"Success in pearl cultivation

This story is not about the oysters that are found in sea water. But a story of the achievements of pearl producer, Ravikiran Bhat, a man from Karnataka State who has become an expertise in the art of pearl production.

He became successful in growing pearls indoor and inside the fresh water tanks.

Ravikiran Bhat, a young man from North Karnataka, India, has ventured into pearl cultivation, a rare adventure.

Ravikiran had an interest to learn astrology and the related planets. In the vedic astrology, pearl is the gem that belongs to Moon. He became more interested in knowing the details of pearl. And later he thought of cultivating the same, at his place.

This young fellow born on June 24, 1987, got his degree of MFSc in pearl farming, from the Freshwater fisheries Research Center CAFS(FFRC), Wuxi, Jiangsu, which is located in China. He collected lot of information through internet and learnt the pearl cultivation methods. He also came to know about the places where training is given for the same.

He visited the Central Institution of Fresh water Aquarium (SIFA) at Bhubaneshwar(Orissa state) and also the Kochin Central Marine Fisheries Research Institute (CMFRI) in Kerala state. He got the necessary training from experts there and learnt the techniques. He invested Rs.4 lakh initially before he entered the indoor fresh water pearl cultivation job.

Inside the fresh water troughs...

Today, Ravikiran Bhat has achieved the rare feat of becoming a successful pearl cultivator in India. After achieving this feat, he has become the only pearl cultivator in the whole of Karnataka. His interest to be a corporate leader is widely appreciated by the people of the state.

Within his house yard he has four fresh water ponds of 60 feet wide and 15 feet long, for the oyster cultivation. The age of the oyster is decided by the lines formed over them. Small oyster shells are useless. Therefore it is necessary to be careful while selecting them. Oxygen is supplied through pipes to maintain the cool of the river environment, within the water tanks. Sand and small lime shells are mixed into the pond water.

Three types of pearls are available in the market. Natural , artificial and the ones that get cultivated within the shells. Ravikiran has accepted the third one, the fresh water pearl cultivation.

Oyster operated
River water has in it 52 types of oysters. Lamellidens marginalis, Lamellidens corrianus, Parreysia corrugata types are of great importance in pearl cultivation.

After 10 days time, the selected oysters are placed in glass troughs and the good quality oysters will be ready to get operated.

Just before the operation, the oysters are given an anesthetic. For this, a tub is filled with water first and then anesthesia powder is added to it. Oysters are left in a condition of artificial respiration for about half an hour. Slowly they reach the subconscious state. During this stage, the oysters will be ready to get operated. So, this is an important part of pearl cultivation.

Ravikiran becomes a real doctor to these oysters, at this stage. Wearing a glouse, with tongs and plucker in hand, he operates 25 oysters per day.

At the Intensive Care Unit...

Oysters are taken out from the water when they are in a state of unconsciousness and operated. Through operation nucleus is inserted into the organ called Gonad(a small bead shaped thing which is imported from Japan).

Once again, the oysters are placed in troughs for artificial respiration. They will be tested again to see whether they have come back to consciousness. It is totally like a Intensive Care Unit. They will then be placed in the same position for 10 days. More cautiousness is required at this stage, because there will be every possibility of oysters losing their lives.

Month of January is considered to be best for operating the oysters. Oysters that undergo operation are placed separately in small meshes and will be hung down to a wooden ladder laid flat, over the tank. Thus the oysters that have got adjusted to the outer environment will be kept under a close watch. Finally, they are placed back into the oyster collection tank. Later, they will be there in collection for the next 1-1/2 years. As the nucleus is added causing trouble to the oyster, it gives out a sticky liquid called Nacre. This liquid is given out so as to escape from the trouble caused due to addition of the nucleus. Later, it gets transformed into a pearl.

To reduce pearl cultivation cost?

Better quality pearl can be obtained anyway. But the much needed color of the pearl is impossible to attain. So, it wears the same color that is present within the inner layer of the oyster. Pearl also gets cultivated in the similar fashion.

Nucleus will be imported for the sake of cultivation. The Geomentron sheets that are used in pearl collection tank are not available in India. Therefore they will be imported. Lakhs of rupees will be needed to invest into pearl cultivation.

These pearls are checked and tested in the international market when they get ready for the trading purpose, after cultivation. Only the expert consultants buy these pearls. There is a lot of demand for such pearls in the foreign countries.

Mr, Ravikiran says, As the farmers get more and more involved into the purchase of raw materials needed for pearl cultivation, easy methods may be found for the product marketing. Many a young unemployed people get the employment. Research as well as starting of good training centres will help farmers to get a systematic direction in this field.

These are his confident words.

The honors he recieved for his achievement

The State level award for Kannada Kuvara 2008, and State level award for young achiever 2008.

Ravikiran is now, the chairman at his Fresh Water Pearl Culture Research Center and actively involved in training the pearl cultivators who are interested in the pearl farming. He has started the Ravikiran's Pearl Foundation. He is training those people in 3-5 places of Chattisgarh and Andhrapradesh state. He also has plans to start the consultation centres in Karnataka state, this year."

Yashas cultivates freshwater pearls and exports the entire produce to France

As an 18-year-old, Ravikiran Bhat decided to cultivate pearls on an astrologer?s recommendation. But all the oysters he had implanted with nuclei (imported from Japan and made from oyster shells) died. That was 2005 and Bhat headed to China to study pearl farming at the Freshwater Fisheries Research Center in Jiangsu. ?Pearl farming involves patience. How could I give up after one failure,? he says.

Two years later, Bhat came back and re-started pearl cultivation, investing Rs 5 lakh. This time he was successful. He collects mussels from rivers, which are operated upon to implant the nucleus. They are later put back in a pond where, in about a year, pearls form in the shell. He exports all his pearls to France.

Bhat has expanded through a franchise model of sorts. He ties up with those who have land and water supply for rearing oysters, provides manpower and technology, including the nucleus. The only difference is that instead of selling pearls to customers, these clients sell them back to Bhat. ?I have 28 clients, in Malaysia and Singapore. In India, most of them are in Chhattisgarh, Tamil Nadu and Orissa,? he says.

That's such an interesting story, Cyril. Thanks for taking the time and effort to post it. You are definitely enriching the knowledge bank of this forum.
You are most welcome. Thanks for the comment.
Mr brossard, you sure do come up with the goods! Amazing article, anaesthisia for oysters? Wow! I never knew they used that for fresh water oysters! I wonder if it is a widespread technique? Or just his special one. On a better note, wow! Oysters have their own anaesthisia! What is it? I feel like a kid who just discovered shaking the soda can.
This is far from my field of expertise and it has been a few decades since my last hands-on experience with continental waters (fresh water). There is a wide range of anesthetic available (for various species) such as clove oil, rotenone, xylocaine, benzocaine, etomidate, sodium bicarbonate, and exposure to carbon dioxide…
I do not know what method they use in India but the concept is not revolutionary.
It is also referred to as “conditioning”.

As for related "induced meditative state” I think this would be more a of philosophical point of view rather than a biologic one. Is a mollusk capable of reaching a subconscious state is indeed the question!

If I may add, I am not sure about the exactitude of the report; that is in first place the understanding of the writer, and the accuracy of the translation.

Both may be culprits!
