These considered to have been introduced museum late 1980s along with wild transported live natural waters Hokkaido. Adult manually removed forceps once or twice a year chars, but such infrequent practices not effective eliminate markewitschi, which was thus again 2020. contrast, completely eliminated by stopping rearing an infected population this parasite is host-specific.
