Pearl hunting is the act of recovering pearls from wild mollusks, usually oysters or mussels, in the sea or fresh water. Pearl hunting used to be prevalent in the Persian Gulf region and Japan, but also occurred in other regions.
Before the beginning of the 20th century, the only means of obtaining pearls was by manually gathering very large numbers of pearl oysters or mussels from the ocean floor or lake or river bottom. The bivalves were then brought to the surface, opened, and the tissues searched. More than a ton were searched in order to find at least 3-4 quality beds.
In order to find enough pearl oysters, free-divers were often forced to descend to depths of over 100 feet on a single breath, exposing them to the dangers of hostile creatures, waves, eye damage, and drowning, often as a result of shallow water blackout on resurfacing. Because of the difficulty of diving and the unpredictable nature of natural pearl growth in pearl oysters, pearls of the time were extremely rare and of varying quality. The Great Depression in the United States made it hard to get good prices for pearl shell. The natural pearls found from harvested oysters were a rare bonus for the divers. Many fabulous specimens were found over the years. By the 1930s, overharvesting had severely depleted the oyster beds. The government[which?] was forced to strictly regulate the harvest to prevent the oysters from becoming extinct, and the Mexican government banned all pearl harvesting from 1942 to 1963.
In Asia, some pearl oysters could be found on shoals at a depth of 5–7 feet (1.325–2 meters) from the surface, but more often divers had to go 40 feet (12 meters) or even up to 125 feet (40 meters) deep to find enough pearl oysters, and these deep dives were extremely hazardous to the divers. In the 19th century, divers in Asia had only very basic forms of technology to aid their survival at such depths. For example, in some areas they greased their bodies to conserve heat, put greased cotton in their ears, wore a tortoise-shell clip to close their nostrils, gripped a large object like a rock to descend without the wasteful effort of swimming down, and had a wide-mouthed basket or net to hold the oysters.
For thousands of years, most seawater pearls were retrieved by divers working in the Indian Ocean, in areas such as the Persian Gulf, the Red Sea, and in the Gulf of Mannar (between Sri Lanka and India). A fragment of Isidore of Charax's Parthian itinerary was preserved in Athenaeus's 3rd-century Sophists at Dinner, recording freediving for pearls around an island in the Persian Gulf.
Pearl divers near the Philippines were also successful at harvesting large pearls, especially in the Sulu Archipelago. In fact, pearls from the Sulu Archipelago were considered the "finest of the world" which were found in "high bred" shells in deep, clear, and rapid tidal waters. At times, the largest pearls belonged by law to the sultan, and selling them could result in the death penalty for the seller. Nonetheless many pearls made it out of the archipelago by stealth, ending up in the possession of the wealthiest families in Europe. Pearling was popular in Qatar, Bahrain, Japan, India and some areas in Persian Gulf countries. The Gulf of Mexico was particularly famous for pearling, which was originally found by the Spanish explorers.
In a similar manner as in Asia, Native Americans harvested freshwater pearls from lakes and rivers like the Ohio, Tennessee, and Mississippi, while others successfully retrieved marine pearls from the Caribbean and waters along the coasts of Central and South America.
In the time of colonial slavery in northern South America (off the northern coasts of modern Colombia and Venezuela), a unique occupation amongst slaves was that of a pearl diver. A diver's career was often short-lived because the waters being searched were known to be shark-infested, resulting in frequent attacks on divers. However, a slave who discovered a great pearl could sometimes purchase his freedom.
Pearl hunting in colonial Latin AmericaEdit
During the first half of the sixteenth century, Spaniards discovered the vast and luscious pearl oyster beds that existed on the Caribbean coast of Venezuela, particularly in the vicinity of Margarita Island. Indigenous slavery was easy to establish in this area because it had not yet been outlawed; therefore, indigenous peoples were captured and often forced to work as pearl divers. Since violence could not protect the efficiency of the slave trade, coastal chieftains established a ransoming system known as the "rescate" system.
As this system continued to grow, more and more oyster beds were discovered along the Latin American coast, including near Riohacha on Colombia's Guijara Peninsula. However, due to over-exploitation of both indigenous labor and the oyster beds, the Spanish pearl economy soon plummeted. By 1540, previous Spanish settlements along the coast had been abandoned as the Spanish looked elsewhere for more labor and newer markets. The pearl industry was partially revived in the late sixteenth century when Spaniards replaced indigenous labor with African slave labor.
Oyster harvesting methods remained relatively the same along the coast and varied depending on the divers' conditions, the region's topography, and a Spanish master's work demands.
On Margarita Island, small zones were inspected in advance by the divers, who relied mostly on lung power to dive and resurface from the ocean. Once those small zones had been depleted of their oysters, the men on the boat - which usually included a dozen divers, a Spanish navigator, a diving chief, an oarsmen, and a foreman - moved on to the next oyster bed. To retrieve the pearls, the divers carried a small net that had one end tied to the boat and the other end tied to the fishing net. The shells that they extracted were usually placed in this basket, but for dives of greater depth, the divers also had to wear stones tied to their bodies as they submerged into the ocean. The stones acted as a ballast until they resurfaced, where the divers then untied the stones from their bodies. The divers would receive a slight break to eat and rest and continue this work until sundown, where they all presented their catch to the foreman, return to the Spanish ranchería to have some dinner, and then open the oyster shells.
The divers were locked in their quarters at night by the Spaniards, who believed that if the divers (who were mostly male) compromised their chastity, they would not be able to submerge but rather float on the water. The divers who either had a small catch or rebelled were beaten with whips and tied in shackles. The working day lasted from dawn till dusk and being underwater, along with bruises, could affect the health of some divers. Furthermore, it is well known that the coastal waters were often infested with sharks, so shark attacks were quite frequent as well. As the fisheries continued to diminish, slaves hid some of the valuable pearls and exchanged them for clothing with their bosses.
On Cubagua, another Venezuelan island, the Spaniards used natives as slave labor in their initial attempts to establish a thriving pearl market in this area. Indians, especially those from Lucayo in the Bahamas, were taken as slaves to Cubagua since their diving skills and swimming capabilities were known to be superb. Likewise, the Spaniards began to import African slaves as the indigenous populations died off from disease and over-exploitation and Africans became so preferred by the Spanish over indigenous labor that a royal decree of 1558 decreed that only Africans (and no natives) should be used for pearl diving. Like other pearl diving groups controlled by the Spanish, the pearl divers could be treated harshly based on their daily pearl retrieval. Unlike the other pearl diving groups, however, the divers on Cubagua were marked by a hot iron on their face and arms with the letter "C," which some scholars argue stood for Cubagua.
The pearl diving process in Cubagua varied slightly from other Spanish pearl diving practices. Here, there were six divers per boat and divers worked together in pairs to collect the pearls. These pearl divers used small pouches tied to their necks to collect the oysters from the sea bottom. Some scholars have reported that because of the climate in Cubagua, the heat would cause the oysters to open themselves, making the pearl extraction process a bit simpler. Natives, unlike Africans, were given less rest time and could potentially be thrown off the boat or whipped to commence work sooner. Similar to slaves on Margarita Island, all pearl diving slaves were chained at night to prevent escape; in addition, deaths not only resulted from shark attacks, but also from hemorrhaging caused by rapid surfacing from the water and intestinal issues induced by constant reentry into cold water.
Diver groups in the Panamanian fisheries were larger than those on Margarita Island, usually comprising 18 - 20 divers. Instead of net bags, these divers surfaced with oysters under their armpits or even in their mouths, placing their catch in a cloth bag on board the ship. Each diver would continue to submerge until he was out of breath or extremely tired, but also after they had met their fixed quota for the day. Once the bags were full, the divers caught another breath and immediately began pearl extraction aboard the vessel, handing the pearls to the foreman who accounted for both imperfect and perfect pearls. Excess pearls were given to the divers who could sell them to the vessel owner at a just price; in contrast, if the divers did not meet their daily quota, they would either use their reserve pearls to fulfill the quota for the next day or write that amount of pearls into a debt account. Like the Venezuelan divers, the Panamanian divers also faced the danger of shark attacks, although they usually carried knives to defend themselves.
Today, pearl diving has largely been supplanted by cultured pearl farms, which use a process widely popularized and promoted by Japanese entrepreneur Kokichi Mikimoto. Particles implanted in the oyster encourage the formation of pearls, and allow for more predictable production. Today's pearl industry produces billions of pearls every year. Ama divers still work, primarily now for the tourist industry.
Pearl diving in the Ohio and Tennessee rivers of the United States still exists today. Pearling in Highland rivers in Scotland was prohibited in 1995 after the mussel population was driven to near extinction, see Pearl#British_Isles.
