Monitoraggio acustico passivo di Sciaena umbra in un allevamento di mitili del Nord Adriatico

A passive listening survey was conducted in a mussel farm, characterised by the presence of concrete structures on the bottom. The area was located adjacent to the mouth of Sile river (1 nautical mile from the coast) in the Venetian littoral zone. The monitoring proved to be successful in detecting Sciaena umbra drumming sounds. The distribution of the species was assessed on acoustic basis, suggesting that the concrete artificial structures of the area may work as reproductive FAD for breeding aggregations of Sciaena umbra.
