Fish-Hook Ingestion in Seals (Phoca vitulina and Halichoerus grypus): The Scale of the Problem and a Non-Invasive Method for Removing Fish-Hooks
Abstract: From 1975 to 2005, the Seal Rehabilitation and Research Centre (SRRC) in Pieterburen was confronted with 12 cases of seals that had ingested a fish-hook. During the autopsy on ten seals, perforations were found in the oesophagus, stomach, and intestines. Two seals survived the ingestion of a fish-hook by being fed cotton wool, which prevented a perforation. Most hooks were identified as hooks used in fisheries around wrecked vessels to catch cod. Fishermen are therefore advised to take preventive measures.
