Eco-Friendly Pearl Farming at Margaret Jewelry: The Fish-Oyster Symbiotic System

Recent years, we have embraced the fish-oyster symbiotic system as a cornerstone of our environmental protection efforts in pearl farming.


This innovative approach was developed to address the eutrophication caused by the rapid expansion of pearl farming operations in the 2010s. By integrating poultry farming, algae, oysters, and fish into a cohesive cycle, our method provides natural feed for oysters and eliminates the need for external nutrients and chemicals like antibiotics, resulting in a healthier farming environment.

Within this system, fish waste promotes the growth of algae, which in turn serves as a natural food source for the pearl oysters. This nutrient cycle reduces the dependency on chemical additives, making the entire process more environmentally friendly. Furthermore, the symbiotic relationship between fish and oysters enhances the health of the aquatic ecosystem and promotes biodiversity. This diverse ecosystem helps maintain water stability and provides a more natural growth environment for the oysters​

Additionally, waste utilization is a key component of this system. Ducks and fish can be harvested for food, while oyster meat and shells are repurposed as feed and fertilizer, returning nutrients to the local soil and water. The shells can also be processed into various products, such as crafts and mosaics. This approach not only reduces waste accumulation but also minimizes environmental pollution. It is an eco-friendly method that improves both the quality and yield of pearls, representing a win-win for both people and nature.

By implementing these practices, Margaret Jewelry has successfully addressed the environmental challenges posed by traditional pearl farming methods, creating a sustainable model that benefits the ecosystem and the pearl farming industry​!
