Glutamate induces larval settlement of the pacific oyster Crassostrea gigas

Abstract: The settlement of bivalve larvae is a complex process influenced by a combination of environmental, biological, and chemical factors, which is crucial for the development of the bivalve seedling industry. This study investigates the potential of glutamate (Glu) at various concentrations to induce settlement in Pacific oyster ( Crassostrea gigas ) mid-stage umbo larvae. The findings reveal that treating mid-stage umbo larvae with 10 −4 M Glu for 6 h enhances growth and survival rates, significantly promotes the formation of eye spots, and accelerates settlement. Glu can effectively induce larval settlement, leading to the development of neural structures such as eye spots. This research confirms the efficacy of Glu as a larval settlement inducer in oysters, offering novel strategies for oyster seed production.
