Marine environmental DNA (eDNA) is an important tool for biodiversity research and
monitoring but challenges remain in scaling surveys over large spatial areas, and
increasing the frequency of sampling in remote locations at reasonable cost. Here we
demonstrate the feasibility of sampling from commercial vessels (Mediterranean ferries)
while underway, as a strategy to facilitate replicable, systematic marine eDNA surveys in
locations that would normally be challenging and expensive for researchers to access.
Sixteen eDNA samples were collected from four fixed sampling stations, and in response
to four cetacean sightings, across three cruises undertaken along the 300 km ferry route
between Livorno (Tuscany) and Golfo Aranci (Sardinia) in the Ligurian/Tyrrhenian Seas,
June-July 2018. Using 12SrDNA and 16SrDNA metabarcoding markers, we recovered
diverse marine vertebrate Molecular Operational Taxonomic Units (MOTUs) from teleost
fish, elasmobranchs, and cetaceans. We detected s.....
