This paper proposes a method of oral administration of drugs to predatory fish species using the example of common pike perch. The study was carried out on 26 specimens of pike perch breeders who received various injuries as a result of spawning, as a result of which ulcerative lesions appeared on the surface of the fish body with the threat of secondary infection. The behavioral responses of the fish were suppressed. To improve the condition of manufacturers, we used: therapeutic baths ("Antibacterial 500"); feeding with a probiotic preparation (bacteria Bacillus subtilis strain DSM 32424); treatment of external damage (povidone-iodine). The complex application of these drugs has shown a positive therapeutic effect in the recovery of pike perch breeders. The survival rate was 80.8%.
