The present invention relates to a combination boat wherein a lower hull and an upper hull are made of FRP, and an air tube is installed in an edge and, more specifically, to a fishroom drain of a combination boat, which is installed in the rear inside the combination boat. According to the present invention, water in a fishroom can be automatically controlled in case the combination boat is sailed and stopped. According to the present invention, a fishroom drain is installed on both sides of the rear of the combination boat, wherein, when stopping, the combination boat goes under by a self-load, so the drain is immersed in seawater and seawater flows into a fishroom, and when sailing, a hull of the combination boat is raised by a sailing speed of a ship for seawater in the fishroom to be drained while leaving minimum water for survial of fish. Thus, in accordance with seawater flowing into or discharged from the fishroom, a load can be lightened to save fuel when sailing.
