South East Queensland Fish pack all fish in plastic bags with oxygen and water.
If possible, place the bag in an esky or a cool dark place for the trip home. The fish
will last for several hours comfortably when packaged like this.
When at the dam/tank, float the bag for 5-10 minutes in the water. After this time
open the bag and add some of the dam water to the bag until it is about half full.
Leave the bag float for a further 5-10 minutes then let the fish go.
The whole process should take no longer than 20 minutes. Try to do this in the shade
and do not do this in the heat of the day. Try and add the cooler water from
the deeper water in the dam, not the hot water on the surface.
If the fish start gasping at the surface of the water while still in the bag, let the fish go immediately.
