Problems solved by technology

[0003] In recent years, the Australian freshwater lobster farming industry has developed rapidly. However, the high-density farming model makes the ecosystem structure of the farming environment single and weak in resistance, which can easily lead to deterioration of water quality and frequent occurrence of shrimp diseases, which eventually lead to a large number of shrimp deaths and low survival rates.
In order to improve the survival rate, people use a lot of chemicals and antibiotics. Although the survival rate of shrimp has been improved to a certain extent, the negative effects of these drugs are also very obvious, not only changing the normal composition of shrimp intestinal flora, It leads to the imbalance of the micro-ecological environment in the intestinal tract, and also makes the drug remain in the organism, which hinders the healthy development of the pollution-free aquaculture industry

Embodiment 1

[0038] A kind of culture method of Australian freshwater lobster, comprises the following steps:

[0039](1) Pond selection: Choose a rectangular shape, built in a sunny place with ventilation, convenient irrigation and drainage, no water pollution, a flat and sandy bottom, a water depth of 1.3m, and a watertight pond as a breeding pond; the inlet and outlet of the pond should be installed with 80 mesh filter tulle, plant aquatic plants in the pond, and put in the shelter made of PVC pipes at the bottom of the pond; the shelter is an inline accumulation formed by connecting several PVC pipes; 30 of the shelters are set per mu; The height is 15cm, and the width is 45cm; the diameter of the PVC pipe is 15cm, and the length is 60cm;

[0040] (2) Pond disinfection: Disinfect the pond with fresh quicklime to remove miscellaneous fish in the pond;

[0041] (4) Breeding water treatment: after the pond enters the water, disinfect the water body with chlorine dioxide, and then apply f...

Abstract

The invention discloses a cherax quadricarinatus breeding method. The method comprises the following steps of pond selection, pond disinfection, breeding water treatment, compound bacteria culture, shrimp fry stocking, feed feeding and pond management. According to the breeding method, by reasonably arranging a shelter, breeding compound bacteria, adding EM bacteria and traditional Chinese medicine powder into feed and the like, breeding is conducted under the condition of not using hormones or antibiotics, the method has the advantages of being ecological, environmentally friendly, less in investment, low in cost and convenient to manage, and the cherax quadricarinatus obtained through breeding is high in survival rate, high in growth speed, healthy and strong in physique, high in diseaseresistance and high in stress resistance.

Description

technical field [0001] The invention belongs to the technical field of lobster cultivation, and in particular relates to a method for cultivating Australian freshwater lobsters. Background technique [0002] Australian freshwater lobster (Cherax quadricarinatus), whose scientific name is four-ridged light-shelled crayfish, also known as red-clawed crayfish, is a large freshwater crayfish belonging to the decapod Crayfish family. It is called Australian freshwater lobster because it is large in size and looks a bit like a lobster in the sea, and because it is native to Australia and only lives in fresh water. [0003] In recent years, the Australian freshwater lobster farming industry has developed rapidly. However, the high-density farming model makes the ecosystem structure of the farming environment single and weak in resistance. In order to improve the survival rate, people use a lot of chemicals and antibiotics. Although the survival rate of shrimp has been improved to ...
