ABSTRACT: The connectivity of aquatic environments facilitates the exchange of microbial pathogens among and between wild and farmed fish stocks, thereby leading to disease events and subsequent mortality. Such exchanges can occur through many means, including the stocking of infected individuals, through source and effluent water, and through infected gametes/reproductive fluids, and can occur in both directions (i.e., wild to domestic stocks and vice versa). In addition, a multitude of factors impact the rates and effects of fish-pathogenic microbe transmission, some of which can be dramatically altered, both positively and negatively, through fish culture and biosecurity practices. Herein, we will utilize a number of case studies to illustrate some of the primary issues surrounding the interactions of wild and domestic fish stocks as they pertain to pathogen transmission dynamics and resultant disease. The challenges impeding our ability to mitigate these issues, including the absence of fish health infrastructure in most Great Lakes States and the dearth of knowledge on the biology and pathogenic properties of many microbes affecting aquatic organisms, will also be discussed.
