Question

Who stands first in the world for Pearl production?
A) India
B) China
C) Korea
D) Japan

Answer 1

Hint: Cultured pearls are produced by pearl oysters as a result of delicate techniques developed by scientists over a few years. The standard of pearls with relevancy their shape and colour, which are important factors in terms of their market price, don't seem to be only influenced by external environmental factors, but also by the inherited capabilities of individual oysters.

Complete answer:
The pearl is thought to be the queen of jewels, and has been used for adornment and as an emblem of fabric wealth throughout human history. Pearls are formed by the secretion of nacre from epidermal cells within mollusc mantle tissue.

However, utilization of this process for classy pearl production now supports industries in additional than 30 countries including China, Japan, Australia, Indonesia, possession, Philippines, Cook Islands, Thailand, Malaysia, India, Sri Lanka, Myanmar and Mexico, of which China has the most important production. The typical annual output of Chinese pearls was 3540 tonnes valued at 15 million USD. This output accounted for over 98% of world cultured pearl output, of which freshwater pearls accounted for 99.5%.
Japan has been the world’s major marine pearl producer for over a century, and has developed advanced technology in culture and pearl production. Within the past decade, the typical annual value of marine cultured pearl production in Japan was 127 million USD, accounting for 51.6% of worldwide pearl output value.

Average annual production of marine cultured pearls was 23 t in Japan, 18.6 t in China and 12.9 t in possession. Chinese pearl production is typified by a high-yield, low-value industry structure. Overall, global pearl production fell by 60% while output value fell by 39% over the past decade. Compared with other aquaculture sectors, pearl production features a complex process and a comparatively long farming cycle which make it economically risky.

Therefore, the correct answer is option ‘D’, Japan.

Note:The culturing process usually takes several years. Mussels must reach a mature age, which might take up to three years, and only then will be implanted or naturally receive an irritant. Once the irritant is in situ, it can take up to a different 3 years for the pearl to succeed in its full size and nacre thickness. Around 5% of produced pearls are of the right quality for jewellery making, yet a pearl farmer can figure on spending over $100 for each oyster that's farmed.
