a method for the single three-dimensional industrial aquaculture of Australia crayfish comprises the following steps:

l, preparing before nourishing. And building a Australia freshwater lobster monomer three-dimensional industrial aquaculture device in the aquaculture pond 10 about 10 days before stocking, and keeping the overall stability of the aquaculture device. Then, filling water, sterilizing the culture pond and the culture device, and soaking for 30 minutes by using 10-20g/m3 of formalin and 3-5mg/kg of potassium permanganate. 100 g/m of quicklime 3 or 5-10g/m of medicine 3 is decocted by dried pepper and ginger (each l kg of dried pepper and ginger is added with 5-10 kg of water and boiled for 30-45 minutes), and the mixture is splashed in the whole pool. Changing water after soaking for 1-2 days, and changing water after soaking for 1-2 days with clear water.

2. And (5) putting and breeding seedlings. The fingerlings are required to be regular as much as possible, the appendages are healthy, diseases and injuries are avoided, and the healthy vigor is strong. When seedlings are put, a small amount of culture water can be slowly added into the seedling conveying container to adjust the water temperature so as to slowly adapt to the Australia freshwater lobsters until the water temperature in the container is basically consistent with that of the culture water to avoid overlarge temperature difference. And opening the small doors of the cultivation box, putting the seedlings into the cultivation box one by one, and then closing the small doors. The fry breeding is usually carried out in the morning or evening, which is suitable.

3. And replacing with water. In the culture process, the water body is generally completely replaced once a day, and the time can be set at 07: 00-09: 00 or 17: 00-19: 00. after the dried water is put, the operations of seedling putting, bait throwing, catching, daily observation and management and the like are carried out, and the water body (the water body must pass through the top of the culture box) is filled after the operations are finished, so that the exposure time of the Australian freshwater lobster is reduced as much as possible. In the actual culture process, according to the conditions of water quality and the like, the water can be properly changed by adopting a mode of water feeding and water discharging at ordinary times, the water body is kept clean as much as possible, but the water level is always not lower than the top of the culture tank.

4. And (5) feeding the feed. Feeding once a day, and placing in a position of 07: 00-09: 00 or evening at 17: 00-19: 00. the compound feed can be used, and the fresh feed can also be used, for example, the crayfish is fed according to 10-15% of the weight of the crayfish and the adult crayfish is fed according to 5-10% of the weight of the crayfish when the fresh feed is fed, and the feeding amount of the compound feed is fed according to the corresponding feed specification. The feeding condition of the lobsters must be observed every day, the feeding amount is timely adjusted according to the feeding condition, the growth of the lobsters is influenced by too little feeding, the cost is increased by too much feeding, and the water quality in the cement pond is deteriorated. In addition, the feed feeding should be flexibly mastered according to the conditions of weather, water temperature, water quality and the like, and can be timely and reasonably adjusted.

5. And (5) water quality requirements. Overall, australian crayfish has a relatively low water quality requirement compared to other farmed organisms. The shrimp has strong adaptability, can endure severe weather environment, can normally live at the water temperature of 5-35 deg.C, and has strong vitality resistance. But the good water quality is regulated and controlled, the healthy and rapid growth of the Australia crayfish is one of key factors, and effective means must be adopted in the culture process to keep the good water quality. The main measures are as follows: adding new water, and adopting a mode of discharging water and feeding water in the culture process on the basis of complete replacement once a day. And secondly, aerating by micropores, and installing an aeration device 60 to carry out necessary aeration and oxygenation. ③ in general, the temperature is controlled to 15 to 25 ℃, the pH is controlled to 6.5 to 9.0, and the dissolved oxygen is preferably kept at 4mg/L or more.

6. And (5) daily management. In daily management, besides the regular observation of feeding, activities, growth and shelling of Australia crayfish, the change of water quality and the environment of the bottom of the pond is noted and recorded. When the dissolved oxygen in water is low, the water quality is deteriorated, or the weather is rainy and hot, or the weather is cloudy, the bait feeding is reduced or stopped. The lobsters grow fast, are vigorous in metabolism and high in oxygen consumption, and the water quality of the lobster pond needs to be kept fresh and fresh frequently and has enough dissolved oxygen. In the culture period, diseases generally do not occur, and mainly prevent and treat diseases.

7. And (5) harvesting and conveying. The Australia crayfish grows fast, and generally can be harvested and marketed in the same year when being stocked in the same year. Experiments show that the freshwater lobster can survive after leaving water for 48 hours. Therefore, the shrimp can be transported by a plastic foam box in a dry method, a small amount of aquatic weeds are placed on the plastic foam box, and about 200 tails of shrimps can be placed in the plastic foam box of 60X 40X 30 cm. During transportation, the patient needs to be ventilated and cannot be squeezed, the transportation time is too long, and the patient needs to be watered midway, so as to avoid death.
