a*) dominant wavelength (H°ab). highest level enzymes non-specific immune such as SOD lysozyme observed FS30 diet. Meanwhile, increasing reduced liver function markers (ALT AST), decreased lipid peroxidation. These findings suggest serves a valuable dietary ingredient enhancing pigmentation, boosting defense, stimulating responses cichlids. Moreover, economic evaluation using an ornamental demonstrates promising investment potential, supporting its application commercial aquaculture.

The use of fish meal/oil in carnivorous feeds remains a concern for the environmental sustainability aquaculture. In this study, we investigated impact an innovative diet designed to be cost‐effective and environmentally sustainable (i.e., 60% replacement meal by blend plant, yeast [ Saccharomyces cerevisiae ], krill feed ingredients) on growth, health, welfare gilthead seabream ( Sparus aurata ). Over 135‐day experiment, were fed either or commercial (control), various parameters evaluated, namely growth performance, levels physiological blood related stress, immunity, welfare, as well swimming activity, serving proxy energy expenditure. Results revealed that enhanced compared control diet. Hematological biochemical indicators did not highlight any impaired condition while higher Immunoglobulin M measured plasma diet, potentially suggesting enhancement humoral immunity. However, accelerometer tags data exhibited overall expenditure, which was consistent with greater prealbumin plasma. conclusion, metabolism might compensated diet’s content, may boost immunity hence help develop better adaptation rearing environment, including its viral bacterial load, ensuring growth. Longer term investigations, measurements additional parameters, are required validate these promising preliminary outcomes.
