This creation system is a kind of escape-preventing structure of breeding trough, the escape-preventing structure by it is plural can mutually overlapped that protection edge strips are formed, and the top surface of the surrounding cell wall of breeding trough is set, wherein, each protection edge strips have an overlapping what cell wall top surface and towards the protective plate of protrusion is enclosed in breeding trough, one by being extended downwardly on the outside of protective plate for the fixinig plate of the fixed what cultivation groove groove wall of protective plate and at least one setting in protective plate side for overlapped between protective plate and protective plate bonding jumper. By above structure, it is enclosed in protective plate protrusion what breeding trough, it can prevent cultivation fish from only being climbed such as sea eel by cell wall upwards and jumping out breeding trough, and protection edge strips are modularity specification, it can be assembled according to the size of breeding trough, there is many advantages, such as easy to manufacture, easy to assembly and reduction manufacturing cost.本創作係為一種養殖槽之防逃結構，該防逃結構係由複數能相互搭接的防護邊條所組成，並設置在養殖槽之四周槽壁的頂面，其中，每一防護邊條具有一疊合於槽壁頂面並朝向養殖槽內圍凸出的防護板、一由防護板外側向下延伸以供防護板固定於養殖槽槽壁的固定片、以及至少一設置在防護板側邊以供防護板與防護板之間搭接的搭接片。藉由上述結構，防護板凸出於養殖槽的內圍，可以防止養殖魚隻例如鰻魚等由槽壁向上攀爬而跳出養殖槽，且防護邊條為模組化規格，能依照養殖槽的尺寸組裝，具有容易製造、組裝方便、以及降低製造成本等諸多優點。
