摘要

PURPOSE: A rack type oyster culture system, and method for producing and harvesting non-attached individual seeds are provided to simplify the farming process of oyster and the work of installation, and to solve the deterioration problem and the contamination problem of a fishing ground. CONSTITUTION: An oyster culture system is comprised of a bag type net(3) for receiving seeds, and a frame body(9) spaced from a bottom surface by a leg part(7). The net is carried by a longitudinally arranged support rod(5) and a transversally arranged support rod(5'). The frame body comprises a transverse strut(11), and a longitudinal rack(13) installed at right angles relative to the strut. After installing an oyster seeds farming facility in a tideland, the seeds are harvested from black polypropylene as a seeds farming substrate. The harvested non-attached individual seeds are received in the net. For harvesting the seeds, the period of 30 to 50 days is required.
