If you're going to transport the fish, be aware of ammonia and CO2 buildup. The CO2 buildup will help the fish because it will lower the PH and the toxic ammonia (NH3) will change into less toxic NH4 (ammonium). Once you open the bag and the PH starts to rise again, the NH4 will change back into NH3. You could add some Prime once the bag of fish reaches it's destination.
If you will be aerating along the trip, the aeration will drive off the CO2 and ammonia (NH3) will build up, so add some Prime before you leave in order to bind the ammonia.
Also adjust accordingly for PH differences between the bag of water and the destination QT tank or pond.
