The invention provides a movable platform for a shipborne culturing-in-bin management system. The movable platform comprises a centralized control module and at least one feeding modules, wherein the centralized control module is hoisted on a railway at the top of a culturing bin. The centralized control module comprises a controller, a positioning sensor, a suspension support, a ship body and a driving module, and the driving module is hoisted on the railway. Each feeding module comprises a suspension support, a material bin, a discharge device and a driving module hoisted on the railway. The suspension supports are arranged below the driving modules, the material bin is connected to the position below the corresponding suspension support, and the discharge device is arranged at the bottom of the material bin. By arranging the movable platform in a water bin for fish culturing, the problems of live-action monitoring and fish feeding of administrative staff on a ship are solved.
