The effects of experimental temperature increase on gametogenesis and heat stress parameters in oysters: Comparison of a temperate-introduced species (Crassostrea gigas) and a native tropical species (Crassostrea corteziensis)

The effects of experimental temperature increase on gametogenesis and heat stress parameters in oysters: Comparison of a temperate-introduced species (Crassostrea gigas) and a native tropical species (Crassostrea corteziensis)

The effect of thermal stress during reproduction was experimentally evaluated in the oyster Crassostrea gigas, a temperate species, and in the tropical oyster Crassostrea corteziensis. The temperature was gradually increased (1 °C day−1) from 20 °C to 34 °C for two weeks. As expected, C. gigas was t...

Zusammenfassung:The effect of thermal stress during reproduction was experimentally evaluated in the oyster Crassostrea gigas, a temperate species, and in the tropical oyster Crassostrea corteziensis. The temperature was gradually increased (1 °C day−1) from 20 °C to 34 °C for two weeks. As expected, C. gigas was the species most affected by heat stress, with the highest mortality rate (P
