Crawfish was almost unknown in Texas, but it was only a matter of time before Louisiana residents introduced the food to Texas in a big way. That started in Mauriceville, which was officially named “Crawfish Capital of Texas” in 1983 by the Texas Legislature.
 
Perhaps the legislature acted too soon. There are crawfish festivals all over Texas, and the Mauriceville Crawfish Festival is matched with the Old Town Spring “Texas Crawfish & Music Festival.” Is tiny Mauriceville still the capital, or has it moved?

Down in Texas, Farmers Raise Crawfish
by Peter Applebome
MAURICEVILLE, Tex.

Twelve years after Mr. Roy started raising what non-Cajuns know as crayfish, farmers all over southeastern Texas are flooding their rice fields, buying steel traps and trying to produce the spiny crustacean, which, as the unofficial state dish of Louisiana, is traditionally thought to be as much a part of that state as chili is a part of Texas.
 
“My neighbors wouldn’t talk to me for three years,” recalled Mr. Roy, who began raising crawfish as a sideline to his more conventional catfish farm. “They said, ‘That Cajun doesn’t have a lick of sense.’ Now this place is the crawfish capital of Texas.”

The retailing arm of the Texas crawfish empire is Mauriceville, which, despite its modest population of 175, has already put up signs billing itself as the crawfish capital of Texas.
 
The main business in town is an establishment called Crawfish Capital Sales and Crawfish LaMaurice, which is probably Texas’s first real crawfish restaurant. In season it offers a $9.95-all-you-can-eat dinner that is the backbone of the classic Cajun nine-course meal—a six-pack and three platters of crawfish.
