Acartiella sinensis
Taxonomic Group: Crustaceans-Copepods


Acartiella sinensis is a planktonic calanoid copepod. It is native to estuaries in Southeastern China, Thailand and Sri Lanka. It is associated with warm, low-salinity waters and has been recorded in ballast water aboard commercial vessels arriving on the US West Coast. It is established in San Francisco Bay, California and individuals have been found in the Columbia River, Oregon, but a population is not known to be established there. It is abundant in San Francisco, but the extent to which it has had any impacts on native species or foodwebs, if any, is unknown.
