The lesser-spotted dogfish ( scyliorhinus canicula ) : parasites and scavenger habits

The occurrence of parasites in the digestive tract of the lesser-spotted dogfish (Scyliorhinus canicula) caught in the north western Mediterranean was analysed and the results compared with infestation levels in samples of the same species caught in the Atlantic (off the south west coast of Ireland). The relationships between parasite levels and the scavenger habits of the lesser-spotted dogfish are reviewed. The importance of adapting sanitary controls when working with lesser-spotted dogfish on board commercial fishing vessels is emphasised. It is suggested that protocols be adopted so as to prevent increased parasite loading in the lesser-spotted dogfish.
