The Reef Volunteer Fish Survey Project allows volunteer SCUBA divers and snorkelers to collect and report information on marine fish populations. Keep track of the fish you see while scuba diving or snorkeling. Submit those to an online database.
REEF surveys can be done anywhere along coastal areas of North and Central America, Bahamas and Caribbean, Tropical Eastern Pacific, Hawaii, the South Pacific, Central Indo-Pacific, Indian Ocean and Red Sea, and Eastern Atlantic and Mediterranean.
