Introduced marine pests in Korea

Korea's busy shipping ports have been the first homes for many marine animals and plants introduced into its waters.

Like most coastal waters, Korea's cool seas are home to alien species from other parts of the world. These plants and animals are often transported from one sea to another in the ballast holds of ocean-going ships.

At the time this page was written, there is no special program in Korea to investigate introduced marine pests. Nevertheless, visiting scientists and Korean marine biologists have identified a number of marine species that appear to have been introduced through ships' ballast water.

These include a South American barnacle and the Northern European blue mussel, which is believed to have been introduced by a French ship visiting Korea. Some Korean scientists have also found evidence of the spread of the Southern European mussel, which is farmed in southern Korea and is slowly making its way northwards along the coast.
