Early crawfish catch points to slow season

Almost immediately after the holidays, south Louisiana consumers start thinking about crawfish. Crawfish boils aren't uncommon the first warm weekend of the year. But according to an LSU AgCenter aquaculture specialist, early harvests are down this year, making crawfish a little harder to come by.

“As of right now, a lot of producers are off by as much as a third or a half of what they normally would have caught by this point in the season,” said Greg Lutz, LSU AgCenter crawfish expert.

The life cycle of a crawfish is complicated, and survival rates depend on several factors, Lutz said, adding that it looks like a few things went wrong last year to affect this year's crop.

“The summer was extremely dry in some areas. And generally when we see that, that means we're going to see low survival down in the ground in those burrows.”

Hurricane Gustav also affected crawfish survival. Heavy rains flooded many crawfish ponds, forcing crawfish out of their burrows early. The crawfish emerged into water that had plenty of debris and little oxygen.

“The crawfish were looking for ways to get up out of the oxygen-poor water, but birds, raccoons and other predators tend to eat them as fast as they come out of the water.”
