Development of Opto-Chemical CO2 Sampling/Monitoring System Suitable for Aquaculture Applications

Aquaculture has become a critical component in the international quest to feed the world and protect the earth¿s natural food resources. Numerous research efforts have proven that controlling CO2 in aquaculture is critical to the quality and quantity of the product produced. Though the importance of controlling CO2 levels in all aquaculture environments (re-circulation systems, ponds, ocean settings, etc.) is well established, there are no suitable means for regularly monitoring dissolved CO2 in these waters. We propose to develop an opto-chemical CO2 monitor which is sufficiently robust, sensitive and accurate to serve all aspects of the aquaculture market by providing fast, reliable dissolved CO2 readings on demand with a view to optimizing aquaculture operations and increasing the quantity and quality of their end product. Severinghaus described the principle for a CO2 sensor. We propose to modify this approach by optimizing the sensor¿s chemistry making it suitable for aquaculture.
