Here in New Orleans, America's only historically-Catholic city, abstinence from meat (dating back to the days when such was still actually observed by the population at large) has never meant anything except for increased consumption of seafood, which is especially tasty and plentiful hereabouts.

Especially crawfish ~ a delicacy whose annual harvest (i.e., greatest abundance and lowest prices) annually coincides with the post-Mardi Gras season historically known as "Lent."
