Abstract

The invention discloses a feeding device and method for silvery pomfret in the East China Sea, and aims to overcome the defects that in the silvery pomfret breeding process, the utilization rate of baits is low, and the baits sink to the bottom of a pond for a long time to pollute the breeding environment. The feeding device comprises a feeding barrel, a plurality of bait outlet nozzles are arranged at the lower portion of the feeding barrel, one-way cover pieces are installed at the opening ends of the bait outlet nozzles, a piston assembly is installed in the feeding barrel, a bait storage barrel, a lifting base and a driving assembly are installed on the upper portion of the feeding barrel, the lifting base is connected with the piston assembly, a material squeezing plug is installed inthe bait storage barrel, and a piston rod is connected betwene the material squeezing plug and the lifting base; a material extruding cavity is formed between the position, below the piston assembly,in the feeding barrel and the bottom of the feeding barrel, and a feeding pipe is connected between the piston assembly and a discharging hole; the lifting base moves upwards, the material squeezingplug pushes the baits to enable the baits to be injected into the material squeezing chamber through the feeding pipe, and meanwhile the lifting base drives the piston assembly to move upwards to enable the material squeezing chamber to be enlarged; and the lifting base moves downwards to drive the piston assembly to move downwards to extrude the baits in the material squeezing chamber out throughthe bait outlet nozzles.
