Abstract: A method for the cultchless cultivation of mollusks comprises placing the mollusks in an elongate bag of mesh material, which is preferably about 100 feet long. The bag has a longitudinal slit therein for providing access to the bag. The bag is suspended under tension in an underwater off-bottom location whereby the slit is maintained in a closed position by the tension. The invention also includes apparatus for raising the bag into an elevated position above the water for husbandry and harvesting purposes. In one embodiment, the apparatus comprises a raft provided with a pair of spiked rollers thereon for moving the bag along the top of the raft.
