The utility model belongs to the technical field of fish feeding devices, provides a feeder capable of reducing specification difference of micropterus salmoides, and aims to solve the problem of inconvenience in classified feeding of fishes with different sizes. The feeder comprises a mounting frame, a first handrail is fixedly connected to the mounting frame, and a net rack is fixedly connected to the partition plate. According to the fish feeding device, through the arranged fixing ring, in order to avoid that small fishes cannot grab food during fish school feeding, pull rods on the two sides are pulled to drive a connecting plate to move, the connecting plate can extrude a spring during moving, meanwhile, clamping blocks on the pull rods are separated from a mounting frame, and after the fixing ring is not hindered, the fixing ring can be rotated to rotate, so that the small fishes can be conveniently fed; a second handrail on a fixing ring operates and cooperates with a first handrail on a mounting fram
