The invention discloses a 4G-based intelligent fishery management system and belongs to the aquaculture related technical field. The system comprises a monitoring system; the output end of the monitoring system is in signal connection with a LORA wireless controller; the output end of the LORA wireless controller is in signal connection with a 4G route controller; the output end of the 4G route controller is electrically connected with a communication terminal; the output end of the communication terminal is electrically connected with a GPRS chip 4G communication module and a server; and theoutput end of the GPRS chip 4G communication module is electrically connected with the server. The system of the invention is reasonable in design, powerful in function, stable in operation and easy to popularize. According to the system, a modularized mode is adopted, so that equipment is convenient to maintain and manage; and on the basis of a plurality of Internet of Things devices such as a water quality sensor, a controller, a waterproof camera and a temperature sensor deployed in a fishery, and by means of a remote monitoring center and a mobile monitoring terminal, the real-time monitoring and automatic alarm reminding of the environment indexes of the fishery are realized, and the phenomenon that a large number of fishes die is avoided.
