Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: a fry hatching device for freshwater viscous spawn fishes comprises a cement culture pond 6, wherein a water inlet pipe 1 is fixedly connected to the rear of the upper end of one side of the cement culture pond 6, the water inlet pipe is externally connected with a reservoir, a water outlet pipe 9 is fixedly connected to the front of the lower end of the other side of the cement culture pond 6, the water outlet pipe is externally connected with a drainage ditch, a dense mesh net box is arranged in the drainage ditch, a micropore oxygenation pipe 11 is arranged at the bottom of the cement culture pond 6, the micropore oxygenation pipe 11 is externally connected with an air compressor 12, a separation pier 7 is arranged at the bottom of the cement culture pond 6, a hollowed-out bamboo bed 8 is fixedly connected to the upper surface of the separation pier 7, a willow root 5 is placed on the upper surface of the hollowed-out bamboo bed 8, tiles 13 are placed on the upper surface of the willow root 5, a PVC water pouring pipe 3 is arranged above the willow root 5, a PVC water pouring, the upper surface of the PVC water spray pipe 3 is fixedly connected with a suspension wire 4, and the suspension wire 4 is fixedly connected with a roof.

In order to facilitate the heat preservation of the pond water and the collection of the fry, in this embodiment, preferably, the depth of the cement culture pond 6 is one hundred twenty centimeters, and the slope of the cement culture pond 6 is one-fifth per mille.

In order to facilitate smooth water flow and collect fish fries, in this embodiment, preferably, one end of the drain pipe 9 is fixedly connected with a drainage ditch, the bottom surface of the drainage ditch is fifty centimeters lower than the drain pipe 9, and a dense mesh net cage is arranged in the drainage ditch.
