In the history, local Native Americans were the group who led to the introduction of crawfish into the Acadian diet. And as the Acadians became the Cajuns, the tradition of eating crawfish continued, leading to the popular methods of consuming the crustaceans today.
Today many rice farmers grow crawfish alongside their rice crop. The muddy ponds rice is grown in are a perfect environment for crawfish. Demand for crawfish has grown so high that crawfish farming is now required for meeting a consumer need. Roughly 90% of all crawfish coming from Louisiana is farmed, creating a $120 million a year industry.
