Byssal re‐attachment behavior in the winged pearl oyster Pteria penguin in response to low salinity levels [PDF]
Journal of the World Aquaculture Society, 2021 The effect of low salinity levels on byssal re‐attachment behavior in Pteria penguin juveniles was observed in the laboratory. Juvenile pearl oysters were submerged in seawater blended to 8.0, 12.0, 16.0, 20.0, 24.0, 28.0, and 32.0 salinity levels for a ...

Effects of sea depths and sizes of winged pearl oysters (Pteria penguin) on pearl culture [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2003 Environmental aspects and biology of pearl oysters are the important conditions affecting pearl production. In order to obtain commercially valuable pearl from winged pearl oysters, Pteria penguin, three sizes (shell-length) of the oysters: small (130 ...

Diversified Biomineralization Roles of Pteria penguin Pearl Shell Lectins as Matrix Proteins [PDF]
International Journal of Molecular Sciences, 2021 Previously, we isolated jacalin-related lectins termed PPL2, PPL3 (PPL3A, 3B and 3C) and PPL4 from the mantle secretory fluid of Pteria penguin (Mabe) pearl shell. They showed the sequence homology with the plant lectin family, jacalin-related β-prism fold lectins (JRLs).
