A feeding trial was conducted to assess the impacts of dietary astaxanthin from wall-broken Haematococcus pluvialis (WBHPA) on growth performance, antioxidant status, immune response, and intestinal health rainbow trout (Oncorhynchus mykiss). Six experimental diets were formulated with various concentrations WBHPA, ranging 0 8.4 g/kg (containing 125 mg/kg astaxanthin). Each diet fed triplicate groups (mean initial weight 561 g) twice daily for 9 consecutive weeks. The survival rate feed intake fish exhibited no significant differences among (P > 0.05). Similarly, inclusion 25 100 did not significantly affect gain coefficient 0.05), but excessive (125 mg/kg) slightly depressed these parameters < Dietary 50 increased activities digestion absorption enzymes (lipase, creatine kinase, alkaline phosphatase), while 75 improved response fish. Furthermore, regardless level (25 mg/kg), supplementation strengthened mucosal barrier function activity, thereby promoting development. Conclusively, WBHPA recommended be included in trout.

Aquafeed's contamination by microplastics can pose a risk to fish health and quality since they be absorbed the gastrointestinal tract translocate different tissues. The liver acts as retaining organ with consequent triggering of oxidative stress response. present study aimed combine use natural astaxanthin natural-based microcapsules counteract these negative side effects. European seabass juveniles were fed diets containing commercially available fluorescent microplastic microbeads (1-5 μm; 50 mg/kg feed) alone or combined microencapsulated (AX) (7 g/kg feed; tested for half whole feeding trial-30 60 days, respectively). Fish from dietary treatments did not evidence variations in survival growth performance show pathological alterations at intestinal level. However, level translocation liver, leading, when provided solely,

Microplastic (MP) contamination in aquafeed poses a significant risk to fish health and safety. This study evaluated the effectiveness of microencapsulated natural antioxidant, astaxanthin (AX), mitigating adverse effects dietary MPs rainbow trout fry. The microcapsules were composed an organic wall matrix designed preserve AX while limiting MP absorption intestine. During 60-day feeding trial, fed diets containing amino formaldehyde polymer fluorescent microbeads (1-5 µm; 50 mg/kg), either alone or combination with AX. localization tissues was assessed via confocal microscopy, quantification performed following chemical tissue digestion. Fish welfare using histological molecular analyses. No on growth gut morphology observed across experimental groups. However, mainly translocated liver, where they induced oxidative stress, as evidenced by upregulation sod1, sod2, cat gene expression. inclusion significantly mitigated stress response, facilitated coagulation gut, reducing intestinal absorption. These findings highlight potential antioxidants counteract MP-induced reduce bioavailability aquaculture species, contributing improved product quality.

The presence of multiple conjugated double bonds and chiral carbon atoms endows astaxanthin with geometric optical isomers, these isomers widely exist in biological sources, food processing, vivo absorption. However, there remains no systematic summary regarding isomerization methods analytic techniques. To address this need, Review focuses on a comprehensive analysis Z-isomerization astaxanthin, including solvent system, catalyst, heat treatment. Comparatively, high-efficiency health-friendly are more conducive to put into practical use, such as food-grade solvents food-component catalysts. In addition, we outline the recent advances techniques well structural characteristics reflected by various (e.g., HPLC, NMR, FTIR, RS). Furthermore, summarized related research safety evaluation isomers. Finally, future trends barriers Z-transformation also discussed.

Astaxanthin, a xanthophyll carotenoid, exhibits potent biological functions, including antioxidant, immune regulation, growth promotion, improved reproductive capacity, and enhancement of the body color aquatic animals. In recent years, with rapid development aquaculture industry, application astaxanthin in has garnered increasing attention. Studies have demonstrated that significantly enhances antioxidant capacity animals, reduces oxidative damage, regulates expression immune-related genes, thereby improving immunity disease resistance. Moreover, promotes performance, particularly high-value species, where it also serves as natural pigment to increase market competitiveness. However, low bioavailability high production costs remain major constraints its widespread use aquaculture. To address these limitations, various strategies—such microencapsulation, liposomal delivery, nanotechnology—have been explored improve stability water solubility. Additionally, expanding sources optimizing processes are effective approaches reducing costs. This review summarizes advances research within aquaculture, highlights multifunctional roles promoting health efficiency discusses current challenges future directions.

In this study, we investigated the body characteristics, carotenoid composition, and nutritional quality of Eriocheir sinensis with different hepatopancreas redness (a*). We distributed crabs into two groups based on a* values compared their chroma, protein, lipid, total sugar, amino acid, fatty acid content via paired t-test. The results revealed that relationships between crab are sex specific. female crabs, differences in characteristics were evident mainly hepatopancreases ovaries. redder hepatopancreases, zeaxanthin β-carotene increased, levels C22:6n3 C20:5n3 decreased (p < 0.05). ovaries, astaxanthin, canthaxanthin, β-carotene, umami, sweet acids lower male there positive content. leucine, arginine, umami muscles unsaturated n-6 polyunsaturated testicles increased increasing Therefore, hepatopancreas, higher crabs.
