If you look at their website on quarantine procedures for DD, the fish salinity is 1.025 (just coming from Wisconsin). According to FAQ, CA facility is kept at 1.018 - 1.020 for fish.

Thank you for the link!
My last two shipments from the CA facility arrived at 1.015, 1st shipment was two weeks ago, and 2nd one arrived yesterday. And yes it was calibrated, and confirmed.
