The way of spawning is: 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 oysters, oysters and riverside oysters belong to this culture mode. Now, they will enter the real "society". Workers will transport oysters to further sea areas and leave them in the mud on the seabed for about half a year. After half a year's natural growth, the workers sailed to harvest.

In the deep water, set a fixed grid frame in a calm place. Most oyster seedlings are fixed on the grid frame with shells and cement tiles in series, and each string is 1 ~ 1.5m long. Pay attention to the density should not be too high to prevent bottoming out, so as not to be attacked by natural enemies of benthic organisms. Due to the limited suitable growth conditions, its number is less than other varieties. Therefore, the economic price of oysters is generally higher. Oysters can not only be eaten raw, but also have the effect of tonifying kidney and caring skin. You can also bake it and eat it with fans. But people with skin diseases and spleen and stomach weakness should eat less.

The cultured oyster meat is fresh, tender, fat, refreshing, smooth, sweet, crisp and slag-free, and it is the only ecological seafood product that does not need artificial feeding. There are usually three ways to cultivate oysters in Zhanjiang: 1. Hanging rope culture: it is a convenient way to cultivate oysters by connecting the shellfish ropes that fix oyster seedlings in series. Materials are ropes and floating objects, which are generally suitable for farming in relatively open sea areas. Longline fishing has strong wind and wave resistance and is also suitable for offshore farming.

Manufacture, treating and place that attachment base, and taking the young shellfish out of the pond; The operation process of semi-artificial seedling collection includes: selection of seedling collection field, examination of gonad development of parent shellfish, collection and investigation of planktonic larvae, production, treatment and release of attachment base. Fourth, there are many ways to breed oysters. Similarly, erect the base column first, and then erect a long square on it with bamboo pipes or plastic pipes. Oyster strings are hung vertically, perpendicular to the water flow, which increases the feeding opportunities. The depth of seawater in the culture area is deeper than that in the flat hanging type, mostly in the inner bay and tidal ditch.
