My friend, although I am not a pilot, I almost flew into the blue sky at the beginning. I solemnly advise you not to expect any "customs clearance skills"! Flying is no laughing matter. We must be practical and realistic in terms of physical examination. If we can't, we can't! Even if you muddle through with some measures, you will eventually reap the consequences. The risk of flying is very high. If you lose your life due to an accident in the sky due to your physical condition, do you think it is cost-effective?
朕知道你鬼点子多、言辞也犀利，你就不用装老实了。

10-15% of aquatic plants and hidden objects are planted shallowly at the edge of the pond to create an environment for lobsters to inhabit and shell and reduce mutual killing. The influence of water quality on lobster yield cannot be ignored. During the breeding process, the PH value of the pool water is kept between 7.5 and 8.5, and the transparency is 30-40cm. Fresh water should be added frequently, quicklime solution should be splashed regularly, water quality should be adjusted, and diseases and shelling failure should be prevented. 2. Feed feed reasonably. Lobsters will kill each other when hungry and under-fed, so the feeding amount must be sufficient. Lobster feed is animal and plant feed. Plant feeds are wheat, aquatic plants, rapeseed cakes, etc. Animal feeds are miscellaneous fish, miscellaneous meat, livestock viscera, etc. At ordinary times, the feeding time, feeding amount and feeding method are determined according to the habit of lobsters falling in the day and coming out at night and the density of lobsters in the pond. 3. Scientific fishing. Young shrimps can grow to commercial specifications in 60-90 days under the condition of suitable temperature and sufficient feed.
