	abstract = {For about 3 years, the Whiskey Creek Shellfish Hatchery has been producing commercially a new kind of triploid Pacific Oysters (Crassostrea gigas) called "Natural" or "100\%" triploid, made from the cross between regular diploids and tetraploids. The first advantage is that these "natural" triploids are always 100 percent triploid as verified by flow cytometry, insuring a high quality product for the customers. Hatchery seed was deployed in grow out bags at two different locations for a 26-month study to examine the growth performance (length, whole weight, meat weight) and gonadal development of the natural triploids, chemical triploids and diploids. The "natural" triploid outperformed both diploids and chemical triploids on most of the characteristics studied. The final length was increased by 7 to 9\% in the natural triploids compared to the diploids, the whole weight improved by 30 to 40\% and the meat weight by 19\% in the most productive area. The "natural" triploids outperformed as well the chemical triploids, with an increase of 7\% in length, 15\% in whole weight and 18\% in meant weight in the most productive area. No histological differences were detected between "natural" and chemical triploids, but their gametogenesis was significantly reduced when compared to the diploids for the females and to a lower extent, for the males.},
