The first recorded English visitor was Sir Francis Drake in 1586, who reported that the "caymanas" were edible, but it was the turtles which attracted ships in search of fresh meat for their crews. Overfishing nearly extinguished the turtles from the local waters. Turtles were the main source for an economy on the islands. In 1787, Captain Hull of HMS Camilla estimated between 1,200 and 1,400 turtles were captured and sold at seaports in Jamaica per year. According to historian Edward Long the inhabitants on Grand Cayman had the principal occupation of turtle-fishery. Once Caymanian turtlers greatly reduced the turtle population around the islands they journeyed to the waters of other islands in order to maintain their livelihood.
