This creative department provides a breeding system, especially a multi-layer net rack with multiple layers of breeding nets in the breeding tank. Placing shellfish on the breeding net can greatly increase the breeding area and increase production. When the shellfish grows and harvests , The net rack can be lifted off the breeding barrel for harvesting treatment to save artificial breeding equipment.本創作係提供一種養殖系統，尤指一種在養殖桶內設置具有多層養殖網的多層網架，將貝類放置在養殖網上養殖，可大幅增加養殖面積，以提高產量，當貝類成長採收時，可將網架吊離養殖桶作採收處理，以節省人工的養殖裝置。
