The present invention is an improved carcass comprising a shelf, and a plurality of floating buckets are arranged on the top of the shelf. The modified carcass is used for breeding oysters, and the improved carcass is placed in water, and the floating buckets can be placed in water. Floating on the water surface, the shelves under the floating buckets are submerged under the water surface, and the oyster seedlings can be tied to the shelf. Since the floating buckets are arranged on the top of the shelf, the shelf can be completely submerged under the water surface. The shelf is not directly slammed and impacted by the waves, and the shelf is permeable to water in the water to slow down the impact of the waves, the shelf is not easily damaged and the service life is improved, and the use of the floating bucket is more resistant to wave impact and It is not easy to produce debris, in addition to improving the service life, it also meets environmental protection requirements and protects the ecological environment.本創作係一種改良型筏體，其包含一架子，並於該架子的頂部設置複數浮桶，該改良型筏體用於養殖牡蠣時，該改良型筏體放置於水中，該些浮桶可漂浮於水面上，位於該些浮桶下方的架子則沒入水面下，牡蠣苗可綁設於該架子，由於該些浮桶設於該架子的頂部，讓該架子可完全沒入水面下，使該架子不會受到波浪直接的拍打、衝擊，且該架子在水中可透過水減緩波浪的衝擊力，使架子不易損壞並提高使用壽命，以及所述浮桶的採用，更能抵抗波浪衝擊且不易產生碎屑，除了可提高使用壽命之外，還符合環保需求並保護生態環境。
