Despite cooling systems for temperature regulation, the temperature was 0.7◦C (average) lower in mRAS compared to cRAS. When comparing larval size at the same day degree (d◦), the temperature difference effect on individual larval dry weight (average DW for each tank) was corrected for at each sampling time accord-ing to Eqs. (2) and (3) (Attramadal et al., 2012a):
