Sealworm ( Pseudoterranova decipiens ) infection in the benthic cottid ( Taurulus bubalis ) in relation to population increase of harbour seal ( Phoca vitulina ) in Skagerrak, Sweden
In Koster archipelago (northern Skagerrak, Sweden) the harbour seal population increased from approximately 350 to more than 1000 individuals between 1988 and 1998. During the same period, sealworm (Pseudoterranova decipiens) abundance in the most heavily infected fish species, bullrout (Myoxocepahu...
