This creation system discloses the device that one kind prevents cultured fishes from running away, and the periphery of one fish Ponds of what is arranged, and it includes a plurality of pedestals, a plurality of bottom fixed links, an anti-escape network and a plurality of floating elements. The periphery of a plurality of pedestal system setting one fish Ponds of what, a plurality of bottom fixed links are fixed between a plurality of pedestals of what respectively with the direction on parallel what ground. The bottom edge of one anti-escape network is connect with a plurality of bottom fixed links, and a plurality of floating elements then hang the top margin of what anti-escape network. By a plurality of floating elements, in waterflooding, anti-escape network is unfolded in buoyancy provided in what water, and then prevents cultured fishes from running away.本創作係揭露一種防止養殖魚類脫逃之裝置，係設置於一魚塭之外圍，其包含複數個基座、複數個底部固定桿、一防逃網、與複數個漂浮元件。複數個基座係設置於一魚塭之外圍，複數個底部固定桿以平行於地面之方向分別固定於複數個基座之間。一防逃網之底邊與複數個底部固定桿連接，複數個漂浮元件則懸掛於防逃網之頂邊。藉由複數個漂浮元件在淹水時於水中所提供的浮力展開防逃網，進而防止養殖魚類脫逃。
