Problems solved by technology

At present, there is no special feed for Procambarus clarkii in the market. If cheap general-purpose feed (raw material) is used, the absorption and utilization rate of the feed will be lower, and a large amount of waste will be discharged into the water, which is not conducive to the growth of Procambarus clarkii. Scale, safety, environmental protection, industrialization and efficiency
[0005] Biofloc technology can solve the above problems, but the use of biofloc technology to cultivate aquatic animals is a complex and dynamic process that requires the simultaneous participation of aquatic animals, zooplankton and microorganisms in the water environment.
At present, bioflocculation technology has been applied to species such as tilapia and Penaeus vannamei, but it has not been applied to the farming activities of Procambarus clarkii. How to adapt and make full use of bioflocculation in Procambarus clarkii is still a research hotspot

Embodiment 1

[0067] Disinfect the culture pond with an appropriate concentration of potassium permanganate, then add filtered culture water, fully aerate for 24 hours, then take a small amount of water and add AQ-II water body micro-ecological regulator (green Austrian Biotechnology, the main ingredients are bacillus, nitrifying bacteria, trace elements and compound enzymes, etc., the effective live bacteria content is not less than 10 billion / g), and the temperature is adjusted at 26-27°C.

[0068] On the third day, add pulverized feed, wheat bran and glucose with a mass ratio of 4:5:6 to the water body (the feed was purchased from Zhejiang Xinxin Feed Co., Ltd., the wheat bran was purchased from Chongmingcheng Feed Co., Ltd., and the glucose was purchased from Sinopharm Chemical Reagent Co., Ltd.), the carbon-nitrogen ratio is around 15 at this time.

[0069]On the seventh day, it can be found that the color of the water body has changed from clear and transparent to light yellow, and fl...

Embodiment 2

[0072] Extract river water into the breeding pond, fully aerate, maintain the dissolved oxygen in the water body at 6.0mg / L, and the temperature at 24-25°C, add activated AQ-Ⅱ water body micro-ecological regulator (Green Olympic) to the water body in the morning on sunny days Biotechnology, the main ingredients are bacillus, nitrifying bacteria, trace elements and complex enzymes, etc., and the effective live bacteria content is not less than 10 billion / g). Add the pelleted feed (actually measured CP32%) and feed bran (CP12.5%) that are ground at night, and add water-soluble glucose in the morning of the next day to adjust the carbon-nitrogen ratio of the water body to more than 15.

[0073] On the 5th day, put into the flocculation culture pond and feed feeding pond the same amount, normal body color, strong and healthy body without injury, no disease, no deformity, good food intake, flexible Crawfish claw (8-9g ), the stocking density is 25 / m 2 . Afterwards, at 7:00 every ...

Abstract

The invention provides a method for cultivating procambarus clarkii using biological flocculation technology, and the method is divided into two stages: establishing a biological flocculation cultivation system and daily cultivation management. In this cultivation method, the fake water grass is used as the flocculation attachment to improve the feeding efficiency, and the fake water grass also provides a sheltering place to reduce the mutual disability; according to the living habit of the procambarus clarkii, the breeding density is reduced, and the total suspended particulate matter concentration is also reduced. The cultivation method can maintain the good water quality of the cultivation water, reduce the feed coefficient, enhance the digestive enzyme activity and antioxidant level ofthe cultured animals, increase the yield and survival rate, save the labor cost, improve the unit labor efficiency and greatly reduce the cultivation cost.

Description

technical field [0001] The invention relates to a novel breeding method for Procambarus clarkii (Procambarus clarkii) by applying biological flocculation technology, belongs to the technical field of aquaculture, and is a healthy, efficient, environment-friendly, green, economical and ecological breeding method and technology. Background technique [0002] As a new water treatment technology, biofloc technology (Biofloc technology, BFT) is considered to be an effective way to solve the environmental and feed cost problems faced by the development of aquaculture industry. This technology can retain and utilize waste in water bodies, It has the characteristics of reducing the feed coefficient, increasing the feeding rate of farmed animals, promoting the digestion and absorption of ingested nutrients, improving the survival rate of farmed animals and reducing the discharge of breeding sewage. It is an advanced aquaculture technology. It adds carbohydrates to the water body, adj...
