About

MY BACKGROUND

Hi there - my name is Jordanna and I'm an aquatic ecologist and conservation scientist 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 thesis, I am investigating the ecological connectivity of a freshwater historic canal as experienced by both native and invasive fish species. Our goal is to determine the seasonal, species-specific, and/or hydraulic drivers of fish movement patterns within the waterway itself and between anthropogenic barriers (i.e., locks, dams). Using a multidisciplinary and integrative approach, we aim to use results from my thesis 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 supported by the Natural Sciences and Engineering Research Council of Canada (NSERC PGS-D), Parks Canada, and Carleton University.

Current research 

The Rideau Canal, located in eastern Ontario, Canada, forms a 202-km continuous navigable route between Lake Ontario and the Ottawa River, and is interconnected by 24 lockstations. When the Rideau Canal was constructed in the 1830s, previously disconnected aquatic habitats were connected, enabling movement through barriers to both invasive and native species. As invasive species pose one of the greatest threats to the biotic integrity of freshwater ecosystems, with potentially adverse socio-economic effects on human welfare, it is vital to consider how infrastructure and operations could be refined to reduce their spread. To do so, and without compromising connectivity to native fish species, we must first assess if, when, and to what extent native and invasive fish move throughout the waterway and the potential factors driving movements.  

With much help from peers, professors, and field assistants, I am externally (FLOY tag) and internally (acoustic tag) tagging thousands of fish in the Rideau Canal. 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. To date, no research has been conducted to simultaneously model movement patterns of native and invasive species in the Rideau Canal to inform conservation decisions and protect aquatic biodiversity. Given that anthropogenic waterways are pervasive worldwide, this research informs not only the conservation and management of the Rideau Canal, but also of other waterways in Canada and beyond.

Acoustic telemetry

To develop and implement successful management strategies that simultaneously restrict and enable movements of invasive and native species, respectively, an understanding of the drivers of movements is necessary. We are currently examining the movement patterns of three recreationally-important native fish species, largemouth bass, muskellunge, and northern pike, and two invasive fish species, common carp and round goby, through the use of acoustic telemetry. 

Mark-recapture 

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 ~6,500 fish throughout the Rideau Canal, 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 carleton.tag@gmail.com.
