Evaluating Gradients of Natural and Induced Stress on Fish Blood Parameters; Developing more accurate results from Point-of-Care Devices

The point-of-care i-STAT and VETSCAN units are easily portable blood-based assessment tools that can produce relevant blood parameters within minutes with only 2-3 drops of blood. The objective of this study is to examine both natural and investigator-applied stress gradients in fishes and compare blood chemistry of fishes from a range of environments (e.g., low to high stress). Investigations will occur in the lab and in the field at IISD- Experimental Lakes Area (ELA), where field data from devices will be compared to standard laboratory methods in the University of Manitoba in order to produce a point-of-care instrument better suited for fish. With the completion of this project, IIED-ELA will have greater knowledge about the current fish population within lakes, as well as access to devices that can be used in the field collect fish health data.
