Indicates the oxygen supply time set by the system. Indicates the growth rate of the target area of the aquaculture pond. According to the calculated oxygenation speed of the required oxygenation equipment, the corresponding equipment operating power is retrieved from the database, and the equipment is started for oxygenation according to the equipment operating power. Otherwise, the system continues to detect.

A water quality measurement and control system for fishery farming according to claim 6, characterized in that: In step S33, the predicted value of the ammonia nitrogen concentration in the breeding pond is obtained and compared with the database. When the ammonia nitrogen concentration is greater than the system set threshold, the oxygen capacity of the breeding pond is detected. If the oxygen capacity is consistent with the parameter standard, the corresponding feed reduction amount in the database is retrieved according to the difference between the ammonia nitrogen concentration and the parameter standard, and the feed amount is reduced. Otherwise, the oxygen supply equipment is started to compensate the oxygen in the breeding pond.

It indicates the rated speed of the unmanned sprayer. According to the flight speed of the unmanned sprayer, the best spraying route is planned for the unmanned sprayer to spray the water quality regulator on the target area.
