Problems solved by technology

Artificial shrimp nests have almost no effect on water quality, while aquatic plants can purify and stabilize water quality. Without aquatic plants, pond water quality will be difficult to control. Especially in summer and autumn, water quality is easy to be over-fertilized, causing harmful algae such as blue-green algae to break out, affecting green water quality. shrimp growth

Embodiment 1

[0021] A farmer arranges six 5-acre ponds to breed freshwater shrimp from the same source, divides the ponds into two groups, each group has 3 ponds, the stocking time is at the end of July, and the stocking density is 80,000 fish / mu. Adopt the same breeding management method. One group, one month before stocking, advanced water 15-20cm, adopted the planting method of cuttings, and planted Hydrilla verticillium according to the density of row spacing 5-6m and plant spacing 1-2m; after the aquatic plants survived, add water to 80-100cm; then The shrimp nests made of tea tree branches are arranged between the aquatic plants in each row. The row spacing between the shrimp nests is 5-6m, and the spacing is 3-4m, forming a row of grass and a row of shrimp nests. The other group, one month before stocking, advanced water 15-20cm, adopted the cutting planting method, and planted Hydrilla verticillium according to the density of row spacing 5-6m and plant spacing 1-2m. After the aqua...

Embodiment 2

[0023] In a farm, 6 ponds of 5 mu were arranged to breed freshwater shrimp from the same source, and the ponds were divided into two groups, with 3 ponds in each group. The stocking time was at the end of July, and the stocking density was 80,000 fish / mu. Adopt the same breeding management method. One group, one month before stocking, advanced water 15-20cm, adopted the planting method of cuttings, and planted Hydrilla verticillium according to the density of row spacing 5-6m and plant spacing 1-2m; after the aquatic plants survived, add water to 80-100cm; then The shrimp nests made of tea tree branches are arranged between the aquatic plants in each row. The row spacing between the shrimp nests is 5-6m, and the spacing is 3-4m, forming a row of grass and a row of shrimp nests. The other group added water to 80-100cm one month before stocking, and set up artificial shrimp nests with a row spacing of 5-6m and a spacing of 3-4m. The artificial shrimp nests were bundled with pean...

Abstract

The invention discloses a freshwater shrimp culturing method by comprehensively utilizing float grass and an artificial shrimp nest. The culturing method comprises the steps of planting float grass, setting the artificial shrimp nest, culturing and managing and the like. By popularizing and applying the method, on the one hand, the effects of purifying the float grass and stabilizing water quality can be played to easily manage the water quality in the freshwater shrimp culturing process, on the other hand, a place for inhabitation and concealment is furthest provided to freshwater shrimp, the culture survival rate, specification and yield of freshwater shrimp are improved, and the freshwater shrimp culture benefit is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and more precisely relates to a method for cultivating freshwater shrimp by comprehensively utilizing aquatic plants and artificial shrimp nests. Background technique [0002] Freshwater shrimp, scientific name Macrobrachium japonica, has tender meat, delicious taste, short breeding cycle, fast growth and high economic value. It is an important freshwater cultured shrimp in my country. [0003] There are many culture modes of freshwater shrimp, which can be main culture, mixed culture, rotation culture, etc. Currently, the main culture ponds for freshwater shrimp mainly use two methods to provide habitat and shelter for the growth and shelling of freshwater shrimp. One is to plant aquatic plants, and the other One is to use artificial shrimp nests. However, using both methods alone has its disadvantages: [0004] (1) Plant only aquatic plants: If the coverage area of ​​aquatic plants is too...
