A Louisiana researcher is using underwater lights at night to grow more and bigger crawfish.
Julie Delabbio is director of Northwestern State University's Aquaculture Research Center, and she says her work shows that ponds with a dozen lights per quarter-acre produce about one-third to
two-thirds more pounds of crawfish than unlit ones.
She says that's about 800 to 1,000 pounds of crawfish per acre compared to 500 to 600 pounds in unlit ponds.
Crawfish farmer Robert Buller of Whiteville says that's a pretty good increase.
But other farmers say they don't think it's feasible or cost effective to light large ponds.
Delabbio says she's looking at solar power, LEDs and other ways to cut the costs.
Her work is important as the U.S. looks to increase its domestic aquaculture.
