The present invention relates to a donut-shaped water tank for an eel larva mass production having an integrated type water supply/drain pipe. The provided donut-shaped water tank is equipped with a feeding water rotation supply spray device which circulates at an appropriate flow rate so that larvae meet liquid feed in the tank which has a large diameter capable of accommodating the larvae in large quantities. Thus, the present invention reduces labor costs and prevents the mortality of larva by not only evenly mixing the liquid feed without forming a blind spot which is formed in an existing water tank when spraying feeding water or air but also automatically circulating the liquid feed in the water tank by controlling a feeding water spray device and the rotation speed of a sub motor for mixing the liquid feed. Also, the present invention can easily disassemble and assemble each component of a water tank main body, drain equipment, and the feeding water spray device which compose the water tank.
