| Abstract |
During May and June 1988 a number of hauls were made around Helgoland with the RV "VICTOR HENSEN". A total of 377 cod (Gadus morhua L.) were investigated. They were measured, the stomach fullness estimated and the contents indentified. Crustaceans and fish were the main prey species withsome polycheates, gastropods and bivalves being taken as well. The infestation rates with the gill parasite Lernaeocera branchialis and Clavella adunca were noted, as well as spinal shortening and pseudobranchial tumours. |
