Crayfish, which can be found globally in rivers, lakes, and swamps, are freshwater crustaceans similar in flavor to lobster and shrimp. While 95 percent of the crayfish eaten in the United States are caught in Louisiana, there are over 500 species of crayfish worldwide and over half of them are native to North America. Out of the 330 kinds of crayfish found in the United States, the most commonly consumed are red swamp crayfish (Procambarus clarkii) and white river crayfish (Procambarus acutus)—they have nearly identical flavors and can be used interchangeably.
