A red-tailed catfish (Phractocephalus hemiolioplerus) referred to Aquatic Animal Health Department, Faculty of Veterinary Medicine, University of Tehran for showing lethargy, bottom sitting, extension of abdomen and sever abdominal injuries. Its abdomen was swollen and the bulk of the foreign bodies were easily palpated. The heaviness of foreign bodies had made swimming and buoyancy difficult for fish. Several radiographic images were taken after anaesthetizing the catfish with 10% carvacrol, 2 drops in 1 liter of water. Radiographs revealed some stones with their size, number and location. Stones were removed non-surgically through the large oral cavity using suitable forceps. Totally 16 stones and 2 shells were removed from the stomach of the fish. The catfish was then returned to the water where normal swimming and buoyancy was restored.
