White shrimp are known from Fire Island, New York south to St. Lucie Inlet, Florida. The range then extends around the Florida Peninsula into the Gulf of Mexico from the Ochlocknee River in northwest Florida to Campeche, Mexico. Several centers of abundance have been identified for P. setiferus. Primary among them is coastal Louisiana around the Mississippi River Delta. Other abundance areas occur in northeast Florida, Georgia, and the region around the Bay of Campeche, Mexico (Williams 1984). White shrimp are distributed throughout the Indian River Lagoon and along the east central Florida coast where they are commonly utilized as bait and for food.
