Instructions
Pour a 3-inch layer of soil in the bottom of a large plastic container. The soil is used to plant rice.
Pour fresh water into a large plastic container to a depth of 8 inches.
Poke holes 2 inches in depth into the soil and insert germinated rice seedlings. Space the holes 2 inches apart. Crayfish eat micro-organisms that feed off the rice.
Connect a 1/4-inch tube to the output of an air pump. Insert the tube into the large plastic container and press the ̶0;Power̶1; button to turn on the air pump. The length of the tube should be similar to the length of the plastic container.
Keep the temperature of the water between 65 to 85 degrees Fahrenheit. Measure the temperature of the water with a thermometer.
Heat water in a cooking pot on the stove. Add the hot water or ice to the container as necessary to keep the temperature within the preferred range.
Insert the crayfish into the water after the rice seedlings start to grow. Wait approximately one to two weeks.
