"Bulletin 178 entitled 'Pacific Oyster Raft Culture in British Columbia' is incorporated in this version"--Introduction, page 1. Includes bibliographic references (page 228-229). "Of the three species of oysters (Crassostrea gigas, Crassostrea virginica, and Ostrea lurida) that occur in British Columbia, only the exotic Japanese species (C. gigas) the Pacifie oyster, is now cultured. The anatomy of C. gigas is described in some detail as well as the reproductive process. Successful breeding of the species in most British Columbia waters is erratic except for certain areas such as Pendrell Sound, Hotham Sound, Ladysmith Harbour in Georgia Strait, Pipestem Inlet and Nootka Sound on the west coast of Vancouver Island. Collection of seed, particularly in Pendrell Sound is described in some detail. Methods of culture include intertidal and subtidal bottom culture, suspended string, stake, tray, and both suspended and intertidal stick culture."Harvesting, processing, and storage methods are described. The problems of Pacific oyster culture include industrial and sewage pollution, paralytic shellfish poisoning along with predators and disease. How these may be dealt with is discussed. Administrative aspects of this industry are reviewed"--Abstract, page vi. Includes abstract in French. gccst Molluscs Canada. Department of Fisheries and Oceans.
