What do you know about the profession of pearl diving?

The profession of pearl diving is becoming a thing of the past. And it originated about 4,000 years ago, when there was a demand for pearls. Why not dive in and look for a shell with a pearl, because you can get a good reward for it.So, at first they just dived, then a profession appeared, and then it became the source of existence for individual tribes and peoples. This profession is highly respected and very risky. It's not for nothing that skills that have been tested for centuries are passed down from generation to generation.Now many divers are forced to retrain, getting rare algae and various items from the bottom, which are still in demand.And pearls are now being mass-produced in special farms, and they are in abundance on the market. It is used in the jewelry industry, and it is the only gemstone that creates a living being - an oyster.In fact, the oyster's ability to create pearls is simply a defensive reaction of its body to the penetration of a foreign body inside the flaps. It can be a parasite, a grain of sand, or a drop of liquid. The oyster perceives such penetration as a threat to its existence and defends itself in an accessible way by isolating a foreign object and enveloping it with layers of mother-of-pearl.Oyster farms are now appearing everywhere where climatic conditions allow. And the Chinese were the first to think of putting a grain of sand or a piece of clay inside the oyster flaps. Even now, they have achieved great art in the production of pearl cultivation - the Hong Kong market is flooded with pearls.But natural pearls are still much more expensive, and there is a demand for them.Natural pearl deposits exist, and are mainly located in the Persian Gulf, on the shores of the Red Sea. These are Iran, India, Tahiti, Ceylon.Traditionally, pearl divers dive only with a knife and a net. Japanese ama divers, whose average age is about 15 years old, dive topless and in shorts, and even wear glasses so that the caustic sea water does not corrode their eyes. But pearl fishermen also appeared, equipped with the latest modern equipment, and from this the underwater plantations began to rapidly become impoverished.A traditional pearl diver dives from a boat. A stone is tied to the boat on ropes. The diver, holding the load in his hands, goes into the water. When he reaches the bottom, he releases the load, which moves on to the next pearl diver. At least, this is the method of diving practiced by the Parava tribe of India.Actually, you should rest for 12-15 minutes between adjacent dives, then the body has time to clear itself of the previous negative effects. However, in practice, this is not always maintained, and professionals can collect pearls from almost 200 shells in a day, making 40-50 dives for this.It takes time to work effectively underwater. By training and using certain techniques, many divers bring the time spent underwater to 50-80 seconds.These techniques and skills are passed on from fathers to children, and practical training begins from a very young age, almost from the cradle. So it turns out that by the age of 7-8, children can already dive into water several meters deep, and by the age of 15, they are already becoming full-fledged professionals.The ama women, Japanese pearl fishermen, dive themselves, and their men, using their remarkable strength, help to pull them and their catch out of the water. And a woman has the advantage that she has a fat layer under her skin, which makes it easier to resist hypothermia. Current ama have sometimes already begun to use modern costumes, fins and a mask.The diving profession is fraught with danger. Sometimes you have to evacuate urgently, because a shark, a water snake, and other troubles can lurk in the water. This is where masculine strength is needed to quickly remove the hunter from the dangerous neighborhood and urgently raise him to the surface.If divers took care of their health while working, and did not dive too often, then they keep their shape longer. If they were in a hurry to collect more catch, then by the time they were 30, they were already showing signs of caisson disease, and it was turning them into old men. Trembling hands, besides, affected by rheumatism, poor hearing and eyesight…In the old days, during the heyday of the profession, it was honorable and respected. For example, AMA women could choose their own husbands. But now the profession is dying out, and either enthusiasts or those who are unlucky with other jobs come to it. Naturally, but still sad.
