①闻味道：尽量不要买那种闻起来有酸臭味、氨水味儿的鱼。
②看鱼眼：尽量买鱼眼是清晰明亮、有一点鼓起的鱼。
③看鱼鳃：尽量买鱼鳃是鲜红色的鱼。
④看背部肌肉：尽量挑选鱼背有弹性（弯了能收回的）的鱼。
注意：现杀的活鱼，可以先放冰箱冷藏2小时，经历了排酸过程再烹饪。
被你丢弃的“宝贝”
杀鱼的时候，很多人最痛恨的就是鱼鳞，腥味重、还硬，往往“除之而后快”。但其实鱼鳞不仅能吃，营养价值还很高！
1、卵磷脂
鱼鳞中含有较多的卵磷脂，其能增强大脑记忆力、延缓细胞衰老。
2、不饱和脂肪酸
能帮助胆固醇代谢，调节血液中脂肪和胆固醇的含量。
①先将鱼鳞放入漏勺，用清水冲洗干净，沥去水分，放入干净的容器；
②葱切段、姜切片放在鱼鳞上，并撒上一小勺盐，接着加入清水（水量没过鱼鳞约1cm）；
③水开后，放入锅内中火蒸25-30分钟；
④将蒸好的鱼鳞过滤，取滤汁晾凉，用容器盛起，放进冰箱冷藏2小时以上；
⑤鱼鳞冻成型后是晶莹剔透的，可以加黄瓜丝、少许蒜末和香油凉拌，也可以直接蘸酱。
The Ministry of Human Resources and Social Security, the General Administration of Market Supervision, and the Bureau of Statistics jointly released new occupational information, including artificial intelligence engineering and technical personnel, IoT engineering and technical personnel, big data engineering and technical personnel, cloud computing engineering and technical personnel, digital management engineers, and building information model technicians. E-sports operators, e-sportsmen, drone drivers, agricultural managers, IoT installation and commissioners, industrial robotic systems operators, industrial robotic systems operators and other 13 new occupations.
On April 1, 2019, the Ministry of Human Resources and Social Security, the General Administration of Market Supervision, and the Bureau of Statistics officially released artificial intelligence engineering technicians, IoT engineering and technical personnel, big data engineering and technical personnel, cloud computing engineering technicians, and digital management personnel. 13 new career information such as building information model technicians, e-sports operators, e-sportsmen, drone drivers, agricultural managers, IoT installation and commissioners, industrial robot system operators, and industrial robot system operators. This is the first new occupation since the promulgation of the 2015 National Occupational Classification. The Ministry of Human Resources and Social Security organizes occupational classification experts, which are selected in accordance with the new professional assessment standards and procedures, and are selected from the new occupational proposals submitted by the relevant reporting units, and are widely publicized after consultation with the public. The first batch of new occupations are mainly concentrated in the high-tech field, with the following characteristics:
The upgrading of the industrial structure has spawned a new career in high-end professional technology. At present, China's economy has shifted from a high-speed growth stage to a high-quality development stage, which puts new demands on the scientific and cultural quality and ability level of workers. In recent years, with the extensive use of artificial intelligence, Internet of Things, big data and cloud computing in China, the high-tech industry related to this has become a new growth point for China's economy. The demand for employees has increased significantly, forming a relatively stable working population. Four professional and technical new occupations, such as artificial intelligence engineering technicians, IoT engineering technicians, big data engineering technicians and cloud computing engineering technicians, came into being. These new occupations are high-tech industries, supported by high professional technical knowledge and ability, and practitioners generally have higher education.
The advancement of science and technology has triggered traditional career changes. With the adoption of emerging technologies, the traditional first and second industries are becoming more and more intelligent. The practice of industrial robots replacing simple labor on production lines has been promoted in some areas, and robot-related production, service and training companies have flourished. The large-scale use of industrial robots has dramatically increased the demand for industrial robot system operators and system operators, making it a new profession in the modern industrial production line. With the maturity of drone technology, it is possible to use drones to complete high-risk and toxic and harmful work that is difficult for humans to complete. Plant maintenance, mapping, photography, high-voltage cables and agricultural and forestry inspections can be carried out by drones. It also has a wide application space in the fields of logistics and so on. The use of a large number of drones has made drone drivers a veritable emerging profession.
The widespread application of informatization has spawned new professions. Informatization is like a catalyst, which transforms the content of professional activities in traditional occupations, and thus derives new occupations, such as digital managers and building information model technicians. With the widespread application of the Internet of Things in the fields of office and residential, the informatization and the modern manufacturing industry are deeply integrated, and the demand for the staff of the Internet of Things installation and debugging has surged. In recent years, driven by international competitions, computer-based competitive projects have developed rapidly, and e-sports has become a huge emerging industry. The professionalization of e-sports operators and e-sportsmen is imperative. In the agricultural sector, agricultural economic cooperative organizations such as farmers' professional cooperatives have developed rapidly. The demand for management services such as agricultural production organization, equipment operation, technical support, product processing and sales is strong, and agricultural managers have emerged.
