Mild weather helps crawfish season get off to fast start
Above-average temperatures in November and December have helped Louisiana’s crawfish season get off to a fast start.
Water temperatures in some ponds were as high as 75 degrees at the end of December, which kept newly hatched crawfish active and growing. These weather conditions led to many crawfish reaching market size in late December and early January.
“When the water temperature is jumping between 60 and 70 degrees, that’s optimum for crawfish growth,” said Mark Shirley, an aquaculture agent for the LSU AgCenter and Louisiana Sea Grant.
