ABSTRACT: There are many diseases in freshwater fish of the Great Lakes region. Most of the research that has been completed focus on hatchery fish, and the wild disease etiology is unknown. This study was conducted to survey the healthy status of the fish using 3 tributaries into the Whitefish Bay of Lake Superior and to observe the diseases carried by migrating species. 15 fish from each species were collected from each stream; a bacterial swab, blood, and internal organs were taken from each fish. The hematological parameters (blood cell counts, hematocrit, and hemoglobin) were analyzed in the blood samples. The potential pathogenic bacteria and viruses which cause common diseases like BDK, Furunculosis, Cold Water Diseases, and VHS were diagnosed in the collected bacterial swab, blood and internal organ samples by using ELISA. Some preliminary data shows that there is no difference between hematological parameters of fish going upstream to spawn and fish coming downstream after spawning. Only some individual fish have abnormal hematocrit and blood cell levels. More details on the carried pathogens, as well as the health status are still under investigation.
