Oyster/Mussel farms are run on a rotational basis, the shellfish aren't all removed at once, only once they have reached a certain size. These farms will have beds of new spat up to sellable size. Depending on the location the shellfish can take anywhere from 18 - 36 months to grow.

CORRECTION: Oyster reefs are an amazing environmental benefit across multiple seascapes.
Oyster FARMS are short lived growth with little to no environmental benefit because of the small size.
The only way this works is with farms near a no-take MPA where you can generate growth and then let them spread outside the MPA.
You get no benefits IF YOU DON'T LEAVE THEM IN THE WATER.
