Abstract
By using heat shock, we have induced triploidy in the offspring of gil thead seabream (Sparus aurata). We have verified that the effectivenes s of the treatment in this marine species depends not only on the thre e factors habitually considered (incubation time, treatment intensity and treatment time), but also on the salinity of the treatment water. The most effective treatment to provoke triploidy in this species is t o apply a heat shock of 34 degrees C for 10 min without an incubation period and with water salinity at 30 : 1000.
