Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 21 - 80
Comments: Subspecies OXYRINCHUS of Atlantic coast: historically present in approximately 34 rivers in the United States from the Penobscot River, Maine to the St. Johns River, Florida. It is not known how many of these rivers supported spawning. The current range has contracted slightly, from the Kennebec River, Maine (absence from the Penobscot River has not been conclusively determined) to the Satilla River, Georgia. This subspecies is currently present in 32 rivers, and spawning occurs in at least 14 of these rivers (possibly up to 19) (Atlantic Sturgeon Status Review Team 1998, NMFS 1998).
