The Society of Canadian Aquatic Sciences each year makes
calls for a number of award nominations to recognize the
best and brightest among our field, and to support
student travel to our annual meeting.


2023 Recipient/Récipiendaire de l'année 2023

Dr. Beatrix Beisner

Professor, Department of Biological Sciences/ Département des Sciences Biologiques
University of Quebec at Montreal/ l'Université du Québec à Montréal , QC

The 2023 Rigler awardee is Dr. Beatrix Beisner, professor at the University of Quebec at Montreal. Her research focuses on plankton community ecology, with research themes encompassing biodiversity and invasion ecology. Over her research career so far, Dr. Beisner has trained 14 postdoctoral fellows, 24 PhD students, and 28 MSc students, and published over 100 peer-reviewed articles that have had lasting impact on the field. Some of Dr. Beisner’s most significant contributions include work on aquatic community dynamics as they relate to climate change and the application of functional ecology in planktonic communities. Her paper on alternative stable states in ecology (Beisner et al. 2003) has been particularly well cited across disciplines. Dr. Beisner is an established leader in Canadian limnology and is currently the co-director of the Groupe de Recherche Interuniversitaire en Limnologie et Environnement Aquatique (GRIL) and has been instrumental in organizing annual meetings, collaborative research projects, and providing access to critical infrastructure for limnological research. The research that has emerged from GRIL is renowned across Canada and globally.

La gagnante du prix Rigler 2023 est Docteure Beatrix Beisner, une professeure à l'Université du Québec à Montréal. Ses recherches se concentrent sur l'écologie des communautés planctoniques, avec des thèmes de recherche comprenant la biodiversité et l'écologie des invasions. Au cours de sa carrière scientifique, Docteure Beisner a entraîné 14 boursiers postdoctoraux, 24 étudiants en doctorat et 28 étudiants en maîtrise et a publié plus de 100 articles révisés par des pairs qui ont eu un impact considérable dans le domaine de la limnologie.

Frank H. Rigler


The Frank H. Rigler Award was first presented in 1984 to recognize and honour major achievements in the field of limnology by Canadians or those working in Canada. Emphasis in selection is given to established aquatic scientists with a proven record of contribution to the field of aquatic sciences, and whose work is widely recognized for its influence and importance. The winner of the award will give an overview on their research during the plenary session of the Society of Canadian Aquatic Sciences annual meeting and will receive complimentary registration at the meeting and a one-year membership with the Society. 

Frank Harold Rigler (1928-1982) was an accomplished aquatic biologist who helped shape the field of limnology in Canada. He was a professor at the University of Toronto (1957-1976) and Professor and Chair of the Biology Department at McGill University (1976-1982).

2023 Peters Award Recipient

Graydon McKee

The winner of the 2023 Peters Award is Graydon McKee, a recent graduate from Lakehead University. Graydon’s paper titled, “Alternative migratory strategies related to life history differences in the walleye (Sander vitreus)” was published in Movement Ecology (McKee et al. 2022). In the words of Graydon’s nominator, “Graydon’s work stands to make a significant contribution to understanding the inherent variation that exists within managed populations like fisheries, indicating that management strategies targeted at “a population” without recognizing this variation is unlikely to succeed, or alternatively, only potentially benefit one fraction of the population”.

Le gagnant du prix Peters 2023 est Graydon McKee, récemment diplômé de l'Université Lakehead. L'article de Graydon est intitulé " Stratégies migratoires alternatives liées aux différences de cycle biologique chez le doré jaune (Sander vitreus) " et a été publié dans le journal Movement Ecology en 2022. Selon la personne qui a proposé la candidature de Graydon, "le travail de Graydon contribuera de manière substantielle à la compréhension de la variation inhérente qui existe chez les populations régulées par les pêcheries, indiquant que les stratégies de régulation visant "une population" sans tenir compte de cette variation peuvent être inefficaces ou, au contraire, de ne profiter qu'à une fraction de la population".

The Robert H. Peters Award recognizes the best aquatic sciences paper published in the preceding year by a Canadian student or a student working in Canada. The student must be an undergraduate or graduate student and must be first author on the publication.

The value of the award is $500 and a complimentary one-year membership to the Society of Canadian Aquatic Sciences. The award is presented at the annual Society meeting at which time the awardee presents a summary of their paper.

Robert Henry Peters was an accomplished aquatic ecologist who made novel contributions to limnology, particularly in the fields of phosphorus cycling and predictive ecology.

2022 Stevenson Award Recipient

Chelsea Rochman

Assistant Professor
Department of Ecology & Evolutionary Biology
University of Toronto

The Stevenson Lectureship is a prestigious lectureship instituted in memory of Cam Stevenson, the long-time Editor of the Canadian Journal of Fisheries and Aquatic Sciences (CJFAS). The lectureship is conferred upon a young, energetic, and creative researcher at the cutting edge of an aquatic discipline.

The Lecturer delivers a stimulating presentation of their work as the keynote address in the opening session of the annual Canadian Conference for Fisheries Research (CCFFR) meeting. The Lecturer is invited to submit a manuscript, based on their Stevenson Lecture, to CJFAS.


In the Spring of each year, a call for nominations is sent to the Chairs of zoology and biology departments across Canada, as well as to the research directors of Fisheries and Oceans Canada, Environment Canada, and the National Research Council. The list of nominees is then sent to the CJFAS Editorial Board, who provide recommendations and justification for their selections.

At this time, the award is administered by CJFAS editors.

Eligible recipients of the Clemens-Rigler Travel Award include graduate students registered
in a Canadian university and Early Career Researchers who are presenting either
a poster or an oral presentation at the SCAS annual meeting.

Students planning to travel to the annual Society of Canadian Aquatic Sciences meeting can apply to the Clemens-Rigler Travel Award for funding to supplement their travel costs.

The committee attempts to distribute funds fairly among participants to conference and to foster participation from all parts of Canada. Consequently, the amounts awarded are based on available funding and are generally proportional to the cost of traveling to the conference. Awards typically range from $200 to $500.

Details on how to apply and required information can be found in the Conference section of this website.
