transfert progressif

CONT: [...] d'autre part, d'évaluer les conséquences à court et moyen terme des modalités de transfert en mer en comparant un transfert direct à 35 % de salinité à un transfert progressif (augmentation graduelle de la salinité).

CONT: When transferring coho salmon ... the osmotic stress appeared much more acute and difficult to control. Subsequently, even if no short-term mortality occurred, the long-term results were poor in waters of high salinity ( [greater or equal to] 30 %). Under these circumstances, a progressive transfer or preadaptation to lower salinities may improve the results.
