[0033] like Figure 1-6 As shown, a rainbow trout hatching barrel provided in this embodiment includes: a barrel body 1, a grate 2, a water injection pipe column 3 and a funnel 4; the barrel body 1 is open at the top; the grate 2 is horizontally placed in the barrel body 1, dividing the barrel body 1 into two upper and lower spaces; a first through hole 21 is arranged in the middle of the grate 2, and the water injection pipe column 3 vertically passes through the first through hole 21 of the grate 2, and a plurality of second through holes 22 are evenly arranged on the grate 2, and the grate 2 is used for laying rainbow trout eggs, and the aperture of the second through holes 22 is smaller than the diameter of the rainbow trout eggs; the height of the water injection pipe column 3 is higher than the height of the barrel body 1; the funnel 4 is inserted into the top opening of the water injection pipe column 3.

[0034] The components of the above-mentioned rainbow trout hatching bucket are detachable for easy cleaning. When in use, the components are assembled according to the above-mentioned matching relationship. The funnel 4 can be inserted into the water injection column 3 after the other parts of the hatching bucket are assembled. Figure 4 As shown, a hand-held end 41 can be provided thereon to facilitate hand-held insertion.

[0035] When the rainbow trout eggs are hatched, the rainbow trout eggs are laid on the grate 2, and multiple layers can be laid. For a grate with a diameter of about 30 cm, about 30,000 eggs can be laid after multiple layers are laid. Then, flowing water is slowly flowed into the funnel 4, and then the flowing water can pass through the funnel 4 and the water injection column 3 in sequence, flow out from the bottom of the water injection column 3, and then pass through the second through hole 22 on the grate 2, and finally flow out from the top opening of the barrel 1.

[0036] Through this flowing water circulation method, the flowing water required for the hatching of rainbow trout eggs is guaranteed, and the flowing water will not directly impact the rainbow trout eggs, which greatly improves the hatching efficiency of the eggs. The eggs can be laid in multiple layers on the grate, which can be suitable for the hatching of a large number of rainbow trout eggs.

[0037] Cooperate Figure 3 As shown, in order to prevent the fish eggs on the grate 2 from being washed away by water, the vertical height of the grate 2 from the bottom of the barrel body 1 is preferably about one third of the height of the barrel body 1.
