Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The present embodiment provides an apparatus suitable for hatching the embryo of the red crayfish in vitro, which has the structure as shown in fig. 1 and fig. 2, and comprises a supporting base 1, an incubator 2, a first filtering body 3, a second filtering body 4, a water inlet pipe 5 and a water inlet pump 6. One end of the incubator 2 is closed, the other end is opened, and the closed end is fixedly arranged in the support base 1; a first filter body 3 and a second filter body 4 are arranged in the incubator 2, and the first filter body 3, the second filter body 4 and the side wall of the incubator 2 enclose an incubation space for incubation of the embryos of the red crayfish; the water inlet pump 6 is used for conveying culture water for the incubator 2; in incubator 2 was located to inlet tube 5, its one end ran through first filter body 3 and was connected with intake pump 6 through connecting pipe 7, and the other end runs through the water inlet that second filter body 4 regarded as incubator 2, and the water inlet filters the downside of body 4 at the second like this, filters the impurity that body 4 can effectively filter in the water through the second during intaking, purifies aquaculture water quality.

The incubator 2 is made of transparent organic glass, so that the growth and development conditions of the embryos of the red swamp crayfish can be observed conveniently; a water outlet 21 is arranged near the opening end of the incubator 2, and the water outlet 21 is arranged outside the incubation space. The water outlet 21 is arranged outside the hatching space for hatching the embryo of the red crayfish enclosed by the first filter 3, the second filter 4 and the side wall of the incubator 2, and the water of the red crayfish embryo in the hatching space can be prevented from being discharged along with the water flow due to the blocking effect of the first filter 3.

The utility model discloses a device suitable for hatching in vitro of red chela shrimp embryo makes the breed water be in the circulation flow state through intake pump 6 constantly to carrying aquaculture water in incubator 2 in the course of the work, for the red chela shrimp embryo provides sufficient dissolved oxygen, can guarantee simultaneously that the red chela shrimp embryo is in the suspended state all the time during the cultivation, more does benefit to the growth and development of red chela shrimp embryo.

Preferably, the first filtering body 3 and/or the second filtering body 4 are movably arranged in the incubator 2, such that by moving the position of the first filtering body 3 or the second filtering body 4 in the incubator 2, the volume of the enclosed hatching space can be adjusted, and the volume of the hatching space can be appropriately adjusted according to the number of hatching embryos.

More preferably, the first filter body 3 and the second filter body 4 are filter sponges, and the thickness of the filter sponges is 4-6 cm. The filtering sponge can effectively play a role in separation and filtering, the material of the filtering sponge is suitable for being cut into a corresponding profiling structure according to the shape of the inner wall of the incubator 2, and the filtering sponge is simple and convenient to manufacture and low in cost.

Preferably, the incubator 2 is cylindrical, which facilitates viewing of the growth and development of the embryos of the crayfish within the incubator 2 from various angles. More preferably, the closed end of the incubator 2 is in the shape of a circular arc, as shown in fig. 3, which is more suitable for fitting with the support base 1.

Application example:

at first, get the shrimp (red orange) of embracing the egg, peel off the egg gently through the comb, put into it after 60s with 70% alcohol disinfection treatment the utility model discloses an in incubator 2, can scatter the free back of moving (12 d back) to the seedling and make statistics of Stage2 juvenile shrimp (the juvenile shrimp that just incubate becomes Stage2 juvenile shrimp after 1 molt) survival rate. During the cultivation period, dead eggs are periodically removed, 3000ppm formaldehyde is used for disinfecting the eggs, and the hatching water is periodically disinfected by ozone. The results are shown in the following table.

The present invention is not limited to the above-described specific embodiments, and various modifications and changes are possible.
