The outer cylinder of the tank effectively protects the vertebral body and the drainage branch pipe from damage, and does not require a bottom bracket, which is convenient to use and carry;

2. The water tank adopts a multi-level shelf design, and the breeding shelf can be increased or decreased according to actual needs, which improves the space utilization efficiency of the water tank;

3. The integrated design of the shelf and the central movable jacket facilitates the disassembly of the shelf;

4. Each layer of breeding shelf is composed of four movable shelves of equal size, and a handle is installed on each of the two symmetrical movable shelves, which is convenient for cleaning the lower shelf;

5. The sink is equipped with a central drainage pipe, and many drainage holes are set on the drainage pipe to prevent shellfish from escaping while realizing efficient discharge of breeding wastewater and residual bait;

6. A liquid flow meter is installed at the water inlet to realize accurate monitoring of the aquaculture water flow;

7. The breeding shelf is made of transparent glass fiber reinforced plastic material, which is strong and durable, and it is convenient to observe the breeding situation of shellfish on each floor.

Fig. 2 is a schematic diagram of the shelf structure of the present invention.

In the figure: aquaculture tank 1, water inlet 2, liquid flow meter 3, movable shelf 4, handle 5, movable jacket 6, central drain pipe 7, drain hole 8, tank bottom 9, extended drain outlet 10, drain branch pipe 11 .

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Figures 1 and 2, a shellfish test breeding tank includes a breeding tank 1, a water inlet 2, a liquid flow meter 3, a movable shelf 4, a handle 5, a movable jacket 6, a central drain pipe 7, and a drain hole 8. Bottom of water tank 9. Extended drainage outlet 10 and drainage branch pipe 11.
