PROBLEM TO BE SOLVED: To provide a marine aquaculture tray that can provide an environment being easy to be grown to one by one of all marine products such as bivalve being cultivated, enables the receiving work of the marine products such as the bivalve easily and in a short time, enables the take-out work of the marine products such as the received bivalve easily and in a short time, and prevents the received marine products such as the bivalve from falling out of a container due to a tidal current when being suspended in the seawater, and provide a marine aquaculture tray laminate laminating the same.SOLUTION: A box-type marine aquaculture tray 1 includes a net-like bottom wall 10 for marine aquaculture, which is suspended and used by a single body using a string or laminating multiple bodies and a sidewall 11. The marine aquaculture tray 1 is characterized by providing at least a set of string penetration holes 6 being vertically penetrated in the proximity position of the sidewall 11 being a symmetrical position to the center of the marine aquaculture tray 1 in a plan view. Also, a marine aquaculture tray laminate is provided which laminates the same.SELECTED DRAWING: Figure 1【課題】養殖しようとするすべての二枚貝等の水産物の一つ一つに生育しやすい環境を提供でき、二枚貝等の水産物の収容作業が容易で短時間にでき、収容された二枚貝等の水産物の取出し作業が容易で短時間にでき、海水等に垂下させたときに潮流により容器から収容中の二枚貝等の水産物が落下しない水産物養殖用トレー及びそれを積層した水産物養殖用トレー積層体を提供する。【解決手段】紐体を使用して、単体で、又は複数体を積層させて垂下させて使用する水産物養殖用の網状の底壁１０及び側壁１１を備えた箱型の水産物養殖用トレー１であって、平面視で前記水産物養殖用トレー１の中心に対する対称位置であって側壁１１近接位置に、少なくとも１組の上下方向に貫通した前記紐体貫通用孔６を設けたことを特徴とする水産物養殖用トレー１及びそれを積層した水産物養殖用トレー積層体。【選択図】図１
