CATDOLL : CATDOLL: What are the various conditions for growing oysters?

Although the shells of oysters are very strong, there are still many cunning "pirates" and "murderers" in the ocean who can break the shells of oysters. The natural enemies of oysters mainly include fish, shellfish, echinoderms, crabs, sessile organisms and birds.

Among the natural enemies of oysters, fish mainly include carnivorous fish such as pufferfish, black sea bream, sea crucian carp and rays. Rays can use their strong teeth to bite through the shells of oysters and then eat them; shellfish mainly include carnivorous snails such as red snails, litchi snails, oyster snails, fragrant snails and jade snails; echinoderms mainly include petrels and starfish. When starfish prey on oysters, they often climb onto the shells of oysters, use their powerful tentacles to pull open the oyster shells with force, and then eat a full meal without mercy; the crabs that harm oysters mainly include serrata mud crabs, which can use their powerful chelicerae to break and dig into the oyster shells and then eat the oysters; and sessile organisms mainly include barnacles, purple mussels, tunicates, bryozoans, etc., which mainly compete with oysters for fixation, oxygen and food; birds include oystercatchers, etc.
