Abstract
The objective of this study was to identify the survival and triploidy rates in rainbow trout under pressure and heat shocks induced at different times after fertilization. Fertilized eggs were exposed to a heat shock of 28°C for 10 minutes at 10, 15 and 20 minutes after fertilization. Survival rates were higher at 15 min and triploidy rates were higher at 20 min applications. Also pressure shock of 48263 kPa (7,000 psi) was applied to eggs for 4 min at 35, 40 and 45 min after fertilization, and higher survival and triploidy rates were observed at 40 min treatment. These results also show that pressure shock is more advantageous comparing with heat shock in all stages of development (embryo, eyed-stage, hatching, and first feeding) in both respect of survival and triploidy rates.
