Problems solved by technology

[0002] 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

[0020] A method for cultivating Australian freshwater lobsters, comprising the following steps:

[0021] (1) Selection of shrimp ponds: The shrimp ponds are rectangular, built in places where the ventilation is sunny, the environment is quiet, the drainage and irrigation are convenient, and the water quality is free from pollution. The water depth is 1.5 meters, and the bottom of the pond is sandy and flat. ; The inlet and outlet of the shrimp pond are equipped with filter silk nets, and aquatic plants are placed in the pond. The coverage of aquatic plants is 1 / 3 of the water surface of the shrimp pond; stones and tiles are placed at the bottom of the pond as shelters, or 30 old tires for lobster shelter;

[0022] (2) Disinfection of the pond: Disinfect the shrimp pond with quicklime at a rate of 100 kilograms per mu. If moss appears in the pond, spray 0.25 kilograms of copper sulfate per mu on the mossy place;

[0023] (3) Cultivate water: After the shrimp pond enters the wa...

Embodiment 2

[0032] A method for cultivating Australian freshwater lobsters, comprising the following steps:

[0033] (1) Selection of shrimp ponds: The shrimp ponds are rectangular, built in places where the ventilation is sunny, the environment is quiet, the drainage and irrigation are convenient, and the water quality is free from pollution. The water depth is 1.5 meters, and the bottom of the pond is sandy and flat. ; The inlet and outlet of the shrimp pond are equipped with filter silk nets, and aquatic plants are placed in the pond. The coverage of aquatic plants is 1 / 2 of the water surface of the shrimp pond; stones and tiles are placed at the bottom of the pond as shelters, or 50 old tires for lobster shelter;

[0034] (2) Disinfection of the pond: Disinfect the shrimp pond with quicklime at a rate of 100 kilograms per mu. If moss appears in the pond, spray 0.25 kilograms of copper sulfate per mu on the mossy place;

[0035] (3) Cultivate water: After the shrimp pond enters the wa...

Embodiment 3

[0044] A method for cultivating Australian freshwater lobsters, comprising the following steps:

[0045] (1) Selection of shrimp ponds: The shrimp ponds are rectangular, built in places where the ventilation is sunny, the environment is quiet, the drainage and irrigation are convenient, and the water quality is free from pollution. The water depth is 1.5 meters, and the bottom of the pond is sandy and flat. ; The inlet and outlet of the shrimp pond are equipped with filter silk nets, and aquatic plants are placed in the pond. The coverage of aquatic plants is 1 / 2 of the water surface of the shrimp pond; stones and tiles are placed at the bottom of the pond as shelters, or 40 old tires for lobster shelter;

[0046] (2) Disinfection of the pond: Disinfect the shrimp pond with quicklime at a rate of 100 kilograms per mu. If moss appears in the pond, spray 0.25 kilograms of copper sulfate per mu on the mossy place;

[0047] (3) Cultivate water: After the shrimp pond enters the wa...

Abstract

The invention discloses a Cherax quadricarinatus cultivation method, comprising the steps of crayfish pond selection, pond sterilization, water cultivation, fry adding, feed adding and crayfish pond management. By applying biological fertilizers in a water body to improve the quality of the water body, it is possible to fertilize the water quickly and also increase dissolved oxygen in the water body, providing a good water body environment for Cherax quadricarinatus; the feed for Cherax quadricarinatus is rich in nutrition and is good in palatability such that body weight of Cherax quadricarinatus increases quickly, and individual weight of adults of Cherax quadricarinatus is 1.5-2 times the body weight of common members of Cherax quadricarinatus; in addition, for traditional Chinese medicine additives in the feed, synergy of the traditional Chinese medicine components is given to full play by making use of the monarch, minister, assistant and guide compatibility theory in traditional Chinese medicine, antibacterial and anti-inflammatory, heat-clearing and toxin-removing and immunity-improving effects can be achieved, the adjustment for body balance and intestinal ecological environment of Cherax quadricarinatus can be significantly improved, survival rate of Cherax quadricarinatus is up to 91.5-93.6%, no medicine residue occurs, and health and safety are ensured.
