Marbled Crayfish are very useful in the area of AQUAPONICS, or recirculating garden systems. The basic principle is simple: live fish provide waste which is pumped into plant containers to feed root systems. The water is filtered by the plant roots and returns clean and fresh into the fish tank, where edible species of fish are grown.
However for small systems in particular (for personal dwellings), marbled crayfish supply a plentiful amount of waste for plants to feed on in a small space. They are also a self cloning animal, meaning they multiply into a colony. Interesting also is that this species of crayfish eats primarily plant materials, like aquatic plants or sliced cucumbers.
Wastewater from Marbled Crayfish tanks can also be used on plants where it is too hot to keep live animals in outside tanks. Some greenhouse operations use the wastewater from marbled crays!
