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 specifically discloses a shrimp nest structure, a freshwater shrimp farming method, and an application. The shrimp nest structure includes an installation base arranged in a culture pond and a floating piece for floating on the water surface. The shrimp nest structure also includes a plurality of nest platforms, and two adjacent nest platforms are connected by telescopic components. In the present invention, the floating parts move up and down with the change of the water level, and then drive the telescopic assembly to drive a plurality of nest platforms to move up and down along the axial direction of the floating parts, so as to adjust the distance between two adjacent nest platforms, and then Changing the size of the activity space for the growth of the shrimp cultured on the structure of the shrimp nest solves the problem that the growth activity space of the existing freshwater shrimp farming equipment is small, resulting in a low yield of freshwater shrimp per unit area, and has broad potential market expectation.

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 ...
