Induction of triploidy in Rhamdia quelen (Siluriformes, Heptapteridae) by double-temperature shock

Induction of triploidy in Rhamdia quelen (Siluriformes, Heptapteridae) by double-temperature shock

This study evaluated sequential double-temperature shock (heat and cold) to induce triploidy in Rhamdia quelen. Fertilized eggs were heat shocked at 37, 39 and 41°C at 2 min post-fertilization and then cold shocked at 1°C for 20 min. Intact eggs were used as controls. Egg viability in control groups...
