- Abstract
- Success in designing affordable automated control systems for aquaculture will be widely applicable because it will enhance water management. Intensive recirculation systems have the potential for a significant increase in production per volume of water requiring dissolved oxygen monitoring and control. An intelligent Lab View dissolved oxygen sensing unit was designed using only one oxygen sensor and its transmitter for monitoring several tanks. Peristaltic pumps extracted water from each tank without adding oxygen to the sample. Measurements were auto-calibrated and statistically diagnosed using the air dissolved oxygen measurements. Dissolved oxygen sensor membrane fouling from algal blooms, sediments or suspended water droplets still attached to the membrane at the moment of oxygen measurements in the air were analyzed; the system controlled membrane fouling problems. Dissolved oxygen changes with temperature and fish feeding were analyzed from three tanks having each carps in a different growth stage. Dissolved oxygen mass balance was studied to gain a better understanding of events which can contribute to low dissolved oxygen concentration, such as heavy plankton blooms and high temperature.
