Description

A kind of artificial breeding device for crab species

technical field

The utility model belongs to the technical field of artificial breeding of crabs, in particular to a device for artificial breeding of crabs.

Background technique

In my country, economic sea and freshwater crabs occupy an important share in the aquatic product market and are high-end consumer goods. The freshwater crabs are mainly Chinese mitten crabs, while the seawater crabs mainly include blue crabs, three wart swimming crabs, rust-spotted squid, Japanese squid, far sea swimming crabs and red star swimming crabs. These crabs have the characteristics of fast growth, rich nutrition and delicious meat, and are very popular among people. In recent years, the output of artificial crab farming in my country has continued to increase, maintaining a good development momentum, and has great development space and breeding potential.

The healthy development of the breeding industry is inseparable from the support of high-quality seedlings. In the traditional artificial breeding process of crabs, the breeding crab ponds are mostly large ponds of dozens of square meters, and dozens of breeding crabs are placed in each large pond. Because crabs have the habit of killing each other, in the breeding process of breeding crabs, the breeding crabs often attack each other and cause their large claws to be cut off or injured, and the breeding crabs die due to wound infection. In addition, there will be residual bait and feces on the sand in the breeding crab pond, which is difficult to wash. If it is not cleaned for a long time, it will easily lead to the deterioration of the water quality, which will cause a large number of dead crabs and cause heavy economic losses. Therefore, how to raise the seed crab well, improve the survival rate of the seed crab, and improve the yield and quality of the crab seedlings are the problems that need to be solved urgently at present.

The utility model is provided with a special bait area, which can put bait. At present, most crab breeding devices do not have a special feeding area, so it is more troublesome to feed crabs and clean up. Moreover, after eating crabs, food residues will be left, which is difficult to clean. If they are not cleaned, food residues will remain in The sand can easily lead to the deterioration of the water quality and affect the crabs to hold eggs. The bait area of the utility model can be used for special feeding of crabs, the bait area has no sand, is easy to clean, and can maintain water quality.

The breeding of seed crabs requires a sandy bottom, so a very thick layer of sand (15-20cm) is required; during the breeding process, the bait and feces of the seed crabs are easily left on the sand, and it is difficult to clean up in the sand, so this The utility model adopts the recoil water inlet method, which can use the water flow to wash the residual bait and feces on the sand, and then discharge it through the drain outlet, so that the sand can be cleaned every time the water is changed, which is not only convenient to operate, but also has a good effect. Conducive to maintaining good water quality and improving the survival rate of species crabs.

Further, a box cover (14) is also included, and the box cover (14) is connected with the plastic hard board (4) through a hinge (15).

Further, the device body (1) is a plastic square box.

Further, both the water inlet pipe (2) and the drain pipe (12) are provided with valves (3).

Further, the height of the sand (5) is 15-20cm.

Further, the pier (8) is a solid plastic pier, and its height is 10-15 cm.

Further, the aperture of the strong nylon separator (6) is smaller than the diameter of the sand (5).

Further, the aperture of the perforated plastic separator (7) is larger than the aperture of the strong nylon separator (6).

Further, the solid plastic step (13) and the hard plastic board (4) are bonded by an adhesive.

Further, it can be used in the fattening and brooding stages of crab species. One species crab can be placed in each unit.

Compared with the prior art, the utility model includes a water inlet area (I), a sandy area (II), a bait area (III) and an oxygenation area (IV), and the structural design between them is reasonable, which can effectively save Use water and save aquaculture land, and also facilitate the flushing of the cultivation pond. The utility model is provided with a special bait area, and adopts the recoil water inlet method, which can use the water flow to wash the residual bait and feces on the sand, and then discharge them through the drainage port, so that the water can be cleaned every time the water is changed. Sand cleaning is not only easy to operate, but also conducive to maintaining good water quality and improving the survival rate of species crabs. The utility model also adopts the breeding method of "one crab, one box" to prevent the damage of the seed crabs caused by fighting and attack, thereby improving the survival rate of the seed crabs, reducing the risk and cost of raising seedlings, and can be used in the fattening and brooding stages of the crab seedlings. use.
