2020-02-26 06:07:37
1. What conditions are needed?
A: Crayfish have a strong adaptability to the environment and can grow in various bodies of water such as lakes, ponds, rivers and rice fields. The water source should be sufficient and the water depth should be about 1 meter.
2. Can the crayfish be cultured in a goldfish tank?
A: Yes, but it is impossible to form aquaculture and it does not produce economic benefits.
3. How to raise crayfish income?
Answer: Generally, 30 pounds of shrimp are stocked per acre, and 200 to 300 pounds of crayfish can be produced. The net profit can reach around 1,000 yuan. After five or six years, even if no shrimp is put in, the yield per mu can reach 200 pounds.
4. When did you start raising the shrimp and where did the shrimp come from?
Answer: Generally, shrimps are stocked in September each year and harvested from May to June in the following year. It is advisable to buy shrimp of the nearest species and choose large crawfish with hard shells. This year's shrimp resources are tight, and farmers who are interested in breeding crayfish can purchase shrimp in advance and stock up again in September.
5. Will the popularization of crayfish now be harmful to ecology and flood control?
A: The destructive power of crayfish is not strong. First, it needs to grow in a specific environment; in addition, in aquatic products, crayfish breeding capacity is not the strongest, a female shrimp can breed two hundred shrimp. At present, the export of crayfish and domestic demand are still in short supply. Crayfish can be easily caught, even if left unattended, and will not pose a great threat. In addition, although the crayfish likes to make a hole, the test found that the depth of the hole is only 20 to 30 centimeters, and the highest is only one meter deep. It goes along the diagonal line toward the groundwater and will not pose a threat to flood control.
