Effects of selenium nanoparticles on growth performance, hematological, serum biochemical parameters, and antioxidant status in fish

Usage of nanoparticle forms of trace elements in fish diets has attracted considerable attention in recent years due to the beneficial effect on fish health. Selenium nanoparticles (SeNPs) are particles with dimensions between 1 and 100 nm obtained by reducing selenate or selenite by physical, chemical, or green synthesis methods. SeNPs have high biological activity, catalytic activity, particle distribution, and high bioavailability compared to other selenium sources (sodium selenite, selenomethionine, methylselenocysteine etc.) due to their large surface area/volume ratio. SeNPs have been used as food additives and therapeutic agents because of their role in thyroid hormone metabolism, regulation of the immune system and biologically important enzymes, especially antioxidant enzymes. Many studies have been conducted to observe the different effects including growth, haematological and biochemical, immunological, antioxidant, toxicity of SeNPs in various fish. Research have shown that SeNPs especially improves growth performance parameters and antioxidant status in fish under various stress factors including hypoxia, lead toxicity, malathion, high temperature (34 degrees C), Aeromonas hydrophila, Streptococcus iniae, Aeromonas veronii biovar sobria, high-fat diet or compared to other selenium sources. This review is an update of information on effects of SeNPs in growth performance, hematological and serum biochemical parameters as well as stimulation of antioxidant status in fish in the presence or absence of different stress conditions.
