Producing high-quality pearls demands a long-term vision, sound environmental stewardship and responsible farming practices. Pearl oysters are remarkably sensitive organisms. Following the grafting procedure oysters are returned to thriving waters to offer them optimum growth conditions. The healthier an oyster is the less likely it will reject the nucleus, be affected by diseases or mortalities, or be affected by stress, and the more likely it will produce a higher quality cultured pearl. The environment plays a fundamental role in oyster health but so do pearl farming practices such as the stocking densities of oysters.
Oysters may be protected by nets or baskets to reduce predation. Furthermore, pearl oysters are regularly cleaned in order to remove biofouling (faunal and floral overgrowth on the oyster shell), which can hinder healthy oyster growth and pearl production.
