Yes, as long as the BioFresh safe is set to a temperature of 0 °C, fish can also be stored perfectly well in the 0-degree zone of the refrigerator. If you want to keep your fish even longer, you should opt for BioFresh Professional with a Fish & Seafood safe. In this climate zone, the temperature can be lowered to -2 °C independently of the other compartments. This keeps fish and seafood fresh noticeably longer.
