FISH ANTHELMINTICS AND ANTHELMINTIC METHOD

摘要

It is intended to provide anthelmintics and an anthelmintic method for parasites in the field of fish farming, in particular, heterobothriums living on globefish and pseudodactylus living on eel. Namely, anthelmintics for parasites (excluding gyrodactylus) living on fishes (excluding herrings and carps such as rainbow trout) characterized by containing as the active ingredient nitroscanate or its pharmaceutically acceptable salt; and an anthelmintic method characterized by administering these anthelmintics to farmed fishes. By using these anthelmintics, parasites living on farmed fishes can be effectively exterminated. Also, infection with parasites can be prevented or treated by feeding farmed fishes with feeds containing these anthelmintics.
