Save energy – these are not fish. 40+ years prawn DO testing…optimal range for growth and survival to 20g is 4-6 mg/ml…

Dissolved Oxygen in estuaries, where there is an abundance of benthic detritus eating vannamei, sits around 5 mg/ml.

In shrimp ponds the range is from 2-10 – due, not to shrimp, but algae and bacterial respiration diurnally.
