Ulcers associated with larval Anisakis simplex B (Nematoda: Ascaridoidea) in the forestomach of harbour porpoises Phocoena phocoena (L.)
Anisakis simplex B larvae and adults occurred in the forestomach of 7 of 10 Phocoena phocoena found drowned in cod nets in the winters (November–January) of 1977–1978, 1980–1981, 1981–1982, and 1983–1984, along the Scottish east coast. A cluster of third- and fourth-stage larvae was found in one lar...
