Referring to fig. 1 to 6, the present embodiment provides a fish egg quantitative sample injector, which includes a counting plate 10, a bottom plate 20 and a handle assembly 30. A plurality of accommodating holes are formed in the counting plate 10, each accommodating hole can only accommodate one fish egg, and the bottom plate 20 is located below the counting plate 10. The counting plate 10 and the bottom plate 20 shown in fig. 1 to 6 are both circular, the diameter of the bottom plate 20 is larger than or equal to that of the counting plate 10, and the bottom plate 20 can cover all accommodating holes in the counting plate 10. Of course, the counting plate 10 and the base plate 20 may also have other shapes than the circular shape shown in the drawings, such as square, triangular, etc. Of course, instead of the base plate 20 shown in the figures being sized to cover the receiving holes used, the base plate 20 may be sized smaller than the counting plate 10 such that the base plate 20 covers only a portion of the receiving holes. The number of the accommodating holes in the counting plate 10 is set according to actual requirements, for example, 50 or 60 accommodating holes are formed in the counting plate, and each accommodating hole can accommodate only one fish egg. The handle assembly 30 is connected with the counting plate 10, and one end of the handle assembly 30 passes through the counting plate 10 and is connected with the bottom plate 20 so as to drive the bottom plate 20 to be close to or far away from the bottom surface of the counting plate 10.
When using this roe ration injector, operating handle subassembly 30 makes bottom plate 20 and counting board 10 separate, submerge bottom plate 20 and counting board 10 in the aquatic that is equipped with the roe, then operating handle subassembly 30 laminates the bottom surface to counting board 10 with bottom plate 20, at this moment, all contain an roe in every holding hole, then put into specific exposure container with this roe ration injector, operating handle subassembly 30 separates bottom plate 20 and counting board 10, the roe in the holding hole gets into in the exposure container, the application of sample of roe has been accomplished. Because the quantity of the accommodation hole that the bottom plate 20 laminating can cover on the count board 10 is fixed, the roe quantity of this roe ration application of sample ware of using at every turn to the application of sample in exposing the container is fixed, need not carry out artifical count and also need not calculate, saves time and manpower, can accomplish the ration application of sample of roe high-efficiently.
