The invention discloses an automatic feeding device capable of effectively reducing
eutrophication of an
aquaculture environment. The automatic feeding device comprises a feeding cavity, a middle
pipe, a storage cavity and a floating net, wherein a floating
air cushion is fixedly installed at the bottom of the feeding cavity, a cover plate is movably installed at the top of the feeding cavity, themiddle
pipe is fixed to the middle of the interior of the feeding cavity in a penetrating mode, the upper end of a vertical
pipe is fixed to the lower end of the middle pipe, a forked thin pipe is fixed to the lower end of the vertical pipe in a penetrating mode, a pull shaft is movably installed in the middle pipe, a
fishing line pull
rope is fixed to the bottom of the pull shaft, and the feeding cavity and the floating
air cushion are fixedly installed in the floating net. According to the automatic feeding device capable of effectively reducing the
eutrophication of the
aquaculture environment, through foraging movement of fishes, intermittent small-amount and multi-time
casting of baits in a culture pond is achieved, the feeding amount of the baits at a time and human-assisted labor consumption are reduced, and the problems of use waste of the baits and
eutrophication in the culture pond are prevented.
