So what are the breeding methods of Australian lobster? The following small series will tell you.
1, shrimp pond excavation
The pond of Australian crayfish needs to be excavated in a place with sunny ventilation, quiet environment, sufficient water, no pollution source and convenient irrigation and drainage. Rectangular area is the best, and 3 mu to 5 mu is more suitable.
2. Supporting facilities
Farmers also need to remember to match the import and export facilities of Australian crayfish ponds, and don't forget to set up escape nets at the import and export.
The pond is surrounded by aquatic plants, covering an area of about one-fifth of the water surface, which is more suitable.
3. Raise shrimp seedlings.
The stocking time of shrimp fry is generally from March to May, and the water temperature is above 65438 08℃.
In the sunny morning or evening, the seeding time is 50px- 100px, and the density is 6000-8000/ mu.
Shrimp seedlings stocked in the same pond should be neat and consistent in specifications.
Step 4 feed the bait
Chopped small miscellaneous fish and minced meat can be added 3 days after shrimp fry are added; Small miscellaneous fish, waste meat and artificial feed can be put in the future 1 month; When the shrimp seedlings grow to 6-7 cm, they are replaced with crushed snails, mussels and other plant feeds.
The amount is about the shrimp seedlings leaving no residual bait.
5, breeding matters needing attention
Australian lobster has a good metabolism and a fast growth rate, so the water quality in the shrimp pond must be kept clean. It is best to supplement/kloc-0.5 to 20 cm of water every week to make the water in the shrimp pond have enough dissolved oxygen, and the transparency of the water in the shrimp pond should be controlled at about 35 cm.
There are many natural enemies of Australian lobster, such as mice, frogs, waterfowl, etc., which will cause harm to it.
Breeders must pay attention to mice, kill them in time and remove frogs from the pool.
Preventive measures can be taken, such as enclosing the shrimp pond for 30-40 cm to prevent frogs and water snakes from invading.
6. Arrest and listing
Generally, after the National Day of that year, net cages are used for batch fishing, or dry ponds or purse seines are used for one-time fishing at night.
Generally speaking, if you want to raise Australian lobster well, you must first master the above five breeding points, and each stage is more important. If you do well, you usually don't have a high mortality rate and a good income. Have you learned?
