Abstract
Zooplanktons in ship ballast water is an important factor in marine bioinvasion. From September 2008 to January 2009, two hundreds ballast water samples were collected from oversea ships arrived at Sai Gon port. Results of taxonomical analysis identified 43 zooplankton taxa, 5 groups of shrimp larvae, crabs, polychaeta and 1 unidentified species. Among the zooplankton species identified, there were 9 species that were not seen in Viet Nam from previous studies. They are Pseudodiaptomus clevei, Bestiolina sp., Pseudodiaptomus sp., Harpacticus sp., Amphiascus sp., Jalysus sp., Hemicyclops sp., Kelleria sp., Stephos sp. and one unidentified species.
