ABSTRACT:
A method is disclosed in which cultchless young oysters of a selected size taken from seed stock are placed in a first set of foraminous cribs and the first set of foraminous cribs are then placed on a shelf within an open top receptacle where the young oysters are protectively housed within the receptacle intermediate the top and bottom of the receptacle. Immature oysters of a larger size than the oysters placed in the first set of cribs are placed in a second set of foraminous cribs and the second set of foraminous cribs are placed across the open top of the receptacle above the first set of cribs. The second set of cribs are lashed to the top of the receptacle, whereupon the receptacle with its oyster containing cribs supported thereon are lowered to the bottom of a body of water where it is allowed to remain for a predetermined oyster growth period. The receptacle and trays may be raised periodically for inspection, and for culling from the second set of cribs the mature oysters, and for culling from the first set of cribs immature oysters above a predetermined size which are then placed in the second set of cribs where they are allowed to reach maturity. The apparatus of this invention comprises the receptacle described above in subcombination and in combination with the foraminous cribs.
