A kind of Procambarus clarkii implantation device and hatching method thereof

Abstract

The invention discloses a Procambarus clarkii implantation device and a hatching method thereof. There are several vertical ridges, and gaps are formed between adjacent vertical ridges. There are drainage holes at the bottom of each cell cavity; the water mixed with shrimp eggs is injected into the cavity and continuously filled with water. After the shrimp eggs on the bed are implanted, place the implantation plate on the blocking plate, and each drainage hole on the blocking plate is provided with a corresponding ejector structure, and the drainage holes on the implantation plate are covered by the ejector structure. For blocking, a column grid frame is erected on the bed plate, and the side wall of each cell on the column grid frame surrounds the cells, and material exchange cannot be performed between adjacent cells. The implantation device mentioned in the present invention can provide a good environment for the hatching of shrimp eggs and improve the overall hatching efficiency.

Description

technical field [0001] The invention relates to the technical field of Procambarus clarkii culture, in particular to a Procambarus clarkii implantation device and a hatching method thereof. Background technique [0002] Procambarus clarkii: red crayfish and freshwater crayfish. It is shaped like a shrimp and has a hard shell. The adult is about 5.6-11.9 cm long, dark red, the carapace part is nearly black, and there is a wedge-shaped stripe on the back of the abdomen. The juvenile body is uniform gray, sometimes with black ripples. Claw long and narrow. The middle part of the carapace is not separated by mesh-like spaces, and there are obvious grains on the carapace. The frontal sword has side spines or the end of the forehead sword has notches. It is a freshwater economical shrimp, which is widely welcomed by people because of its delicious meat. Because of its omnivorous nature, fast growth rate and strong adaptability, it forms an absolute competitive advantage in t...

Problems solved by technology

[0003] The artificial breeding of Procambarus clarkii has not simulated its original growth environment, and the overall breeding process is too concentrated, it is difficult to manage and judge whether it is in a normal development state, and it may also cause shrimp damage due to infection, etc. Massive death of seedlings or failure to hatch
