Surgically implanting an acoustic tag into an invasive carp to investigate movement patterns.
Hi there - my name is Jordanna and I'm a dual Canadian-American aquatic ecologist and conservation scientist currently based in eastern Ontario, Canada. My love for the outdoors fueled a passion to protect and conserve our natural world, and encouraged my desire to pursue a career in conservation research. I have had the privilege to hold a variety of conservation-focused positions across North America: from kelp forest ecologist, to professional and scientific diver, to marine fisheries biologist, my efforts have been consistently focused towards the conservation of our world's aquatic ecosystems.
My past research and professional roles focused primarily on the marine environment; for my PhD, I've turned my attention to freshwater ecosystems, which need our help now more than ever. Freshwater biodiversity is rapidly declining, with freshwater species extinctions occurring faster compared to marine and terrestrial ecosystems. Roughly 8,000 freshwater-dependent species are threatened with extinction; 28% of those being freshwater fishes. For my dissertation, I am investigating the ecological connectivity of a freshwater historic waterway as experienced by both native and invasive fish species. Our goal is to determine the seasonal, species-specific, and ecohydraulic drivers of fish movement patterns within the waterway itself and between anthropogenic barriers (i.e., locks, dams). Using an interdisciplinary and integrative approach, we aim to use results from my dissertation to support conservation actions and develop strategies to protect and enhance Ontario’s economically important, and beautiful, freshwater ecosystems.
Although my past research experiences have provided me with a strong scientific background, graduate school has offered a special chance to continue to learn and grow as a researcher, and person. My research is co-supervised by Drs. Steven Cooke and Joseph Bennett, and is supported by the Natural Sciences and Engineering Research Council of Canada (NSERC PGS-D), Parks Canada, and Carleton University.

A fun, autumn field day on Big Rideau Lake, Ontario.
In interconnected freshwater systems like waterways and historic canals, ensuring connectivity across the landscape can stem biodiversity losses by enhancing migratory populations, supporting genetic diversity, and providing access to ideal critical habitats. However, these waterways are often plagued with anthropogenic river fragmentation and connectivity loss because of barriers like navigation locks and dams, and the diffusion and consequential negative effects of invasive species. Selectively managing barriers in waterways to promote the movements of native species while simultaneously minimizing invasive species dispersal – a conservation strategy known as 'selective fragmentation' – could provide a solution, but is a major challenge.
Located in eastern Ontario, Canada is the Rideau Canal Waterway, one such waterway that embodies this challenge. It is a 202-kilometre continuous navigable route that forms a connection between the Ottawa River, at Canada’s capital city of Ottawa, and Lake Ontario, at the city of Kingston. Although the waterway was originally constructed in the 1830s for commercial shipping and national defense, today it is primarily operated for recreation by the federal agency Parks Canada and for its international significance as a UNESCO World Heritage Site. The waterway features large and small lakes, riverine areas, and constructed channels all interconnected by 46 operating navigation locks, many of which have water-control or hydroelectric dams (collectively, 'lockstations'). Because waterways with anthropogenic barriers – like lockstations – have been referred to as 'invasion highways' for aquatic species, it is vital to consider how infrastructure and operations could be refined to reduce invasive species spread. To do so, and without compromising connectivity for native species, we must first assess the extent that both native and invasive fishes move throughout the waterway and the ecological and/or hydraulic factors influencing movements.
With much help from peers, professors, and field assistants, I am externally (FLOY tag) and internally (acoustic tag) tagging thousands of fish across the Rideau Canal Waterway. It is currently unclear to what extent fish movement occurs at the site of individual locks and dams, or if seasonal movement patterns exist within confined reaches of the system. Do fish attempt to make reproductive migrations through barriers but are blocked? Are movements species-specific? Could lock operations and/or infrastructure be refined to reduce invasive species spread with no impact to native species? These are some of the research questions we are focusing our efforts towards answering. Given that anthropogenic waterways are pervasive worldwide, our goal is for this research to not only inform the conservation and management of the Rideau Canal, but also of other waterways in Canada and beyond.
Read about our preliminary findings in a fun magazine article here.
To develop and implement successful management strategies that simultaneously restrict and enable movements of invasive and native species, respectively, an understanding of movement patterns and the drivers of movements is necessary. We are acoustically tracking three recreationally-important native fish species, largemouth bass, muskellunge, and northern pike, and two invasive fish species, common carp and round goby.
Although external tagging does not provide the same level of fine-scale movement data as acoustic telemetry, it offers a way to tag thousands of fish quickly and use recapture locations to understand broad movement patterns. To date, we have externally tagged ~9,500 fish throughout the waterway, and will continue until we reach our goal of 10,000 tagged fish. With the generous help of anglers who report tagged fish they've caught, we can track the movements of tagged fish for as long as they're swimming (we mark, you recapture!). If you've caught a tagged fish or would like more information, please contact me at firstname.lastname@example.org.
