Evaluation of the gonad volume throughout magnetic resonance imaging in Crassostrea gigas and comparison with the histological method
Biological parameters of the cupped oyster Crassostrea gigas such as growth, reproductive effort (duration of the gametogenesis, date of spawning, and fecundity) differ widely among oysters in the same location. Furthermore, most of the traditional methods, like histological observations, could lead...
