Abstract
In this research, the common carp (Cyprinus carpio) was observed in two experimental groups with a probiotic-enriched feed. Group A received a lower concentration of probiotics and Group B a higher concentration of probiotics in the feed. The fish in the Control Group (C) did not receive any probiotics in their feed. Fulton’s condition factor and body mass were monitored by five control measurements. During the five control periods, the average body mass of the common carp in the Experimental Groups A and B displayed the significantly higher values when compared with the Control Group. Fulton’s condition factor was significantly lower in the Control Group (C) than in the two experimental groups, while no statistically significant difference was detected between the Groups A and B. These results indicate that a probiotic supplementation in aquacultural feed has a positive effect on the fish growth and its overall condition.
