First I would like to say that maybe only shad know how to keep shad alive. Seems that the second they lose contact with water they start to die. Several years ago I started making bait tank's, bait corral's and any other thing that I could think of to try to keep this fish candy alive without breaking the bank. Here's what I have learned. Cold water holds more dissolved oxygen than warm water. With the shad in the bait tank slowly cool the water down about 10 to 15 degrees per hour until your water is between 60 and 70 degrees. Most all commercial bag ice is non chlorinated so you should be ok there. Blue colored Round and oval tanks are best.(What can I say? They like blue ok) Even better if the water circulates around inside the tank at 1 to 3 miles per hour to keep the shad swimming in one direction and not into the side of the tank and getting red noses. If you are using a bilge pump try to keep the pump and any piping away from the side of the tank or the shad will keep running into it. With a bubble aereator it won't matter much. For aeration the smaller the bubbles the faster dissolved oxygen is transfered into the water. If you are using a bilge pump try running a small air line with an aquarium valve from the top of the tank to the water inlet on the pump to suck air into the impeller for aeration works good. Use the valve to regulate the air going into the bilge pump inlet. Basically if you have ever looked at a Keep Alive aerator this is about the same priciple, just cheaper. Add 1 cup of non-iodized salt (rock salt works good)for every 10 gallons of water to help protect the slime coat and keep from losing scales. Keep the foam from building up on top of the water. I just use my dip net but products like Foam Off are also available. If foam quickly becomes a problem you may have too many shad in the tank. Don't croud your bait tank. About 1 to 2 shad per gallon of water is all it will support. If you catch your own shad, put them in a clean 5 gallon bucket of lake or river water for a few minutes so they can poop in the bucket instead of your bait tank. You'll quickly see how nasty they are. Use a dipnet to transfer them from the bucket to your bait tank. Now it's time to fish. I should also tell you that when you take a 60 to 70 degree shad and throw him into 85 degree water he will go into shock and may appear dead for a minute or two but should recover. I hope this will help those that have tried or are tring to keep shad or bluebacks alive.
