Aquafarm and hatchery managers, transporters and researchers make decisions regarding fish health based on water quality. Water quality management is an essential tool for any aquaculture operation and is affected by variables that can drastically affect fish health and production procedures. Aquasend®, a brand of Precision Measurement Engineering, has introduced the miniDOT® Clear Logger to researchers and managers in various segments of aquaculture as a reliable, easy-to-use logge r with quick access to data.
The miniDOT® Clear Logger is a completely submersible instrument that records measurements in real-time displayed through an internal LCD screen, granting quick access to water quality data. The oxygen sensor is an optode that measures dissolved oxygen concentration in water through a fluorescence method. These features allow users to view vital water quality data just by looking at the device to save valuable time if dissolved oxygen or temperature levels begin to rapidly shift.
During my presentation, I will give an overview of the miniDOT® Clear and the feedback we have experienced s ince its introduction to aquaculture and the three major uses that have emerged. Aquatic transport is one segmen t where the logger is proving to be an essential tool. No matter the fish species being transported, from largemouth bass to tilapia or even sturgeon, it is crucial to maintain proper oxygen levels and temperatures. Each fish species has unique habitat requirements most often revolving around dissolved oxygen levels and temperature. The logger is currently being used by transporters who do not have the resources to invest in trucks and tanks equipped with oxygen systems. These transporters have utilized the logger to quickly monitor water quality levels, therefore reducing fish stress levels and ensuring a quality product upon arrival.
Other use scenarios include aquaponics systems where monitoring water paraments of dissolved oxygen and temperature is essential to maintain conditions for both fish and plants. Low DO threatens the health of fish and the quality and quantity of plants grown. These same researchers have also identified the portability and visual access to water quality data during the research process, whether in the field or in the lab. The Logger has proven to be an essential tool to not only collect water quality data but to aid researchers and their students in accessing water quality in real-time while affording the ability to reac t based on quality data.
