Physiological comparisons of Pacific cupped oysters at different levels of ploidy and selection to OsHV-1 tolerance
The production and supply of triploid oysters Crassostrea gigas has become an increasingly frequent activity in aquaculture companies to satisfy the growing demand of growers. These triploid oysters are usually obtained by crossing male tetraploid oysters with female diploid oysters. Furthermore, st...

The production and supply of triploid oysters Crassostrea gigas has become an increasingly frequent activity in aquaculture companies to satisfy the growing demand of growers. These triploid oysters are usually obtained by crossing male tetraploid oysters with female diploid oysters. Furthermore, studies have shown that it is possible to select oysters for better resistance to infection by OsHV-1 and they are currently produced by commercial hatcheries in France.The effects of ploidy and selection on the physiological functioning of the Pacific cupped oyster are still relatively unknown, especially in tetraploid animals selected for better resistance to infection by OsHV-1. In the framework of sustainable domestication, and by taking into account the natural habitat, it has become necessary to shed more light on the subject.Faced by this lack of knowledge, a physiological study of respiration and clearance rate was performed on 6 stocks of C. gigas oysters whose levels of ploidy (2n, 3n and 4n) and sensitivity to OsHV-1 resistance (selected and non-selected) were different.
