•Stress was monitored by measuring cortisol in water instead of in blood.•Fish adapted to regular prophylaxis/disinfection with peracetic acid by showing reduced stress.•A mathematic model was established to improve understanding of substance distribution in RAS.
- Water cortisol
- Solid phase extraction
- Mathematic model
