Winter weather temporarily froze crawfish harvesting and its market, but spring weather has started to melt away the effects as the catch and size increase. The arctic air brought freezing temperatures, power outages and water-access issues across most of Louisiana. As a result, many of Acadiana's ponds had a thin layer of ice on the surface. At the mud line, where crawfish grow, the temperature dropped to about 35 degrees, causing the cold-blood crustaceans metabolism to slow dramatically, said Mark Shirley, LSU AgCenter aquaculture specialist. "The freeze didn't kill the crawfish; it just delayed the harvest and delayed growth," he said. "At the same time, it was so cold, people didn’t move didn’t go out to eat. During that whole week, there was almost no demand because people didn’t get out or wouldn’t get out."
