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.
China Seas (East China Sea, Changjiang River estuary, South China Sea, in W. Zhang & al., 2010) as dorrii), San Francisco Estuary, California (estuaries)
N: 5
(1054) F: 1,44-1,73; M: 1,30-1,69; {F: 1,44-1,73; M: 1,30-1,69}
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.
