An isopod as intermediate host of cod-worm
Abstract
Ten cod (Gadus morhua), caught at 30-50 m depth in the Froan area (64°N) on the
Norwegian coast in October 1977, held an average of 53 cod-worm (Phocanema decipiens) larvae
in their muscles. Stomach contents included fish, amphipods and isopods. Of 87 isopods, 84
were identified as Idothea neglecta and from these one P. decipiens larva was recovered. The
findings suggest that I. neglecta is a significant food resource for coastal cod, and that this
isopod also is a first intermidiate host of cod-worm.
