Progress on Pearl Production from Hyriopsis Cumingii
An overview on the production of composite pearl,non-nucleated pearl and nucleated pearl of freshwater pearl mussel Hyriopsis cumingii was presented,including the types and characteristics of model nucleus,the choosing of host pearl mussel,and the operation requirements of nucleus implantation techniques for composition pearls culture.The production process of non-nucleated pearls and nucleated pearls produced in the mantle tissue of pearl mussel,the choosing of donor mussel and host pearl mussel,as well as the surgical implantation for the nucleated pearls production in the visceral mass were covered in this article.The results suggested that the research on the culture of large and high-quality round pearls from pearl mussel Hyriopsis cumingii by nucleus implantation in the visceral mass should be conducted.
