DO THE DISC BLADES HURT THE CRAWFISH?
It looks like they should.
By the time we start disking, the ponds have already been drained and the bottom is dry enough to support a tractor. Then we pull rows of heavy steel blades through that dirt to break apart the hardened ruts and clods left behind from crawfish season.
But the important part is understanding where the crawfish are by then.
As the water level drops, mature crawfish move into burrows. Many of the females that will produce next year’s crop burrow along the waterline and into the levees, where the soil stays moist through the summer.
Those burrows can extend several feet below the surface. LSU describes Louisiana crawfish burrows as usually less than about 40 inches deep, while a typical agricultural disc is only working the upper several inches of soil. Some crawfish burrows can even get up to 25 feet deep.& ;
We’re also disking the pond bottom. We are not running those blades deep through the levees where a large portion of our reproductive crawfish are protected.
That distinction matters because heavy renovation of a levee absolutely can damage crawfish burrows or seal crawfish underground. LSU specifically warns farmers about doing extensive levee work after crawfish have burrowed.
So after watching those blades tear through the pond, the answer to the question is:
For the overwhelming majority of the crawfish we’re depending on for next season, no.
They’re already safely underground while we work above them, preparing the pond they’ll return to when we flood it again this fall.
