1st Record: CA/San Francisco Bay 'where the salinity was lowest' (1913, Esterly 1924) Genetic studies by Lee (2000) indicate that San Francisco Bay populations belonged to the Atlantic subclade, and were distinct from most other populations on the Pacific coast of North america, but closely related to Atlantic Coast populations, providing evidence that these populations re introduced (Orsi 2002)
Geographic Extent
CA/San Pablo Bay;-Carquinez Straits (Ambler et al. 1986; Lee 2002, Orsi 2002).
