Use of microarray technology to assess the time course of liver stress response after confinement exposure in gilthead sea bream (sparus aurata l.)
Background: Selection programs for growth and stress traits in cultured fish are fundamental to the improvement of aquaculture production. The gilthead sea bream ( Sparus aurata) is the main aquacultured species in the Mediterranean area and there is considerable interest in the genetic improvement...

The gilthead sea bream ( Sparus aurata) is the main aquacultured species in the Mediterranean area and there is considerable interest in the genetic improvement of this species.
