Problems solved by technology

Especially the ponds used to grow shrimp directly, some of them have a large area, and the whole pond consumes more fertilizer and water, which causes waste and is also a great waste of water resources
Secondly, egg-bearing shrimps are raised in free-range ponds, which is not conducive to recapture due to the large water surface.
Finally, if the pond is used to directly raise adult shrimp, it is necessary to plant grass before stocking the brood shrimp. Planting grass too early will cause the grass to grow too much. In order to prevent the grass from being too dense, it is necessary to cut off too much grass, which is a waste of manpower.

Embodiment 1

[0037] A method for cultivating shrimp seedlings utilizing the ring ditch structure 3 at the bottom of the pool. The cultivating process is carried out in June, wherein the egg-bearing shrimps are stocked from June 1 to June 15, and the specific cultivation steps are as follows;

[0038] a. Pond selection: Select a suitable pond 1 and drain the water in the pond 1 to keep it in a dry state. The selected pond 1 has an area of ​​30 mu, the inlet and outlet are separated, the depth of the pond 1 is 1.3 m, and the slope ratio of the pond ridge is 1:3 , Pond 1 is equipped with microporous aeration equipment;

[0039] b. Ring ditch excavation: Excavate the bottom ring ditch structure 3 at the bottom of the pond 1, the opening width of the zigzag ditch 4 and the longitudinal ditch 5 is 5m, the depth is 60cm, and the slope of the two side walls is 30°;

[0040] c. Water injection in the ring ditch; on June 1st, inject new water into the ring ditch structure 3 at the bottom of the pool...

Abstract

The invention discloses a pool bottom ring ditch structure for shrimp seedling cultivation and a method for cultivating shrimp seedlings. The pool bottom ring ditch structure includes a return-shaped ditch arranged at the bottom of the pond, and the return-shaped ditch is dug around the bottom of the pond. The zigzag ditch section is an isosceles trapezoid, and the zigzag ditch opening width is greater than the bottom width; the shrimp fry cultivation method comprises the following steps: a, pond selection; b, ring ditch excavation; c, ring ditch water injection; d, ring ditch ditch fertilization; e, egg-bearing shrimp stocking; f, feed feeding; g, catch or adult shrimp farming. The present invention excavates the ring ditch in the pond, and cultivates the shrimp seedlings in the ring ditch, which greatly reduces the volume of the water body in the early stage of seedling cultivation, thereby reducing the use of water resources and fishing medicines, and at the same time, less water body makes Water quality control is easier, and it also enables large-area ponds to be used for seedling production.

Description

technical field [0001] The invention relates to the technical field of freshwater shrimp breeding seedling breeding, in particular to a pond bottom ring ditch structure for shrimp seedling cultivation. Background technique [0002] The scientific name of freshwater shrimp is Japanese river prawn, commonly known as river prawn and lake prawn. Freshwater shrimp is tender in texture, delicious in taste and rich in nutrition. It is a famous and precious aquatic product loved by the masses, and it is also an important freshwater cultured shrimp in my country at present. With the rapid development of the freshwater shrimp farming industry, the supply of fine freshwater shrimp fry is in short supply. Farmers are also increasingly aware of the importance of high-quality seedlings for aquaculture production. Therefore, it is necessary to adopt scientific and efficient seedling technology to carry out the seed breeding of fine freshwater shrimp. [0003] Traditional freshwater shri...
