Problems solved by technology

[0004] Procambarus clarkii fails to burrow in an indoor soilless culture system
If bamboo tubes or plastic tubes are used as artificial caves like outdoor artificial breeding, on the one hand, the bamboo tubes are prone to rolling and may frighten the shrimp;
In addition, placing multiple bamboo or plastic tubes will hinder the cleaning of dirt and residual bait in the water body, and is not conducive to daily observation

Embodiment 1

[0039] as attached Figures 1 to 4 As shown, a kind of artificial cave of Crayfish, including four PVC rigid tubular nests 4 and non-toxic black plastic flat nets of different specifications are cut to make the bottom surface 2, ceiling 1 and inner nest 3 of the artificial cave respectively. The overall length of the cave is 52cm, the width is 25cm, and the maximum height is 11.5cm. Each PVC rigid tubular nest 4 is 15cm long and 5cm in diameter. The hole diameter of the black plastic flat net on the bottom surface 2 is 1.8cm, and the cut size is 52cm × 25cm; the hole diameter of the black plastic flat net on the ceiling 1 is 1.2cm, and the cut size is 52cm × 33cm; the black plastic net of the inner nest 3 The aperture of the flat net is 0.3cm, and a piece of 52cm×33cm plastic flat net can be cut into four sections, each section is 13cm wide and 33cm long. After cutting, press Attach figure 2 , 3 , 4 to assemble and fix.

Embodiment 2

[0041] as attached Figure 5 As shown, the main structure of an artificial cave of Crayfish is the same as that of Example 1, the difference is that a second layer of structure is added on the basis of Example 1. The second layer structure includes a second layer roof 5 and a plurality of second layer inner cells 6 . The length of the second layer of roof 5 is the same as that of the first layer of roof 1 , but the width is slightly smaller than that of the first layer of roof 1 . Both ends of the second-layer roof 5 are fixed to the first-layer roof, and the middle is fixed to the middle of the first-layer roof 1 through the inner nest 6 of the second layer. The inner nest 6 of the second layer is different in structure from the inner nest 3 of the first layer. The inner nest 6 of the second layer is formed by bending a rectangular plastic flat net into a circular tube shape, and then fixing one end of the circular tube shape on the ceiling 1 of the first layer, and the othe...

Abstract

The invention relates to a procambarus clarkii artificial cave. The procambarus clarkii artificial cave comprises a ceiling, a bottom face, an interior nest and exterior hard tubular nests, wherein the ceiling, the bottom face and the interior nest are made of rectangular plastic plain nets of different specifications respectively to form the top, bottom and interior nest of the artificial cave; the ceiling is formed by bending a rectangular plastic plain net to be arched and enabling the rectangular plastic plain net to be fixedly aligned to the edge of the plastic plain net on the bottom to form a hollow tubular artificial cave with a semicircular cross section; the interior nest is formed in the artificial cave, and is formed by bending one end of a rectangular plastic plain net to be circular-tube-shaped and bending the other end of the rectangular plastic plain net to be S-shaped, then fixing the circular-tube-shaped end to the bottom face, and fixing the S-shaped end to the ceiling, thereby fixing the interior nest in the artificial cave; the four hard tubular nests are formed in the four exterior corners of the artificial cave and play the role of sinkers. The procambarus clarkii artificial cave has the advantages that manufacturing is simple, real-time monitoring and daily feeding management are facilitated, and the practicability is strong.

Description

technical field [0001] The invention relates to an artificial cave of Crayfish, belonging to the technical field of aquatic animal breeding. Background technique [0002] Proambaus clarkii, commonly known as "crayfish", belongs to the phylum Arthropoda, Crustacea, Decapoda, Procrayfish genus. Crayfish originating in North America was introduced near Nanjing, my country in the 1930s. Because of its delicious meat, various amino acids, high protein and low fat, and high nutritional value, it has been loved by many consumers. The demand in domestic and foreign markets has increased year by year, which has effectively promoted the development of the crayfish aquaculture industry. [0003] Crayfish usually inhabits freshwater waters such as lakes, ponds, rivers and ditches. Crayfish have the habit of digging burrows. Generally, when the weather is hot and cold, which is not conducive to their survival or reproduction, they will burrow in the water to avoid the unfavorable enviro...
