Record rains from Isaac could impact next season’s crawfish harvest. Rains that fell across much of southeast Louisiana have filled crawfish ponds ahead of their normal schedule. Dr. Greg Lutz, an aquaculture specialist with the LSU AgCenter, says high water now can spoil next year’s crawfish harvest.
“They’ve evolved over millions and millions of years to a pretty stable cycle of wet and dry conditions, and when things get wet too early, it tends to disrupt things.
“Lutz says Isaac struck the area just as many female crawfish were laying eggs in their burrows.He says most of them will stay with their eggs but some will respond by emerging early and those crawfish could be lost.
