specific Embodiment approach 1

[0015] Specific Embodiment 1: In this embodiment, a device for placing fertilized eggs of whitebait on a large water surface under ice includes a fertilized egg storage bucket 3, an external power supply, a motor 7 and a tablet computer 16; the top of the fertilized egg storage bucket 3 A thermal insulation cover 1 is provided, a support 8 is provided at the bottom of the fertilized egg storage bucket 3, a temperature display 4, an external power supply and a motor 7 are arranged on the outer wall of the fertilized egg storage bucket 3, and the water outlet at the bottom of the fertilized egg storage bucket 3 is connected with Automatic telescopic delivery tube 13, the water outlet is provided with sealing plug 10, the end of automatic telescopic delivery tube 13 is provided with temperature probe 15, and the outer tube wall at the end of automatic telescopic delivery tube 13 is provided with lamp underwater camera 14, fertilized eggs The inside of the storage barrel 3 is provi...

specific Embodiment approach 2

[0020] Embodiment 2: This embodiment differs from Embodiment 1 in that: the outer surface of the rotating part of the rotating screw rod 2 is provided with bird feathers. Bird feathers can ensure uniform density of fertilized eggs of big whitebait, and reduce damage to fertilized eggs of big whitebait.

[0021] Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0022] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is: the external power supply and the motor 7 are provided with a thermal insulation box 5 .

[0023] Other steps are the same as those in Embodiment 1 or 2.

Abstract

A device for dropping fertilized eggs of whitebait under ice on a large water surface and a method for using the same, which relate to the technical field of artificial proliferation of fertilized eggs of whitebait. The purpose of the present invention is to solve the problems of large ice-breaking area, long operation time and low hatching rate of fertilized eggs due to the high density of fertilized eggs in the existing way of placing fertilized eggs of big whitebait under ice on large water surface. Method: Put the automatic telescopic delivery tube in the water through the opening, control the extension of the automatic telescopic delivery tube, control the rotation of the screw rod and the automatic telescopic delivery tube through the motor, and open the sealing plug at the water outlet of the fertilized egg storage bucket, and release it into the water Fertilized eggs of large whitebait, and observe the release density of fertilized eggs of large whitebait underwater through a tablet computer. When the release density reaches the requirement, close the sealing plug, control the automatic retractable release tube to shrink to the shortest length and take it out of the water. The invention can obtain a device for putting fertilized eggs of large whitebait under ice on a large water surface and a using method thereof.

Description

technical field [0001] The invention relates to the technical field of artificial multiplication of fertilized eggs of whitebait, in particular to a device for placing fertilized eggs of whitebait under ice on a large water surface and a method for using the same. Background technique [0002] Whitebait (Protosalanx hyalocranius) is the largest individual fish in the Antheraceae family and the genus Protosalanx. It has high protein content, low fat content, and various trace elements. The value and economic value are quite high, and it is an excellent species for transplanting and multiplying on large water surfaces such as lakes and reservoirs. Whitebait is a cold-temperate fish, which spawns and breeds under the ice in Northeast China in December. At present, the transplantation of large whitebait in large water surfaces in Northeast China mainly adopts the method of breaking the ice in winter and releasing fertilized eggs. Taking Heilongjiang Province as an example, the...
