Resumen
The objective of this work is to develop a case study in order to improve the ballast water management in the Black Sea?s ports. From this perspective, the present paper provides an extensive explanation about the main issues related to the control of marine non-indigenous species introduction through ballast water discharged by ships during their operations in the ports. Thereafter, it quantifies the amount of the ballast water discharged in the major ports of the Black Sea and the amount of the invading species that could reach these ports. Although, globally speaking, the problem of ballast water management is a reality, only three of the six neighboring countries in the Black Sea basin have signed, in 2004, the ratification of the International Convention on Management of Ships? Ballast Water and Sediments. This is also known as the Water Ballast Management Convention, and it provides regulations concerning ballast water management generated by the shipping activities through a common set of rules.
