Abstract

The purpose of this study was to evaluate the effects of three commercial probiotics (Bio-Aqua®, Bio-Aqua pond®, and Multi Behsil 100) on the growth, nutrition, and biochemical parameters of common carp fingerlings. For this purpose, 210 common carp fingerlings (with a mean weight: 9.6±0.02 g and mean length: 12.9±0.32 cm) were randomly divided into 7 treatments (treatment 1 (control): basic diet without probiotics, treatment 2: 0.2 g of Bio-Aqua®, treatment 3: 0.1 g of Bio-Aqua®, treatment 4: 0.002 g/L of Bio-Aqua pond® dissolved in tank water, treatment 5: 0.001 g/L Bio-Aqua pond ® dissolved in tank water, treatment 6: 0.2 g of Multi Behsil 100, and treatment 7: 0.1 g of probiotic Multi Behsil 100) in triplicates, and 10 fish in each replicate. The commercial probiotics were added to the commercial diet, and the fish were fed based on body weight percentage for 60 days. Based on the results, the use of probiotics Bio-Aqua® and MultiBehsil 100, caused positive effects on the growth and nutrition parameters of common carp, although the use of 0.1 g of Bio-Aqua® per kilogram of the diet of common carp led to an improvement in growth, although, increasing the amount of this probiotic at the level of 0.2 g/kg led to negative effects on growth performance. The use of Multibehsil 100, caused positive effects on common carp. Thus, the best effect on growth performance and body composition was seen in the diet containing MultiBehsil 100 (0.1 and 0.2 g/kg of basic diet). Therefore, it can be concluded that the use of MultiBehsil 100 and Bio-Aqua® have favorable effects on common carp.
