Oysters, commonly known as oysters, oysters and so on. Belongs to mollusks, bivalves and Pinctada. It is the largest cultured shellfish in the world, one of the important marine biological resources available to human beings, and a globally distributed species.
Oysters are mostly hermaphroditic, but there are also hermaphroditics, and gender conversion often occurs between them. In the process of oyster breeding, mature sperm eggs are discharged from their parents, fertilized, hatched and developed in seawater, and fixed on rocks and other objects after a period of floating life. Most oysters, such as pleated oysters, long oysters and near-river oysters, belong to this culture mode. ?
The breeding period of oysters varies from species to species. Even the same kind of oyster has different breeding periods due to different living areas. Generally speaking, the breeding season of oysters is mostly from June to August. According to statistics, a female oyster can lay as many as 400 million eggs in a breeding season, but the gonads of oysters are only fully developed in the breeding season.
