One of the prominent sources of aquatic invasive species to coastal regions, are the ballast waters discharged from ships, through which invading microorganisms can reach the bay regions, producing major contamination. For this reason, samples of the ballast water from the ships in international traffic that arrived in Tumaco were taken to identify the presence of microorganisms. The survey was conducted during the period from April to October 2010, in 48 ballast water tanks from the 18 ships that arrived at the Ecopetrol Buoyage Terminal in the Bay of Tumaco. In this universe, it was determined if there were Vibrio cholerae in these water samples and at the same time, it served to determine the physical-chemical conditions of the water ballast tanks of these ships. The result was that in 12 vessels the presence of Vibrio cholerae was confirmed, which means that 67% of the ships surpass the permissible level (absence/100ml), allowed by the International Maritime Organization (IMO).Downloads
