Amelia Mahony

Aquatic Biologist

I am involved in salmon health research. I conduct research on the various pathogens (viruses, bacteria and parasites) affecting Pacific salmon. We assess the impacts these pathogens have on the fish (at population and molecular levels) and attempt to determine the prevalence within our salmon populations.

Current research and/or projects

My research involves looking at pathogens that affect both wild and farmed salmonids. Examples of these pathogens include Myxobolus arcticus, Kudoa thyrsities and Sea lice. We look at the effects, both clinically and sub-lethally that these pathogens have on these fish. Currently, I am developinig quantitative PCR methods (using a probe to detect specific sequences of DNA) to determine the prevalence of several microsporidia parasties in Pacific salmon. These parasites are typically found in the gills of salmon and with high infection levels, can impede gill function.

Research and/or project statements

Our research contributes to further understanding of the health of our Pacific salmon stocks as well as to the biology of the pathogens that infect them. All Canadians benefit from maintaining healthy salmon stocks which are essential indicators of healthy ecosystems.
