Abstract

The transfer of harmful organisms by shipping, in particular through the ballast water transport, can result in a disruption of ecosystems, change of biodiversity, negative impacts on human health and economic loss. The introduction of species that produce irreversible consequences in the receiving environments and economies require special attention. One critical issue is the need to assess the amount and processes of species introductions. Therefore, at the terminal Ecopetrol Buoyage at Tumaco Bay (Colombia), 18 vessels in international traffic were sampled, as well as two reference sites for comparison. The phytoplankton and zooplankton of the samples were analyzed and the physicochemical parameters of both the ballast water tanks and reference sites were evaluated. The results can be considered as background information for an initial risk assessment of species introductions in the future and as an important tool for the implementation of measures for ballast water management.
