How to Keep Wild Crawdads

Crawdads are frequently eaten as a delicacy in the South, used as bait for fish or as food for pet turtles, but they can also be kept as pets themselves. Catching wild crawdads is relatively easy but keeping them in captivity requires a little bit of planning and maintenance. Before you endeavor to keep wild crawdads for bait, food or as pets learn what equipment and what type of tank set-up is necessary to keep these creatures healthy in captivity.

Instructions

    • 1

      Prepare a glass or acrylic aquarium for your crawdads. Make it no smaller than 5 gallons in size for a single crawdad but, if you plan to keep multiple crawdads, use an aquarium no smaller than 15 or 20 gallons.

    • 2

      Fill the aquarium to a depth of 3 to 4 inches with water and pour in some sand or gravel substrate to a depth of 1/2 to 1 inch.

    • 3

      Place large rocks, branches or even aquarium decorations inside the tank. Provide your crawdads with places to hide but do not overcrowd the aquarium with decorations. Some pieces should be entirely underwater while others should stick out of the water so the crawdads can climb out if they want.

    • 4

      Maintain a water temperature between 70 and 80 degrees Fahrenheit through the use of a submersible aquarium heater and aerate the water in the tank using an aquarium filter or an air stone.

    • 5

      Maintain a pH in your crawdad tank around 7, which is neutral on the pH scale. Use pH test strips to monitor the pH level and make adjustments when necessary. To maintain pH in your tank you can sprinkle some sterilized egg shells into the water. When the water in the tank becomes too acidic, the egg shells dissolve and the pH stabilizes.

      Feed your crawdads twice a day with sinking fish food pellets. Sprinkle a small amount of the food in several places around the tank so your crawdads have to forage to find it.
