Nano-Selenium Enriched Chitosan Particles For Fish Feed: Synthesis And Evaluation
Abstract
Background: Sustainable aquaculture depends on innovative feed strategies that enhance fish growth, health, and environmental safety. Chitosan and selenium nanoparticles have shown promise as bioactive supplements due to their antioxidant, antimicrobial, and immunostimulatory effects. This study aimed to synthesize nano-selenium-enriched chitosan particles (Cs-SeNPs) and evaluate their potential in fish feed formulation for Oreochromis niloticus (Nile tilapia).
Methods: Chitosan-selenite nanoparticles were synthesized using the ionotropic gelation method and characterized by UV–Vis spectroscopy, FTIR, SEM, XRD, and zeta potential analyses. The nanoparticles were incorporated into fish feed at varying concentrations and administered to tilapia over 45 days. Growth parameters, feed conversion ratio (FCR), protein efficiency ratio (PER), and immune responses were measured and statistically analyzed using ANOVA.
Results: The Cs-SeNPs displayed spherical morphology, high colloidal stability (zeta potential −36.4 mV), and distinct selenium incorporation confirmed by EDX. Fish fed Cs-SeNP-supplemented diets exhibited significant improvements in weight gain, specific growth rate, and protein efficiency compared to controls (p < 0.05). Enhanced lysozyme activity and phagocytic response indicated immune stimulation. The combined chitosan–selenium formulation also showed antimicrobial effects against common fish pathogens.
Conclusion: Nano-selenium-enriched chitosan particles effectively improve growth performance, feed efficiency, and immune function in Nile tilapia, demonstrating potential as a sustainable feed additive for aquaculture. These findings support further exploration of Cs-SeNPs as functional nanonutrients to enhance fish health and productivity.
