Distribution map of Sinocalanus doerrii by geographical zones
Species Sinocalanus doerrii - Distribution map 2Issued from : M. Winder, A.D. Jassby & R.M. Nally in Ecology Letters, 2011, 14. [p.753, Fig.3, a].
Historical abundances of introduced species in the upper San Francisco Estuary between 1972 and 2009.
Adult stages are shown because immature stages were not continuously identified.
Loc:
China Seas (East China Sea, Changjiang River estuary, South China Sea, in W. Zhang & al., 2010) as dorrii), San Francisco Estuary, California (estuaries)

Rem.: Freshwater and brackish. Incomplete data.
For Orsi & al. (1983, p.357) this species native of the rivers of mainland China was found in 1978 in California's Sacramento-San Joaquin Estuary, abundant and may be regarded as well established. The introduction occurred a relatively short time. The most probable mode of introduction in ballast water from Japanese freighters previously docking in China, which discharge into San Francisco Bay.
