Thomas Durizot

Master student

My name is Thomas Durizot and I am from Guadeloupe. I have been in Quebec since autumn 2019 in order to realize my studies in oceanography at UQAR-ISMER. Before coming here, I studied in physics and chemistry to get my bachelor’s degree before turning to biological oceanography, which has interested me for a while. When I arrived at Rimouski, I first have followed the DESS in oceanography program given by UQAR-ISMER for one year before continuing my studies in the MSc oceanography in autumn 2020 under the direction of David Deslauriers.

My project is on the ecophysiology of brook trout (Salvelinus fontinalis) and more precisely on their bioenergetic potential in terms of climate change. The aim of this project is to predict the growth and metabolism of these fishes with a bioenergetic model. In order to do this, this project implies to study the growth of adult fishes and their environment using otolith and trace element analysis, as well as to conduct growth experiments on juveniles placed on different conditions (temperature or food ration).


Félix Tremblay-Gagnon

Master student

My name is Félix Tremblay-Gagnon and I am currently working on my Master’s project as a graduate student in the Laboratory of Advanced Bioenergetics (LAB). I grew up in Côte-de-Beaupré and in Charlevoix, Quebec, where I developed my passion for fishing and hunting. These activities exposed me to a broad range of natural environments, raising a strong desire to understand how they work. After college I went into the field of Forestry at Laval University. After 2 years, I reoriented myself in biology at Université du Québec à Rimouski (UQAR). In the summer of 2019, I worked as a research assistant for the Research Chair on exploited aquatic species (RCEAS) under the supervision of Dr. Pascal Sirois. While I was there, I learned a lot on research and confirmed my interest for aquatic biology and fisheries ecology.


Since May 2020, I’ve been working on my Master’s project which concerns the Greenland halibut’s diet composition in the Labrador sea.The main goal of the study will be to describe the diet of the Greenland halibut as well as understanding the predator-prey interactions between the halibut and the northern shrimp, two commercially significant species.

Andra Florea

Master student

Professional ornithologist accumulating several experiences, I am also sensitive and involved in social and political issues. Active with the Oceanography Module Council, the Oceanography Program Committee, the feminist committee of UQAR as well as Cinema Politica, I also negotiate the collective agreement of the Union of UQAR’s Student Employees. In lost time, I founded the page of the Regroupement des TechniciensNEs et Biologistes GraduéEs du Québec, a unique networking place, which I have administered since 2018 and which has more than 2,800 members. Equipped with a technique in bioecology from Cégep de Saint-Laurent, a bachelor's degree in biology (ecology) from the University of Quebec at Rimouski, I joined the Laboratory of Advanced Bioenergetics for a master's degree in Oceanography relating to an Iceland scallop (Chlamys islandica) fishery in Sanikiluaq, NU. Using several methods to quantify and qualify this stock, I will attempt to perform schlerochronological analyzes on the shells to trace the past environmental conditions of the resource and thus explore the potential impact of an excess supply of fresh water in the environment and its effect on the resource growth. During my bachelor's degree, I carried out research on the foraging impact on oxidative stress for the northern gannet (Morus bassanus) from the Bonaventure Island colony. In addition, I am currently working on a manuscript on the migratory phenology of Quebec birds for the past 50 years as well as on the irruptive migratory behavior of the White-breasted Nuthatch (Sitta carolinensis) in eastern North America.


Jordan Kroeker

Master student

I have a B.Sc. (Hon.) in Biological Sciences from the University of Manitoba. I studied competition in Cape ground squirrels (Xerus inauris) in South Africa using behavioural observations to determine the social structures within social groups. My main undergraduate research focussed on stress physiology. I studied chronic stress in Lake sturgeon juveniles caused by early-rearing conditions through evaluation of physiological factors such as growth, cortisol levels and gene expression. I also assessed the effects of thermal stress on a freshwater amphipod (Hyalella azteca) by analyzing gene expression patterns and investigated the interaction between thermal tolerance and anthropogenic impact on intertidal amphipod (Gammarus setosus) in Iqaluit, NU.


I am currently doing a Master’s student in biological oceanography at Université de Québec à Rimouski, Institut des sciences de la mer à Rimouski with David Deslauriers, Fanny Noisette and Chris Mckindsey (Department of Fisheries). The aim of my project is to create and validate a bioenergetics model, Dynamic Energy Budget (DEB) for the truncated soft-shelled clam (Mya truncate) an Arctic and subarctic species with cultural and ecological importance. My focus is on the effects of temperature on various physiological rates, including oxygen consumption, filtration, excretion and calicification. This model can be used to predict the future distribution of this species in response to changing environmental conditions in response to climate change. 


Christophe Jourdain-Bonneau

Master student

My name is Christophe Jourdain Bonneau. I started my project in September 2019 on the effect of chronic thermic stress on transcriptomic, metabolism and growth of controlled and selected descent of Salvelinus fontinalis. This project is taking part on the pancanadian Gen-Fish project. One of the objectives is the creation of an universal toolkit that can help to study the genetic expression of several species of fish in Canada.


Santiago Jarquin

Master student

My name is Santiago Jarquin. I was born in Québec, raised in California, and my parents come from El Salvador and Argentina. I obtained my bachelor’s degree in marine biology at “l’Université du Québec à Rimouski” (UQAR). After having completed a certificate in applied oceanography I am currently working on a research project with the American eel (Anguilla Rostrata) for my master’s degree at “l’Institut des sciences de la mer de Rimouski” (ISMER). The project aims to confirm the theoretical relationship between fish metabolic rate and the stable isotope ratios of carbon in fish otoliths which are carbonate structures in the inner ears of most vertebrates.  Theses structures can produce a record of a fish’s field metabolic rate from birth to death. They also allow us to recreate water temperatures of a fish’s environment throughout its whole life. These two aspects are very useful for understanding the metabolic and consequently, physiological response of these organisms to climate change and more specifically global warming. Therefore allowing fisheries to produce management plans that take into account the effect of future problems that have yet to make an impact on the current stocks.
