Sealworm ( Pseudoterranova decipiens) transmission to fish trawled from Hvaler, Oslofjord, Norway

Demersal fish were sampled over 3 years to describe sealworm Pseudoterranova decipiens infection levels in relation to the size of a local colony of common seals Phoca vitulina in Hvaler, Oslofjord, Norway. More than 2000 fish were examined for worms, and five fish species were found to be infected,...

Description
Summary:Demersal fish were sampled over 3 years to describe sealworm Pseudoterranova decipiens infection levels in relation to the size of a local colony of common seals Phoca vitulina in Hvaler, Oslofjord, Norway. More than 2000 fish were examined for worms, and five fish species were found to be infected, cod Gadus morhua , four‐bearded rockling Enchelyopus cimbrius , plaice Pleuronectes platessa , long rough dab Hippoglossoides platessoides and dab Limanda limanda. A detailed analysis of worm accumulation in cod, the only infected species present in large enough numbers, shows a net decrease in worm transmission following the phocine distemper virus epizootic which killed two‐thirds of the seals in Hvaler in 1988.
