چکیده مقاله:
Super nutrients are nutrient compounds including fat dissolved vitamins, necessary minerals and growth promoters. Present research was carried out with the aim of determining super nutrients effect on some growth and biochemical indices in juvenile Acipenser baerii in International Sturgeon Research Institute during ۶ months. Blood samples obtained in days ۴۵ (stage I) and ۹۰ (stage II) and plasma provided. Some plasma biochemical an ions levels were measured in VIRO MED laboratory in Rasht. The results showed that the mean final weight, final biomass, body weight increasing (BWI), specific growth rate (SGR), condition factor condition factor (CF) and daily growth rate (ADG) showed significant difference between control group with other treatments (p<۰.۰۵). Results showed that sodium, potassium and calcium ion levels showed no significant difference in various concentrations of super nutrients during rearing period (p>۰.۰۵). Based on obtained results, super nutrients adding in diet of Acipenser baerii caused to significant difference in growth indices and improved them. Therefore, it recommended using of super nutrients in Siberian sturgeon diet.
