Raising Crayfish In A Pond. Plant the rice crops between march and april in 2 inches of water. When stocking an aquaponic system with crayfish, you want to do less rather than more.

The bases of perimeter levees should be at least 9 feet wide to prevent leakage caused by burrowing crawfish. In the process of eating minute plants that grow on submerged vegetation, crayfish also eat larger pond plants, giving limited vegetation control. Crawfish typically are reared in shallow ponds of 18 to 24 inches in depth and from one to several acres in area.
