Species-Specific Transcriptomic Responses to Thermal Stress in Baikal Whitefish Larvae: Wild Release Potential and Aqua-culture Fitness

The juveniles were kept for 1.5 months at 9–12 °C and then exposed to acute stress (heating to 21 °C for 1 hour) and chronic stress (heating to 21 °C for 24 hours 3 times a week). These findings help explain why some fish species thrive in aquaculture while others struggle, and provide valuable markers for monitoring fish welfare under changing environmental conditions.
