Immature specimens of Opechona sp. are described from the stomach, pyloric caeca and intestine of larval and O‐group haddock, Melanogrammus aeglefinus (L.), taken in the northern North Sea and to the west of Scotland. This appears to be a new host record and possible sources of infection are discussed, together with the occurrence of this normally intestinal parasite in the stomach. It is suggested that these infections may be worth taking into account when considering possible factors contributing to mortalities of haddock and other teleost larvae.
