Résumé

Data on the chondrichthyes occurring in the Gulf of Naples were reviewed by taking into account historical and present literature, as well as specimens preserved in the main naturalistic museums and other scientific institutions. Monitoring of landings and interviews with fishermen operating in the fishing ports of Ischia, Procida, Pozzuoli and Mergellina, were also carried out. The presence of 53 species of Chondrichthyes (27 sharks, 25 batoids, one chimaera) was attested in the Gulf of Naples. They represent 76% of the chondrichthyans known in the Italian waters and 63% of Mediterranean species. The rough ray Raja radula is documented for the first time in the study area. Two sharks, Squatina oculata and Carcharhinus brevipinna, and one skate Raja brachyura were added to the Gulf of Naples ichthyofauna, but need further confirmation. With regards to sawfishes (Pristidae), we found some old museum material and archive data supporting the presence of a Pristis species in this area.
