摘要The role of ballast water in the introduction of exotic species has recently received extensive attention. The aim of this study is to assess the importance of ballast water discharge as a vector for the introduction of exotic species into Hong Kong waters. Twelve ballast water samples were collected from 5 container ships entering Hong Kong between June 1994 and October 1995. The ballast water originated from ports on both sides of the Pacific Ocean. At least 81 species from 8 animal phyla and 5 protist phyla were found. Most of the major marine taxonomic groups were represented and many planktonic larval stages were included. Species richness in the ballast tanks decreased with the age of ballast water. Copepoda was the most diverse and abundant taxonomic group. The density of calanoid and cyclopoid copepods decreased with the age of ballast water, but that of harpacticoid copepods did not change significantly with time. Bivalve, crustacean, polychaete and ascidian larvae from ballast water samples were observed to settle in laboratory culture tanks. The mussel Mytilopsis sallei which was introduced to Hong Kong in 1980, was one of the bivalves that settled readily. Results of this study indicate that ballast water can be a major source for the introduction of exotic species to Hong Kong waters. Regulatory guidelines on the discharge of ballast water should be established.
