The present invention provides a foothold support device for a fish farming cage, which is fabricated by connecting and assembling pipe type pipe props (2) having a predetermined length so that the pipe type props are fused and combined to each other through thermal fusion, thereby improving workability, wherein the pipe props (2) are formed in a pipe body having penetration holes (6) through which both ends of each of the pipe props (2) are accommodated, and an electric heating wiring (7) for generating heat by receiving electricity from the outside is formed on the inner circumferential surface of the pipe body. Here, the foothold support device for a fish farming cage is assembled through connection sockets (8) which connect the pipe props (2) by being thermally fused with and fixed to ends of the pipe props (2). |
