Abstract :
AbstractThe present study was conducted with the aim of investigating the effect of probiotics (A-max ultra and Celmanax) inoculated into the biofloc system on and water quality and the growth and feeding efficiency of common carp. In a completely random experimental design, 300 pieces of finger fish (4.09 ± 0.70 g) were distributed in fifteen 32 L tanks for 40 days. Two levels of prebiotic and one control was designed which include; 0 (T0), 0.1 and 0.2 mg/l A-max (T1 and T2), 0.1 and 0.2 mg/l Celmanax (T3 and T4) Inoculation in the culture water. The physical and chemical parameters of water were investigated in 4 stages (days 10, 20, 30 and 40 of the experiment). There was a statistical difference in the Ammonia concentration between experimental treatments, which decreased at the end of the experiment. The performance of growth and feeding of fish in biofloc treatments was significantly better than the control treatment. In general, the results showed that the use of A-max ultra and Celmanax probiotics in the biofloc environment can improve the water quality and growth performance of common carp.
