BLOG: Shrimp on Antidepressants Not So Happy
There may be one way to lick this problem, literally. The Louisiana Department of Wildlife and Fisheries has advised fisherman that the prawns should not be thrown back into any waters other than a boiling soup pot.
"I haven't had them myself, but I've been told they have a sweet flavor," Bourgeois said.
Tiger prawns could join the list of invasive species humans seek to control by eating, like wild pigs, lionfish and nutria, noted Mother Nature Network.
The tiger prawn also fetches a higher price than many other shrimp. But Leslie Hartman, of the Texas Parks and Wildlife Department, is skeptical the economic value will outweigh the damage to the native shrimp population.
"It could be another crop, but at the expense of our native crop," Hartman said in the Houston Chronicle.
For right now, researchers are trying to track down the source of the prawns using genetic evidence.
"We're collecting them, and we've got some researchers looking at the genetics," Bourgeois said. "It may help explain if they're spawning here or if they're riding the current into the area somehow."
Only adults have been found in Louisiana waters, so researchers hope they may be breeding farther south and migrating north.
