[0032] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0033] Example:

[0034] As attached Figure 1 To be continued Figure 6 As shown:

[0035] This utility model provides a rapid screening device for aquatic fish fry, comprising: a screening shell 1; movable handles 2 on the left and right sides of the screening shell 1; a small-hole screen 6 inside the screening shell 1; circular handles 8 on the left and right sides above the small-hole screen 6; a large-hole screen 5 inside the small-hole screen 6; and circular handles 8 on the front and rear sides of the large-hole screen 5.

[0036] Among them, such as Figure 4 and Figure 5 As shown, the small-hole screen 6 has a surrounding plate 11 around its opening, and a fixing plate 7 on the left and right sides of the surrounding plate 11. A circular handle 8 is provided above the fixing plate 7. The large-hole screen 5 has a surrounding plate 11 around its opening, and a fixing plate 7 is provided on the front and back sides of the surrounding plate 11. A circular handle 8 is provided above the fixing plate 7, which makes it easy to lift the large-hole screen 5 and the small-hole screen 6 to screen the fish fry.

[0037] Among them, such as Figure 1 and Figure 6 As shown, an isolation baffle 4 covers the top of the screening shell 1, the small-hole screen 6, and the large-hole screen 5. The isolation baffle 4 has a fish fry inlet 10 in the middle and an opening 9 around the perimeter of the isolation baffle 4. The circular handles 8 on the small-hole screen 6 and the large-hole screen 5 protrude from the opening 9 to prevent the fish fry from falling directly into the small-hole screen 6 or the screening shell 1, which would cause errors in the screening of the fish fry.

[0038] Among them, such as Figure 3 As shown, a fixing groove 3 is provided above the movable handle 2 of the screening shell 1, and the fixing plate 7 of the small hole screen 6 is stuck in the fixing groove 3, which is conducive to fixing the position of the screen.
