0 has a double structure in which an inner frame 26 is combined inside an outer frame 25. The inner frame 26 is the bracket 2 of the outer frame 25.
7 (support member) and is detachable. The inner frame 26 has an upper net shelf 30, which will be described in detail later.
A fishing reef 32 made of netting is placed on the lower net shelf 31, and a fishing reef 32 made of net ring is placed on the lower net shelf 31.
An egg 33 to be hatched is placed on top of the egg.

続している。 A fresh water passage 34 and a lower passage 35 are separated between the outer frame 25 and the inner frame 26, and the fresh water passage 34 has a second
As shown in the figure, it is continuous over all four sides of the inner frame 26.

定してある。 The detailed structure of the inner frame 26 is as shown in FIG.
Two aluminum plates are formed into a substantially rectangular cylindrical shape by press working. The lower net shelf 31 made of resin trical net is provided on the lower end surface of the inner frame 26.
The lower net shelf 31 is connected to the flange portion 37 of the inner frame 26 and the frame 3.
8, and fixed with rivets 39.

る形状であればよい。 A tapered portion 40 (mounting portion) that is continuous over the entire circumference is formed in the vertically intermediate portion of the inner frame 26 . The peripheral portion 41 of the upper net shelf 30 is fitted into the tapered portion 40, so that the upper net shelf 30 is detachably provided. The upper net shelf 30 is made by punching a large number of holes 42 having a width B of 3 mm and a length L of about 20 to 25 mm, as shown in FIG. 6, in an aluminum plate with a thickness of about 1 mm. In addition, the upper net shelf 30
The mounting portion on which the net shelf 30 is placed is not limited to the tapered portion 40, and may be formed in a stepped shape or the like as long as it can place at least the upper net shelf 30 thereon.

ように流れる。 As shown in FIG. 7, which shows a cross-section taken from FIG. Width W of this wall board 43 (Fig. 2)
is not only one side 34a which is a part of the fresh water passage 34 from the water supply port 21, but also one side 34b to 34d (the second side).
(Figure) is also set so that clean water flows uniformly.
Therefore, fresh water flowing in from the water supply port 21 flows down the sides 34a to 34d, flows into the lower passage 35, and flows upward from the lower passage 35 above the inner frame 26.
下部通路３５には外枠２５の底面に突設した整

水の流量を増やし、一辺３４ａ〜３４ｄの各々か
ら内枠２６へ流れる清水の流量を一層均一化する
機能を備えている。 The lower passage 35 is provided with a rectifying plate 45 projecting from the bottom surface of the outer frame 25. This rectifying plate 45 reduces the flow rate of fresh water from the side 34a that is closest to the water supply port 21 and where fresh water easily flows, and reduces the flow rate of fresh water that flows to the inner frame 26 from the side 34c that is farthest from the water supply port 21 and where it is difficult for fresh water to flow. It has a function of increasing the flow rate of fresh water flowing from each of the sides 34a to 34d to the inner frame 26 to make it more uniform.
なお、整流板４５の代わりに第７図中で２点鎖
線で示す傾斜板状の整流板４６を設けることもで
きる。 Incidentally, instead of the current plate 45, an inclined current plate 46 shown by a two-dot chain line in FIG. 7 may be provided.
以上の構成では、上部網棚３０が枠がなくても
剛性のあるアルミ板製であるので、上部網棚３０

ス加工するだけでよい。 In the above configuration, since the upper net shelf 30 is made of aluminum plate which is rigid even without a frame, the upper net shelf 30
There is no need for a frame to hold it. Therefore, there is no need to provide an upper side plate 17 like the upper net shelf 16 shown in FIG. 8, and the inner frame 26 only needs to be formed by pressing one aluminum plate.

い。 The fresh water supplied from the water supply port 21 to the fresh water passage 34 is distributed approximately uniformly on one side 34a to 34d by the wall board 43, and descends to the lower passage 35 from all four sides around the inner frame 26. Furthermore, one side 34a near the water supply port 21 and the water supply port 21 on the rectifying plate 45 of the lower passage 35
The flow rate on one side 34c that is far from the other side is made uniform. Compared to the conventional system in which fresh water flows into the inner frame 11 only from the passage 12 as shown in FIG. 8, fresh water flows uniformly throughout the inner frame 26. Therefore, the fry in the upper side plate 17 on the lower net shelf 31 and the upper net shelf 3
The eggs 33 on the top of the egg 0 grow in the entire area inside the inner frame 26 while being washed by a flow of fresh water, and have a good hatching rate and growth rate.

３３がふ化した後の殻等を清掃する作業が容易で
ある。 The egg 33 on the tapered part 40 is also placed on the upper net shelf 3.
The hatching rate is good because they roll down onto the hole 42 of 0. When cleaning the upper net shelf 30, since the peripheral part 41 of the upper net shelf 30 is placed on the tapered part 40, the upper net shelf 30 can be easily removed, and the work of cleaning the shells etc. of the eggs 33 after hatching is easy. It's easy.
