Assessment of oocyte and trochophore quality in Pacific oyster, Crassostrea gigas
Pacific oyster hatchery production remains highly variable, partially due to inconsistent gamete quality. However, little attention has been paid to oocyte quality in Pacific oyster compared to important vertebrate aqua-culture species such as fishes. The aims of the present study were to identify c...
