Pearl culture is a crucial component of the aquaculture industry, with the quality and survival rates of cultured pearls being the key determinants of success. This study explores the potential of Poly-D-lysine (PDL) coated nuclei to enhance pearl quality and mussel survival rates during cultivation. A comparative analysis was conducted between normal uncoated nuclei and PDL-coated nuclei to evaluate the benefits of nucleus surface modification. The results indicate that PDL-coated nuclei significantly improve both pearl quality and mussel survival rates. Pearls produced with PDL-coated nuclei exhibit superior attributes, including enhanced lustre, intensified colouration and smoother surfaces. Moreover, the survival rate of mussels in the PDL-coated nucleus group was notably higher, underscoring the coating's positive impact on mussel viability during the culture process. The PDL coating also promotes more effective nucleation, leading to a higher rate of successful pearl formation. This study provides valuable insights into improving pearl cultivation practices, highlighting the potential of PDL-coated nuclei to elevate the efficiency, sustainability, and overall quality of pearl production. Future investigations should focus on clarifying the mechanisms underlying these effects and refining surface modification techniques to further advance the field of pearl aquaculture.
