Then he artificially creates the conditions that cause oysters to spawn. One billion oyster babies are produced in these tanks every year. When the oysters get to be about a quarter inch long, they're placed outside and up well er tanks. After about two months of feeding staff check on the size of the oysters. We'll take these oysters here that are larger and they'll go in the cage to go overboard. After six months, the cages are removed from the water and the oysters are brought to a separator. If they are not big enough to sell, They go back in the water. Oysters can take around 1-2 years to go from hatchery to market.
