Legal analysis: It is not illegal to breed eels. If you use illegal techniques, you will be punished after being reported by others. Punishment standards vary from place to place. For example, electric fishing is prohibited by the state and there are serious security risks. A little carelessness may lead to an accident. The Fisheries Bureau is a relatively obscure department in China, and basically it will not take the initiative to enforce the law. As long as no one reports it, it will be fine.

Legal basis: Article 38 of the Fisheries Law of People's Republic of China (PRC) stipulates that those who use methods such as fried fish, poisonous fish and electric fish to destroy fishery resources, violate the provisions of closed fishing areas and periods, or use prohibited fishing gear, fishing methods and nets smaller than the minimum mesh size, or catch young fish in excess of the prescribed proportion, the catch and illegal income shall be confiscated and a fine of less than 50,000 yuan shall be imposed; If the circumstances are serious, the fishing gear shall be confiscated and the fishing license shall be revoked; If the circumstances are particularly serious, the fishing boat may be confiscated; If a crime is constituted, criminal responsibility shall be investigated according to law.
