A 63-day experiment was conducted to determine the effects of nanoselenium formulated diets on growth performance, nutrient utilization and haematological profile of Clarias gariepinus . Fish were acclimatized for 14 days, 10 fish each were randomly introduced into different troughs. Feed supplemented with nanoselenium at 2 mg/kg, 4 mg/kg and the control without nanoselenium were fed to group of fish each in triplicate. The feed intake, weight gain, food conversion ratio (FCR), specific growth rate (SGR), protein efficiency ratio (PER) and survival rate (SR) were determined, also the haematological profile of Clarias gariepinus fed were analyzed. There were significant increase (p<0.05) in the weight gain of fish fed 2 mg/kg of nanoselenium as compared with those fed 4 mg/kg of nanoselenium and the control. Similarly, PER and SR were significantly higher (p<0.05) in 2 mg/kg when compared with other formulated diets. The FCR of fish fed 2 mg/kg was significantly lower compared with 4 mg/kg nanoselenium formulated diets. WBC, RBC, haemoglobin, and haematocrit significantly increased in fish fed 2 mg/kg of nanoselenium as compared with those fed 4 mg/kg nanoselenium and the control group while there was variation in the values of other haematological parameters such as platelets, MCV, MCH and MPV. The research indicated that dietary inclusion of nanoselenium at 2 mg/kg may enhance better growth performance and nutrient utilization of Clarias gariepinus.
