Oysters are what are known as filter feeders; they filter microscopic organisms out of the water. They therefore do not have to attract prey. The prey is always there, in the water, carried by currents, and oblivious to its fate.

Oysters and Oyster Borers have a predator-prey relationship. Oyster Borers are a type of marine snail that feeds on oysters by boring into their shells, weakening and eventually killing the oysters. This relationship can have negative impacts on oyster populations and can disrupt marine ecosystems.
to attract their prey so they go closer and then they eat their prey
Some insects can use sound to attract prey. For example, certain insects like crickets and cicadas produce loud, distinct sounds to attract mates or communicate with each other. These sounds can also inadvertently attract prey that may be drawn to the vibrations or noise.
Snakes use various methods to attract their prey, such as ambush hunting by remaining still and camouflaged until prey comes close enough to strike, or using pheromones to lure prey towards them. Some snakes may also use movement or vibrations to mimic prey or create a visual distraction that draws prey closer.
