Ballast water transferred by vessels is recognized by the United Nations as a prominent vector for transfer of harmful aquatic organisms and pathogens across natural barriers.
The volume of Ballast Water discharged in the Adriatic Sea ports is above 10 million tons per year.
In the whole Adriatic region 190 non-indigenous species were registred by Zenetos et al. (2010).
The BALMAS project integrates all necessary activities to enable a long-term, environmentally efficient and financially and maritime transport sustainable implementation of ballast water management measures in the Adriatic.
Within BALMAS we will establish a common cross-border system linking all Adriatic research, experts and national responsible authorities in order to avoid the unwanted risks to the environment and humans from the transfer of harmful aquatic organisms and pathogens through the control and management of ships’ ballast waters and sediments.
Between the end of October and the first week of November, the seasonal water and sediment sampling was carried on in the port of Ancona by CNR-ISMAR.
Salinity, temperature, oxygen and water samples for chemical analyses (chlorophyll-a and nutrients) were collected from the selected stations inside and outside the port. From the same sampling sites the surface water and sediment samples were collected to assess the presence of pathogens.
Figure 1: Box-corer retrieval during the sampling in the Ancona port.
The depth of the sampling stations was between 6 and 10 m inside the port and 14-15 m outside. Sediment samples for pathogens were collected by the use of a box-corer to keep the surface intact. The top 1 cm was preserved in sterile test-tubes with filtered (0.22 µm) sea water and immediately processed in our laboratory.
