The closed fishing season refers to the period stipulated by the government to prohibit or restrict marine animal fishing activities. Its purpose is to protect the normal growth or reproduction of aquatic organisms and ensure the sustainable recovery and development of fish resources.

It is a universal system to protect fish resources in all countries of the world to stipulate the closed fishing period, and this system is also clearly stipulated in China's fishery laws and regulations. According to China's fishery law and other laws and regulations, the fishing ban period is stipulated by the fishery administrative department of the people's government at or above the county level.

Fishing ban refers to the period when fishing of a certain fishery resource or a certain type of operation mode is completely or partially prohibited in the specified production waters. This is an important measure to protect fishery resources. It has the same nature as the closed fishing season, except that the closed fishing season limits the waters and the closed fishing season limits the time.
