Problems solved by technology
But at present, due to the large gap between the environmental conditions of the pond and the lake, the quality and taste of the cultivated river crabs are slightly inferior to those of the lake crabs, which affects the cultivation efficiency of the pond river crabs
Therefore, the pond construction in the pond crab cultivation process is one of the key links to improve the quality of river crabs. However, there is no research report on improving the quality of river crabs through the innovative construction of ponds in China.

[0019] 1. The choice of growing ponds
[0020] The river crab cultivation pond can be a new pond just excavated, or an old pond used for other purposes such as fish farming before the election. The required area is moderate, 10-30 mu is suitable, if it is too large, it will be difficult to operate and manage; if it is too small, it will be difficult to guarantee the water quality; if the water source is sufficient, it can guarantee the water demand in the dry season; the water intake and drainage are convenient, so that the pond can change water. There is no industrial pollution around.
[0021] 2. Renovation of the bottom of the pool
[0022] The transformation at the bottom of the pool is the most important key point of the present invention, and the concrete steps are as follows:
[0023] First, according to the size of the pond, reasonably determine the area and location of A, B, and C areas (attached figure 1 );
[0024] Area A: River crab parade area. The area ...

The invention discloses a method for constructing a high-quality river crab cultivation pond. The steps include: (1) selection of a pond for cultivation; (2) pond bottom transformation: according to the biological characteristics, living habits, lake ecological characteristics and pond characteristics of river crabs According to the actual conditions, the bottom of the pond will be transformed into a river crab parade area, bait spraying area, and aquatic plant breeding area; (3) pond ridge transformation; (4) escape prevention facility transformation; (5) aeration facility transformation. The present invention makes better use of the biological characteristics and ecological habits of river crabs, effectively improves the water quality conditions of ponds, and guarantees the production of high-quality large-scale adult crabs, which not only plays a positive role in promoting the development of crab culture in ponds in my country, but also contributes to the reduction of The dependence of river crab farming on lakes in my country has brought huge benefits and impacts to the improvement and protection of lake ecological environments.
Description
technical field [0001] [The present invention relates to the field of aquaculture, in particular to a pond construction or transformation method in the cultivation of high-quality river crab ponds. Background technique [0002] River crab, scientific name Chinese mitten crab ( Eriocheir sinensis ), is an extremely important aquatic economic organism in my country. In 2012, the national river crab production exceeded 700,000 tons, and the output value exceeded 40 billion yuan. It is one of my country's important export-earning aquatic products and the most culturally rich aquaculture object. It is rich in cultural connotations and can be called my country's famous and excellent aquaculture A wonderful flower of the industry. Therefore, river crab farming is one of the most dynamic and promising pillar industries in aquaculture in my country. In many areas of the country, the river crab industry is regarded as a pillar industry for adjusting the agricultural industrial str...
