Two stories out of the Lafourche Parish Daily Comet in Louisiana discuss the non-existent market for nutria fur:
“Demand for Nutria Pelts Fades Away“
And
“They’re the Last of the Swamp-Rat Skinners“
The state of Louisiana gives $5 per nutria tail in an effort to control the population of the nuisance species, but pelts sell for as little as $1 when trappers can find a buyer.
