System for oxygen measurements in a fish farm

The most important variable for intensive fish farming is the ability to monitor the oxygen concentration in the water in an autonomous and continuous fashion. We report on a system capable of remote data collection that was deployed in fish pond. The system is capable of tracking the dynamic changes in oxygen concentration encountered in during facility operation. A user friendly computer interface provides output from the sensor located in the fish pond and enables setting alarm levels, which are communicated to the farmer via a commercial cell phone network.
