Embodiment 1

[0060] There are 1 or two breeding ponds of 2.5 mu, and we are planning to build high-level ponds to raise freshwater shrimps. The single-culture farming model, the breeding cycle is from June to October, and the shrimp seedlings bred at the beginning of May are cultivated into large-scale shrimp species for stocking. The specific green shrimp farming methods yes:

[0061] 1. Shrimp nest setting. At the beginning of May, the breeding pond 1 was cleaned, and the shrimp nest structure 3 was set after disinfection. The multiple shrimp nest structures 3 were arranged in a straight line at a distance of 0.5 meters, and arranged in multiple rows, so that the total coverage area of ​​the shrimp nest structure 3 at the bottom of the breeding pond 1 accounted for 10% of the total area of ​​the breeding pond. About 6% of the pond 1, a single shrimp nest structure 3 covers an area of ​​about 0.45 square meters, and a total of 150 shrimp nest structures 3 are arranged in each culture pond...

Embodiment 2

[0072] There are 1 and 3 breeding ponds of 2.0 mu, and it is planned to build a high-level pond to cultivate green shrimp, fish and shrimp mixed culture. The breeding cycle is from June to October. The shrimp seedlings bred in early May are cultivated into large-scale shrimp species for stocking. The specific green shrimp The breeding method is:

[0073] 1. Shrimp nest setting. At the beginning of May, clean up the breeding pond 1, set the shrimp nest structure 3 after disinfection, surround a circle with a diameter of 10 meters with a plurality of shrimp nest structures 3, set two rows, and arrange 4 equidistantly in each row, so that the shrimp nest structures 3 are surrounded The area accounts for about 50% of the total area of ​​the culture pond 1.

[0074] Second, the planting of aquatic plants 2. After the shrimp nest structure 3 is set up, inject 20 cm of water, and plant euthermic aquatic plants after 1 week: Elodea, Hydrilla verticillium, mixed planting, and plant a...

Abstract

The invention relates to the technical field of aquaculture, and particularly discloses a shrimp nest structure, a freshwater shrimp culture method and application. The shrimp nest structure comprisesa mounting base arranged in a culture pond and a floating part used for floating on the water surface, the shrimp nest structure further comprises a plurality of nest platforms, and every two adjacent nest platforms are connected through a telescopic assembly. According to the shrimp nest structure, the floating part moves up and down along with the change of the water level, then the telescopicassemblies are driven to drive the multiple nest platforms to move up and down in the axis direction of the floating part, the distance between every two adjacent nest platforms is adjusted, and thenthe size of activity spaces for growth of shrimps cultivated on the shrimp nest structure is changed; and the problem that the freshwater shrimp yield per unit area is not high due to the fact that the freshwater shrimp growth activity spaces of existing freshwater shrimp culture equipment are small is solved, and the shrimp nest structure has wide market prospects.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a structure of a shrimp nest, a method for cultivating freshwater shrimp, and an application thereof. Background technique [0002] Green shrimp is a high-quality aquatic product rich in nutrition. It is delicious, easy to cook, and convenient to eat. It is suitable for all ages. At present, in the cultivation method of freshwater shrimp, it is generally directly put into ponds for cultivation. This rough cultivation method cannot guarantee the efficiency of artificial cultivation of freshwater shrimp, and the uniformity of the specification of freshwater shrimp cannot be guaranteed. There are also some culture methods that culture freshwater shrimp in net cages, but the equipment and facilities are relatively rough and laggy, and there is not enough space for green shrimp to grow and move. [0003] Therefore, the existing freshwater shrimp farming technology scheme has the ...
