Description of the Related Art Conventionally, the biggest drawback in aquaculture of crustaceans such as shrimp is the cannibalism during the growth process and the poor yield due to being eaten by external enemies. Especially, it is remarkable during the molting several times each time the crustacean grows, and it takes about 1 to 2 days until the shell becomes normal hardness after molting, and there is no kinetic power during the normal period. , Being eaten by the same kind and foreign enemies.

It consists of a large number of dividing rods attached to the floating plate member at intervals so that the crustaceans can be positioned, and the length of the dividing rods is set so that it can be placed at a distance above the bottom of the aquaculture area so that it can eat at least. It is a crustacean farming tool of composition. In addition,
It may be a dividing rod whose length can be changed.

底部に降りるのである。[Function] By floating the floating plate member in the aquaculture pond or aquaculture tank, a large number of dividing rods hang down, and there is at least an interval above the bottom of the aquaculture area where food can be eaten. Due to their habits, crustaceans enter between narrow dividing rods and descend to the bottom when feeding on food.

Predation can be prevented. Furthermore, the floating plate member can prevent the rise in water temperature due to direct sunlight in summer.

In the present example shown in FIG. 1, reference numeral 1 denotes a styrene foam quadrangular floating plate member, and a large number of partition bars 2 are inserted into and fixed to the floating plate member 1 at predetermined intervals so that the bottom surface side of the floating plate member 1 is fixed. Overhangs.

Further, the interval between the dividing rods 2 is to be opened according to the growth of the crustacean, and the interval for shrimp is 3 to 18 mm. Furthermore, the length of the dividing rod 2 varies depending on the aquaculture area, and it is sufficient to leave an interval of 5 cm from the bottom of the aquaculture area to the upper part, which is usually 5 cm. In this example, the length of the sorting rod 2 is set to 35c as the one used for the aquarium having a depth of 40 cm from the juvenile shrimp to the parent shrimp.
m and the interval is 15 mm.

のである。In this embodiment having such a structure, by floating the floating plate member 1 in the aquaculture tank, a large number of dividing rods 2 hang down, and there is at least a space above the bottom of the aquaculture tank for predation. Due to its habit, crustaceans such as shrimp enter between the narrow dividing rods 2 as shown in FIGS. 2 and 3 and descend to the bottom when feeding food. It should be noted that, depending on the growth of the shrimp, the separating rods 2 are replaced with those having a larger interval.

めストレスによる共食いも減少できるのである。According to this example, since the distance between the dividing rods 2 is narrow, it is possible to move in the vertical direction, but it is difficult to move in the horizontal direction, so that cannibalism is reduced and it is difficult to be eaten by a foreign enemy in the water. In addition, the floating plate member 1 can prevent predation from birds, and the floating plate member 1 can prevent a rise in water temperature due to direct sunlight in summer. Further, since the floating plate member 1 moves due to the water flow, cannibalism due to stress can be reduced.

For example, regardless of the shape or material of the floating plate member, a floating material or a structure capable of floating can be used. Further, the shape and material of the dividing rod are not limited, and may be made of plastic, bamboo shape as shown in FIG. 4 or branch and leaf shape as shown in FIG.

い。Further, the configuration of the dividing rod is also appropriate, and as shown in FIG. 6, the length of the dividing rod is adjusted by inserting the inner rod 22 into the outer cylinder 21 and allowing the inner rod 22 to expand and contract. May be. According to this, by adjusting the length of the dividing rod according to the depth, it is possible to arrange in an optimum state. The aquaculture area to be used is also arbitrary and may be aquaculture ponds or aquaculture tanks.

The predation of this is prevented. In addition, the floating plate member can prevent a rise in water temperature due to direct sunlight in summer, and the floating plate member can be moved by the water flow, so that a good aquaculture environment can be achieved. According to the second aspect of the present invention, the length of the dividing rod can be adjusted according to the depth so that the dividing rod can be arranged in an optimum state.
