Ascaridoid nematode infection in haddock (Melanogrammus aeglefinus) and whiting (Merlangius merlangus) in Northeast Atlantic waters
Haddock and whiting are two species of the family Gadidae that are exploited by fisheries mainly in European waters, the former being one of the most important seafood resources in Scotland (UK). The present study aimed to quantify prevalence, abundance and intensity of infection of the zoonotic par...

Haddock and whiting are two species of the family Gadidae that are exploited by fisheries mainly in European waters, the former being one of the most important seafood resources in Scotland (UK). The present study aimed to quantify prevalence, abundance and intensity of infection of the zoonotic parasite Anisakis spp. and other ascaridoid nematodes in these fish as part of a study on the risk to consumers. Fish were sourced from research trawling surveys during 2013–2015, aiming to cover a range of size-classes and different times of year. Samples were obtained from the North Sea, west coast of Scotland and the Barents Sea. Fish were stored frozen prior to separation of viscera and fillets and the use of pressing and UV visualisation to locate, identify and count Anisakis spp. and other ascaridoids in fillets (divided into 8 parts), liver and other viscera.
