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.
In June and July sampling continues in the Port of Koper by the FB1 National Institute of Biology, Marine Biology Station, Piran, Slovenia.
The sampling is performed in all three basins of the port of Koper as each basin has its own specifics:
In all three basins ships discharge ballast waters.

Core samples were taken for meiofauna and dinoflagellate cysts on 11th June. The depth of the sampling stations was 11-13 m in the port basins and 17 m outside the port.

Additionally, on the 2nd and 12th of June and on the 4th of July sampling of macrofauna and flora was performed in the 1st and 3rd basin. The sampling was done along vertical transects on the wall and on three piles. Three sampling frames were fixed to the surface at different depths.

Quantitative destructive sampling of flora and fauna were performed by carefully scraping all organisms inside each sampling frame into collecting bags. Photographs of fouling communities were taken before scraping the sampling surface. Additional photographs of fouling communities in adjacent areas were made.
