Problems solved by technology

With the continuous improvement of people's living standards, people's requirements for quality of life are getting higher and higher, and people's requirements for diet quality are also very high. People's demand for crayfish with rich nutritional value is also growing rapidly, but the crayfish currently on the market The output cannot meet people's urgent needs. Due to the current water quality being polluted to varying degrees, the living environment of crayfish is deteriorating, making crayfish very susceptible to diseases. At the same time, the living environment of crayfish has limitations. The current freshwater crayfish There are certain disadvantages in artificial breeding, which cannot effectively ensure the fullness of the crayfish meat, which needs to be improved urgently

Embodiment 1

[0018] (1) Selection and construction of ponds: choose a pond with sufficient water source, clear water quality, no pollution, convenient drainage and irrigation, strong water retention capacity, fertile soil, and an area of ​​3-5 mu. The water depth is 1.5m, the slope ratio is 1:2, and the soil quality of the pond is Loam soil, drain the water in the pond, expose to the sun for 3-5 days, then put it into river water, and apply decomposed organic fertilizer at 400kg / mu, plant aquatic plants after 3-4 days of fertilization, and the covered area of ​​aquatic plants accounts for 50% of the area of ​​each pond. The water temperature is controlled at 24°C, the dissolved oxygen is at 5mg / L, and the transparency should be around 25cm.

[0019] Build a sunshade net with 95% shading degree along the 30-35% area above the pond in July-August.

[0020] (2) Seed stocking: in mid-March, the stocking specification is 2000 / kg healthy, disease-free and uninjured shrimp seed 20kg / mu; when the ...

Abstract

The invention discloses an ecologic breeding method of crayfish. The ecologic breeding method of crayfish comprises the steps of performing pond selection and construction, putting crayfish fries forbreeding, feeding bait, adjusting and controlling water quality, and performing disease control. According to the growth habit of the crayfish, the growth characteristics of the crayfish are mastered,so that the health of the crayfish is effectively guaranteed in the growth process of crayfish fries; aquatic product plants are planted in the pond to establish benign ecological environment and tobe provided for playing and eating of the crayfish, and besides, the water quality is timely and effectively purified and treated, so that the probability that the crayfish are infected with diseasescan be effectively reduced, the stress resistance is increased, and the autoimmunity is promoted; and the cultured crayfish are delicious in meat quality, the yield is high, and the breeding gain is increased.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a crayfish ecological breeding method. Background technique [0002] In recent years, the crayfish market is freshwater economical shrimp, which is widely welcomed by people because of its delicious meat. Because of its omnivorous nature, fast growth rate and strong adaptability, it forms an absolute competitive advantage in the local ecological environment. Its food range includes aquatic plants, algae, aquatic insects, animal carcasses, etc. It also kills each other when food is scarce. Crayfish has become an important economically farmed species in China in recent years. With the continuous improvement of people's living standards, people's requirements for quality of life are getting higher and higher, and people's requirements for diet quality are also very high. People's demand for crayfish with rich nutritional value is also growing rapidly, but the crayfish currently on the m...
