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 British Columbia, 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 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. My doctoral research investigated 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 across barriers (i.e., navigation 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. My PhD was co-supervised by Drs. Steven Cooke and Joseph Bennett, and supported by the Natural Sciences and Engineering Research Council of Canada, Parks Canada, and Carleton University. 

Currently, I'm an Aquatic Conservation Scientist with Parks Canada. My work here focuses on developing a review of the effectiveness of no-take protection zones in large lake ecosystems. Additionally, I'm working to bridge the "knowledge-action gap" by collating research outputs from a large-scale grant to provide managers with actionable conservation recommendations. 


I am also an incoming postdoctoral fellow (April 2024) at the University of Victoria where I will be working with Drs. Maycira Costa and Anne Salomon to evaluate the spatial-temporal dynamics of kelp-encrusting bryozoans across British Columbia's coast.

Current research

Doctoral research 

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 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 externally (FLOY tag) and internally (acoustic tag) tagged thousands of fish across the Rideau Canal Waterway, discovering several interesting findings. Our movement data suggests that lockstations reduce, but do not entirely restrict, connectivity, and that seasonal water-level drawdowns further reduce connectivity within river reaches. We found that most fish passages were in the direction of flow, a potential issue to native upstream migratory species. Notably, while we documented several native fish species crossing barriers, no invasive common carp passages were detected and only a single invasive round goby moved upstream through a lock. Results from my doctoral work add to the limited, but growing, literature base of native and invasive fish movements in waterways, providing evidence and suggestions for managers and conservation groups to develop selective fish passage strategies or take restorative actions. Given that waterways are pervasive globally, our hope is that this research informs not only the conservation and management of fish populations in the Rideau Canal Waterway, but of other waterways in Canada and beyond.

Acoustic telemetry

Study species.png

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 first needed. We acoustically tracked 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 almost 10,000 fish throughout the waterway. 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
