At present, the most extensive way of lobster culture is shrimp and rice culture, and in addition, intensive culture is carried out in ponds. Different farming methods have different yields. For example, in shrimp and rice farming, 30-40KG of tiger shrimp fry are usually put in 1 mu, and the size of shrimp fry is 1 money weight, and about 6000-8000 shrimp fry are put in 1 mu. In many cases, lobsters will be salvaged and sold in a month. At this time, the personal weight of lobsters is not enough to 50 grams. The relative density of lobster culture in intensive ponds will be larger.

1 mu, the total number of shrimp fry put in is around 12000, and the output of 1 mu pond is around 500-600 kg after two seasons of cultivation. Naturally, this is all under the condition of better breeding. If important pests and diseases occur and many people die, the output may be zero. Rice and shrimp farming: 200-300 kg in the season, not to mention the master level, the average is at this level. After planting rice, there is basically no shrimp that can be sold. Double cropping: 400-500 kg, which is also a passing level.

In terms of specific culture, the key profit of rice and shrimp culture in the first quarter is not in the product shrimp, but in selling early shrimp seedlings. At the peak time, the price is 35 Jin, and the seedling winner gets the world. After 2008, you will earn money if you can make money in ten days, and if you can't make money, it will be crooked this year. If intensive cultivation is used, the jack production per mu is reliable, and only a few farmers can achieve the jack production level. I often see some people on the Internet, and some people write that after three jacks are produced per mu.

Those people lack basic knowledge. What are they talking about? In other breeding methods, it is good that the yield per mu can reach 300~400 kg, and it is a great god to reach 500 kg. Therefore, except for intensive cultivation and greenhouse, anything that touts the jack per mu is all touted, so as to prevent being deceived. The output of crayfish culture is closely related to whether the amount of seedlings is moderate, scientific culture methods, reasonable culture environment and scientific management.
