Highlights
• nkaα1a, nkaα1b and nkcc1a provide relevant information that the NKA activity does not reflect.
• While nkaα1a and nkcc1a transcription are mainly regulated by temperature, nkaα1b is regulated mainly by photoperiod.
• High water temperature could potentially compromise the adaptive and innate immune response of rainbow trout.
• Increased water temperature (8 °C) during winter does not provide clear advantages for smoltification or size at harvesting.
