Abstract Batches of 10 Anisakis larvae from Greenland salmon ( Salmo salar ) were labelled with radioiodcin and fed to 10 haddock ( Melanogrammus aegiefimis ). Similar batches of larvae from herring ( Clupea harengus ) were fed to 8 whiting ( Merlangius merlangus ). At post-mortem from 15 to 190 hours after infection, 0 to 6 larvae were recovered from whiting (over-all recovery rate 18.8%) and 0 to 4 larvae were recovered from haddock (over-all recovery rate 27%). Larvae penetrated the wall of the stomach or of a pyloric caecum. They were first seen in the body-cavity 24 hours after infection and a delicate capsule was present around some of them by 34 hours. Most larvae were recovered from the body-cavity but, in haddock, two had penetrated the epaxial musculature.
