Distribution, abundance, biology and fisheries potential of the exotic varnish clam (Nuttallia obscurata) in British Columbia / G.E. Gillespie, M. Parker and W. Merilees. : Fs70-1/1999-193E-PDF
Varnish clams have recently become established in Georgia Strait, and have been found in Barkley Sound on the west coast of Vancouver Island and estuaries in Oregon. They are dispersing southward to Puget Sound, and could spread northward into the Central Coast, similar to manila clams. This paper discusses distribution and dispersal of varnish clams and collects available information on biology, ecology and population dynamics. This information is summarized, and gaps in required information are identified. The fishery potential, management approaches and assessment information requirements to develop and evaluate the effectiveness of management tactics are discussed. The paper suggests that varnish clams have potential as commercial and recreational resources, and should be managed accordingly.
