Shrimp of the genus Penaeus, collected in the southern Florida—western Bahamas area, were identified to determine species distribution and composition. Penaeus duorarum is the dominant species in southern Florida waters and, together with P. aztecus, occurs
along the lower east and west coasts of the State. P. brasiliensis occurs near the Florida Keys and along the east coast of southern Florida, and is apparently the dominant species in the western Bahamas. In Biscayne Bay, Fla., P. duorarum was more abundant than P. brasiliensis
in all catches examined.
