Description

[Detailed explanation of the idea]

This invention relates to a fish transport device used for transporting fish in a live state. Conventionally, this type of fish transport device has been widely used to place fish in an aquarium filled with seawater and transport the fish in a swimming state while supplying oxygen to the seawater. However, with this conventional device, if too many fish are placed in the aquarium, swimming fish may collide with each other and cause injury to the fish, and even if there are not that many fish in the tank, transportation may be difficult. If the fish, confused by the shock of time, collide with the aquarium while running away, they may collide with each other and be injured.
There is a problem that the economic value of fish that is damaged in this way decreases as a product for sale.Furthermore, because the seawater cannot be replaced during transportation, fish urine accumulates, making the seawater in the tank dirty and having a negative impact on the fish. The points were also hot. This invention was made in order to solve the above-mentioned problems, and it is an object to provide a fish transportation device that can transport fish without damaging them, purifies seawater, and uses less seawater. With the goal. Examples of this invention will be described below based on the drawings. The fish transport device 1 of this invention is loaded onto a car, boat, etc. and transported to a destination, and in this embodiment, as shown in FIG. It is stored in B. The fish transport device 1 includes a storage tank 3 within an aquarium 2, with opening surfaces of both tanks 2 and 3 aligned. The storage tank 3 is smaller in height and width in one direction than the water tank 2, and its bottom surface 4 is spaced apart from the inner bottom surface of the water tank 2, and is attached to the inner surface of the water tank 2 without any gap in the lateral direction. There is. Therefore, a lower space 5 and a space 6 are formed between the water tank 2 and the storage tank 3. The water tank 2 and the storage tank 3 are molded from synthetic resin, and the bottom surface 4 of the storage tank 3 has a large number of small holes 7, and the water tank 2 and the storage tank 3 communicate with each other through the small holes 7. are doing. Furthermore, protrusions 8 are provided on the inner surfaces of one set of opposing inner surfaces of the storage tank 3 at equal intervals in the vertical direction, and a large number of small holes are formed across the upper surfaces of the plurality of sets of protrusions 8 having the same height position. A plurality of partition plates 10 (three in the illustrated example) are removably mounted. A water-permeable cushioning material 11 made of sponge or the like is placed on the top surface of each partition plate 10, and a large number of fish F are placed horizontally on the top surface of the water-permeable cushioning material 11 at appropriate intervals. Another sheet of water-permeable cushioning material 11 is placed on it. In other words, a large number of fish F are stored in the storage tank 3 in a state where they are sandwiched horizontally between the two water-permeable cushioning materials 11, 11. In the space 6 of the water tank 2, a vertical portion 13 of a doglegged tube 12 is arranged with its open end facing downward, and a seawater circulation pump 14 is disposed in the vertical portion 13. In addition, the horizontal portion 15 of the dogleg tube 12 extends horizontally above the opening surface of the water tank 2 along this opening surface, and has a large number of water sprinkling ports provided at the opening end of the bent tip. The water sprinkling section 16 has
It is arranged near the opening surface above the center inside the storage tank 2. One end of an oxygen supply pipe 17 is connected to the horizontal portion 15 of the dogleg tube 12, and the other end of the oxygen supply pipe 17 is connected to an oxygen cylinder 18 installed outside the outer box B. In this embodiment, a storage tank 3 is provided within the water tank 2, and the seawater in the formed space 6 is pumped up and circulated by the seawater circulation pump 14, but this invention is not limited to such a structure. There is no problem,
Any structure may be used as long as it can circulate the seawater in the storage tank 3 not only locally but also throughout the tank. Next, the effect of this invention will be explained. When putting fish into the storage tank 3, first supply seawater into the tank 2 from a water supply port (not shown), raise the water level to slightly above the bottom 4 of the storage tank 3, and then
A sheet of water-permeable cushioning material 11 is placed on the bottom surface 4. Next, when a large number of fish F are placed on the upper surface of this water-permeable buffer material 11, water supply is started again and the water level is raised to slightly above the water-permeable buffer material 11. At this time, since the water level on the water-permeable buffer material 11 is low, the fish F has difficulty breathing in a normal position, so it turns sideways on the water-permeable buffer material 11. When the fish F is turned sideways, another water-permeable cushioning material 11 is placed over it, and then a partition plate 10 is installed on the protrusion 8 above it. When the installation of the partition plate 10 is completed, water supply is started and the water level is raised to the partition plate 10. After this, in the same manner as above, the process of placing the fish F on the partition plate 10 in a sandwich-like state horizontally using two water-permeable cushioning materials 11, 11 is repeated, and the first
The storage work for fish F is completed in the state shown in the figure. still,
C indicates the water level when the storage work is completed, and this water level C is maintained above the partition plate 10 installed at the top stage. When the storage work of the fish F is completed as described above, the seawater circulation pump 14 is activated, and the dogleg tube 1
The seawater in the space 6 of the water tank 2 is pumped up through the water tank 2 through the water tank 2, and the pumped seawater is returned to the storage tank 3 from the water sprinkling part 16 to circulate the seawater. Here, the seawater pumped into the doglegged pipe 12 flows into the horizontal part 15 from the vertical part 13, where it takes in oxygen sent from the oxygen supply pipe 17, and then returns to the water sprinkling part 16. . The oxygen contained in this returned water is used by fish F for respiration. Seawater with a relatively low dissolved oxygen concentration that passes through the small hole 7 provided in the bottom 4 of the storage tank 3 and flows into the water tank 2 is pumped up by the seawater circulation pump 14 and supplied with oxygen again in the doglegged pipe 12. After being
Since water is returned into the storage tank 3 from the water sprinkling section 16, the dissolved oxygen concentration of the seawater in the storage tank 3 is always maintained within a range suitable for the survival of the fish F. In addition, when the seawater thus circulated passes through each of the water permeable buffer materials 11, the filth such as the urine of the fish F contained in the sea water passes through the inner walls of the many pores interposed inside the porous water permeable buffer material 11. The seawater is purified during circulation. The dirty water-permeable buffer material 11 can be easily washed with water. Note that seawater with a high dissolved oxygen concentration that is returned to supply oxygen to the fish F is returned into the storage tank 3 from the water sprinkling section 16 provided at the upper center of the storage tank 3. 3. In order to prevent insufficient oxygen supply to the fish F near the wall due to a decrease in the amount of seawater returned to the vicinity of the inner wall, the small hole 9 of the partition plate 10 is located in the center, as shown in FIG. It is formed so that the diameter becomes larger toward the outside, thereby promoting the diffusion of the seawater. In addition, as shown in FIG.
By using the water sprinkling section 21, which is constructed by arranging a plurality of O. High seawater can be evenly returned to each location in the storage tank 3. As is clear from the above explanation, the fish transport device 1 of this invention stores the fish F with the fish F sandwiched sideways in a sandwich-like manner between two water-permeable cushioning materials 11. , the fish F will not run wild and collide with each other, and the fish F will be stored in a state as if lying on a cushion, so that the fish F will not be injured. Furthermore, while the seawater is circulating, the filth in the seawater is adsorbed to the water-permeable buffer material 11 and removed, so the seawater is kept clean and does not have any adverse effects on the fish F. Furthermore, since the amount of seawater that was conventionally required in large quantities to prevent fish collisions can be reduced, transportation costs can be significantly reduced. Examples of transporting fish using the device of this invention are shown in the table below. In addition, with conventional equipment, approximately 1 ton of seawater was required to transport the same amount of fish as shown below. Therefore, with the device of this invention, only one-fourth the amount of seawater was needed. Furthermore, as shown in the table below, there are almost no dead fish or injured fish.
