Perkinsus marinus IN Crassostrea gigas AND Chione fluctifraga FROM KINO BAY, SONORA, MEXICO

"At present, the Pacific oyster Crassostrea gigas is the most cultivated shellfish in northwest Mexico. Nonetheless, other mollusks species such as the black clam Chione fluctifraga, which can be found along with cultured C. gigas in Sonora, represents a profitable emerging fishery resource. Si...
