In-Situ Fiber Optic Chemical Sensors for Freshwater Aquaculture

淡水水产养殖系统需要改进监测水质的仪器。闭环水质控制将为这个不断发展的全球行业提供额外的优势。拟议方案的目标是发展监测和控制淡水水产养殖水质的系统。这些系统将基于新型光纤化学传感器或光电极的使用。这种类型的传感器特别适合于对水溶液进行连续原位监测的要求。根据该计划将开发的系统有望提高水产养殖的增长率、生产力和环境安全设施的效率。在第一阶段方案中，将评估淡水水产养殖对化学传感器的需求。将在实验室中设计、制造和校准氨光极。然后，该传感器将在循环水系系统中进行评估。将开发用于检测需求评估中确定的其他化学物质或水参数的化学传感器的概念。此外，还将拟订一个监测和控制淡水水产养殖系统水质的系统概念。

Freshwater aquaculture systems have requirements for improved instrumentation to monitor water quality. Closed loop control of water quality will provide additional advantages to this growing worldwide industry. The objective of the proposed program is to develop systems to monitor and control water quality in freshwater aquaculture. These systems will be based on the use of novel fiber optic chemical sensors or optrodes. This type of sensor is especially well suited to the requirements of continuous in-situ monitoring of aqueous solutions. The systems that will be developed under this program promise to increase aquaculture growth rates, productivity and efficiencies in environmentally safe facilities. In the Phase I program, the requirements for chemical sensors in freshwater aquaculture will be assessed. An ammonia optrode will be designed, fabricated, and calibrated in the laboratory. This sensor will then be evaluated in a recirculating aquasystem. Concepts for chemical sensors to detect other chemical species or water parameters identified in the requirements assessments will be developed. Additionally, a concept for a system that will both monitor and control water quality in freshwater aquaculture systems will be developed.
