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. The seedlings will be released in March and will be caught in rotation around June, selling large ones and keeping small ones.

Some "researchers according to * * * research" always confuse their career with their amateur and make some marginal suggestions. There are also some coaches or training methods that are too professional. From the perspective of improving the national competitive level and striving for gold medals, they are determined to improve the limits of human body. For amateurs, there are also some undesirable points and they should have their own judgment. Also don't follow professional teams too much, such as the training methods of professional athletes in sports schools. The selection and training system of professional athletes are different. They begin to receive basic training of various specialties before they are 10 years old. After climbing to the provincial team, they have been trained for nearly 10 years. It is purely uncomfortable to copy and use the training plan of professional athletes. For example, Tian Tao did not practice much strength in the first three years of joining the provincial professional team, but jumped for three years. If you want to follow the current training system of others, you can jump for three years first. The same is true for other sports. The foundation and talent are different. Don't think that the advanced training method of professional teams is the unique martial arts in the world. A professional training system and the promotion and popularization of sports are basically two different things.

Super factory viruses can exploit software vulnerabilities in the form of "zero-day vulnerabilities" (zero-day vulnerabilities are also called zero-time difference attacks, which refer to security vulnerabilities that are maliciously exploited immediately after being discovered). The virus will quietly infect a system, and the user does not need to do anything specially to make the virus worm take effect, such as accidentally downloading a malicious file. Moreover, it is not only spreading in Iran's nuclear system, this worm virus can spread through Windows systems all over the world. To some extent, this is because, in order to enter Iran's system, attackers infected computers outside Iran's network system with viruses (but these computers are believed to be connected to them), so that these computers can act as "carriers" of viruses.
