Northeast crawfish (Cambaroides dauricus) belongs to the family of arthropods, class of Soft-shelled turtle, order of decapod, crawfish family, genus crawfish, is one of world freshwater crawfish, and is named as northeast crawfish, lobster, northeast crawfish, Macrobrachium, and crawfish.
The crawfish has fresh meat, rich nutrition and unique flavor. Compared with other aquatic products, the muscle content of crawfish in northeast is lower than that of loach, mullet, bream and river crab, indicating that the meat is tender and easy to digest; the average content of crude protein is higher than that of mullet, finless eel, turtle, macrobrachium nipponensis, river crab and bream. A crawfish grown in natural water has developed liver embedded in scalp and breast, is known as "yellow" and has special flavor, and has crude fat content of 24.71-29.36%.
Northeast crawfish has been widely used in intermontane stream in northeast and in wide waters of Heilongjiang, Songhua and Liaohe river basin. Before the eighties of the last century, the method can be captured in mountain stream in northeast regions and in riparian seams of rivers such as Heilongjiang, Songhua and Liaohe river basin. Since crawfish has severe requirements for environment, it is difficult to see the shadow of crawfish in rivers of plain area and in mountainous areas with dense population due to human intervention and wide use of pesticides and chemical fertilizers in the eighties of the last century. At present, according to different specifications, the market price of northeast crawfish is 700 yuan/kg, and the breeding prospect is very wide.
Great economic benefit exists in breeding northeast crawfish, and most of breeding households begin to breed the northeast crawfish, but most of the breeding failures are caused by the fact that the breeding pond environment cannot meet the growth requirement of the northeast crawfish, so that the northeast crawfish cannot grow normally and dies gradually.

Design description:
northeast crawfish belongs to cold water aquatic animals, has high requirements on water source and water quality, and prefers water with clear water quality, high dissolved oxygen and cold water temperature in natural water area; therefore, a slightly cold water-based pond with little running water is selected for cultivation, the pond water is fresh during cultivation, the transparency is always kept above 50 cm, the dissolved oxygen is always kept above 6 mg/L, and the water temperature is below 28 ℃. In high-temperature seasons, a sunshade net is built on the culture pond, so that the direct sunlight intensity is reduced, the water temperature of the culture pond is always lower than 28 ℃, and the effect is good.
The crawfish is usually like to live in gaps between stones at the bottom of river bed or pond, in shallow water grass on the bank or under tree roots, pebbles and broken tiles with the diameter of 5-15 cm and the thickness of 20 cm are laid on the slope around the pond and at the bottom of two thirds of the pond, and a small number of branches are laid on the periphery of the pond, so that a good hidden place for crawfish in northeast and north is provided, and the survival rate of crawfish breeding is greatly improved.
The water hardness required for normal growth of northeast crawfish is more than 27 degrees; and coral sand or calcium carbonate with a thickness of 3-5 cm is laid at the bottom of the culture pond, and the water flow rate of the pond is slowed by the staggered distribution of the water flow ports of the pond stem 5 and the pond stem 5, so that the water hardness of the pond is always above 27 degrees, and the safety shelling of the northeast crawfish is ensured, thereby breaking through the key technology for culturing the northeast crawfish and ensuring the success of culturing the northeast crawfish.
Example 4
Constructing a northeast crawfish breeding pond in the east of Jilin province according to the embodiment 1 for large-scale artificial breeding; putting into northeast crawfish with average weight of 5.1 g/tail, and culturing for 4 months with soybean, corn and chicken intestine as feed to obtain commercial crawfish with average weight of 26.6 g/tail. The method can obtain 90000 yuan per mu of aquaculture pond, and obtain about 45000 yuan per mu of aquaculture pond on average, so that the economic benefit is considerable.
From the production experiment result, the crawfish breeding pond is suitable for large-scale artificial breeding of crawfish in northeast.
The invention changes the traditional soil pond aquaculture mode, intervenes in the water temperature and water quality of the aquaculture water artificially under the conditions of simplicity, convenience and easy operation and extremely small increase of input, changes the soil pond which is not suitable for breeding the northeast crawfish into a pond which is suitable for breeding the northeast crawfish, and obtains excellent economic benefit.
