Problems solved by technology

Acidification of the water affects the aerobic metabolism of the gill filament cells of the Procambarus clarkii, thereby causing the respiratory disorder of the Procambarus clarkii, which in turn affects the enzyme activity and tissue structure of the gill filament, hepatopancreas and muscle of the crayfish, and finally leads to its growth. Decreased speed, increased death rate

Embodiment 1

[0016] A method for improving the acid stress resistance of Procambarus clarkii, comprising the following steps:

[0017] The 1st step, basic ration preparation: Procambarus clarkii body weight is 1~10g, and protein content is 35% in the basic ration, and fat content is 8%; Procambarus clarkii body weight is greater than 10g, and protein content in the basal ration is 30%, with a fat content of 6%;

[0018] Step 2, compound Chinese herbal medicine preparation: in parts by weight, every 100g of compound Chinese herbal medicine contains Thyme 25g, Bupleurum 10g, Scutellaria baicalensis 15g, Rehmannia glutinosa 20g, motherwort 15g and Huajuhong 15g; all Chinese herbal medicine raw materials are freeze-dried, ground and pulverized Pass through an 80-mesh sieve and store at 4°C.

[0019] Step 3, seed feeding: the body weight of Procambarus clarkii is 1-10g, the mass fraction of compound Chinese herbal medicine added in the basal diet is 0.4%-0.6%; the body weight of Procambarus cl...

Embodiment 2

[0032] A method for improving the acid stress resistance of Procambarus clarkii, comprising the following steps:

[0033] The 1st step, basic ration preparation: Procambarus clarkii body weight is 1~10g, and protein content is 35% in the basic ration, and fat content is 8%; Procambarus clarkii body weight is greater than 10g, and protein content in the basal ration is 30%, with a fat content of 6%;

[0034] Step 2, compound Chinese herbal medicine preparation: by weight, every 100g of compound Chinese herbal medicine contains Thyme 25g, Bupleurum 10g, Scutellaria baicalensis 15g, Rehmannia glutinosa 20g, Motherwort 15g and Citrus red 15g; said Chinese herbal medicine raw materials are freeze-dried and ground Pass through an 80-mesh sieve after crushing, and store at 4°C;

[0035] Step 3, seed feeding: Procambarus clarkii has a body weight of 1 to 10 g, and 0.5% compound Chinese herbal medicine is added to the basic diet; the weight of Procambarus clarkii is 10 to 25 g, and 0....

Abstract

The invention discloses a method for improving acid stress resistance of procambarus clarkia. The method includes the steps of preparing basic ration, preparing compound Chinese herbal medicines and feeding larvae. Compared with the prior art, the method has the advantages that by means of the method, the anti-stress ability of procambarus clarkia under acidic water quality stress is enhanced, and the growth and survival ability of procambarus clarkia in an acidic environment is improved; by means of the basic ration in the method, due to the proper proportions of protein, fat and Chinese herbal medicines, the immune enhancing ability of procambarus clarkia under an acidic stress condition is improved, and the death rate of procambarus clarkia is decreased; the basic ration and Chinese herbal medicines belong to environment-friendly feed, meet safety standards, are not left in shrimp bodies, cause few side effects on a water body environment, and meet environment-friendly aquatic product additives; the method is easy and convenient to operate and low in cost.

Description

technical field [0001] The invention belongs to the field of aquaculture, relates to aquaculture management and feed feeding technology, in particular to a method for improving resistance to acid stress of Procambarus clarkii. Background technique [0002] Water pH is one of the important environmental factors in aquaculture. In recent years, acid rain and industrial pollution have caused acidification of pond water, which has led to aggravated pH fluctuations in aquaculture water. Procambarus clarkii belongs to euthermic organisms, and can grow and develop normally in the water temperature range of 10-31 °C. It can also withstand high temperature and severe cold, and can survive at a water temperature of 40°C. At the same time, it can dig holes to survive the winter when the temperature is -14°C. Due to its good natural adaptability, Procambarus clarkii has become the most common freshwater economic shrimp in the country. [0003] Procambarus clarkii has strong adaptabili...
