Example Embodiment

[0020] Example 1:

[0021] A farmer arranges 6 5-mu ponds to breed green shrimp from the same source, and divides the ponds into two groups of 3 ponds. The stocking time is at the end of July, and the stocking density is 80,000 / mu. Adopt the same breeding management method. One group, one month before stocking, advanced water 15~20cm, adopted cutting planting method, and planted black algae at a density of 5~6m row spacing and 1~2m plant spacing; after the aquatic plants survived, add water to 80~100cm; then The shrimp nests tied with tea branches are set 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 layout of a row of grass and a row of shrimp nests. In the other group, one month before stocking, the advanced water was 15-20 cm, and the cutting method was adopted. After the aquatic plants survive, add water to 80~100cm without setting up artificial shrimp nests. By the end of the year, the harve...

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...
