The invention provides a mobile onboard cabin raising management system. The system comprises a ship body, a fish-farming water cabin, a mobile platform and a circular track arranged at the periphery of the top of the fish-farming water cabin; the mobile platform is connected to the circular track and can move along the circular track, the ship body is provided with a watertight transverse bulkhead, the fish-farming water cabin is divided into multiple cabins by the watertight transverse bulkhead, and the watertight transverse bulkhead is provided with an automatic watertight door for the mobile platform to pass through; the circular track disconnects at the automatic watertight door portion, the disconnecting spacing is bigger than the thickness of the automatic watertight door, and the circular track and the transverse bulkhead are 40-50 mm apart front and rear. According to the mobile onboard cabin raising management system, the channel problem of onboard managers and fish feed in and out of carts is solved, and the live-action monitoring problem of the onboard managers is solved.
