Recently I transported 10 crappie, 1 channel catfish and 1 white bass from Jordan Lake to my house. The fish made it just fine. The lake is 2 hours away and we stopped to eat for 30-45 minutes. I transported them in a 48 qt. polar roller cooler and I used an aerator and my 12V trolling moter to keep water circulating. I also stopped and bought a bag of ice but did NOT open the ice since it did melt I didn't want to take the chance of the chlorine in that water to kill the fish. Here's my aerator. It has helped transport a lot of fish from pond to pond.
