According to the new EU Reg 2019/6 Receptal ® Ireland MSD (Distributor AGRIHEALTH) can be administered with a waiting time of 25-degree days (eg at 160C 36 h). The dosage is 1-5 µg/kg body weight with a priming dosage of 10% and a resolving dosage of 90% after 12 hours according to the prescription by the responsible veterinarian. 1 µg/kg is sufficient if the fish is in its natural seasonal cycle. The management of the temperature regime must be set to fit to the expected waiting time. Important: the fish is injected while swimming at lowered water level in order to avoid handling stress.
