Effects of Selenium Nanoparticles Supplemented Feed on Biochemical Indices, Growth and Survival of Yellow-Tail Seabream (Acanthopagrus latus)

The aim of this study was to evaluate the effects of feed supplemented with different levels of Selenium Nanoparticles (SeN) on growth, survival, and biochemical indices of Acanthopagrus latus. Yellow-tail seabream fish with a mean weight of ۵۲±۳ gwasfed with four experimental diets containing ۰, ۰.۵, ۱, and ۲ mg kg-۱ SeN for ۸ weeks. At the end of the experiment, the fish fed ۰.۵ mg kg-۱ SeN showed a significant improvement of weight gain compared to the control (P< ۰.۰۵). Specific growth rate, feed conversion ratio, and survival were not significantly different between treatments (P> ۰.۰۵). The lowest activity of alkaline phosphatase, alanine amino transferase, creatinine phosphokinase and cholesterol were observed in ۰.۵ mg kg-۱ SeN treatment, which was significantly lower than the control (P< ۰.۰۵). Although aspartate amino transferase, lactate dehydrogenase, triglyceride and creatinine were not significantly different among experimental treatments (P> ۰.۰۵), total protein and albumin levels were significantly increased in the ۱ and ۲ mg kg-۱ SeN treatments compared to the control group. The highest level of globulin was observed in the ۲ mg kg-۱ SeN treatment. According to the results, the addition of ۰.۵ mg kg-۱ SeN to fish feed could improve growth and biochemical parameters.
