Preliminary observations on abnormal abundance of Cetorhinus maximus (Gunnerus, 1765) in the Central and Northern Adriatic Sea

During 2000 and in the first months of 2001, numerous records of Cetorhinus maximus (Gunnerus, 1765) have been collected in the Middle and Northern Adriatic Sea, along the Italian, Croatian and Slovenian coasts. The collected records include: 1) sightings of single specimen and small groups ; 2) reports of some accidental captures. Some considerations, on the apparent migratory movement in the Adriatic, the comparison between actual and historical data, the comparison with data concerning the Tyrrhenian Sea, are presented. Some hypotheses about the causes of the unusual basking shark abundance in the area are presented, also.
