The invention discloses a practical and efficient fish transfer device. The practical and efficient fish transfer device comprises a transport tank, and the lateral side of the transport tank is connected with a filter. A water inlet
pipe above the filter is connected with a water pump inlet
pipe arranged on the lateral side of the transport tank. A water outlet of a water pump outlet
pipe is arranged above the transport tank. The lower side of the filter is communicated with a
sedimentation chamber at the bottom of the transport tank through a
water pipe, and a drain pipe is connected to thebottom of the
sedimentation chamber. A funnel is connected above the lateral side of the transport tank, and an oblique
discharge pipe arranged on the upper portion of the transport tank is connectedbelow the funnel. A separating net and a dispersing ball are placed in the transport tank. A plurality of rotating shafts are arranged in the middle of the separating net. A sealing chamber is formedin the dispersing ball through
silica gel, and a secondary light-emitting tube is placed in the sealing chamber. The practical and efficient fish transfer device has the advantages that the
oxygen capacity in a
transport water body can be increased without an aerator,
ammonia nitrogen and other harmful substances in the
water body can be filtered out, fishes have
high activity and good quality, and sediments in water are easy to collect.
