This week the Fisheries Blog describes how carbon dioxide can be used as a barrier for fish movement. This work should be of particular interest to CARS members, as there is hope that this technology could be used to prevent Asian carp, like Silver and Bighead Carp from entering the Great Lakes via the Chicago Sanitary and Shipping Canal. Also, much of the ‘proof of concept’ work and followup studies are being completed by CARS members led by Cory Suski at the University of Illinois.
Summer Field Assistants NeededApril 18, 2018
Positions: Two Arctic Field Research Assistants Duration: ~August 6 to ~ August 27, 2018 Location: Inuvik and Tuktoyaktuk, Northwest Territories Stipend: $2,100 for the three-week duration. All costs related to travel, food and accommodations are additionally covered. Description: Our study area is in a unique region of northern Canada, where Canada’s first all-season highway connection to the Arctic Ocean has just opened to the public. This August, our research team will be collecting fish population data in lakes between Inuvik and Tuktoyaktuk, NWT. The research program is a joint effort led by Dr. Derek Gray (Wilfrid Laurier) and Dr. Sapna Sharma (York University) investigating the effects of climate change on […]
Larkin Award Runner-up: Sarah WaltonApril 12, 2018
By Sarah Walton, M.Sc. candidate, Carleton University I am an MSc candidate co-supervised by Dr. Steven Cooke in the Fish Ecology and Conservation Physiology Laboratory at Carleton University and Dr. John Farrell from the State University of New York (SUNY) College of Environmental Science and Forestry (ESF). My research investigates spatiotemporal and behavioural ecology of age zero esocids – Muskellunge (Esox masquinogy) and Northern Pike (Esox lucius) – in the St. Lawrence River. Exploring the spatiotemporal ecology of fish is necessary to elucidate life history strategies, delineate and conserve core habitats, and appropriately manage populations. While nursery habitat requirements for age zero esocids in the St. Lawrence River are well […]
Larkin Award Runner-up (PhD) – Michael LawrenceApril 10, 2018
By Michael Lawrence My current body of work looks to address the role of the stress axis in mediating predator-prey interactions in wild fishes. My research primarily focuses on the biology of pumpkinseed (Lepomis gibbosus) in the Rideau Lakes region. Specifically, I’m looking to characterize the physiological consequences of sustained cortisol elevation on the metabolic operation of pumpkinseed and to link these alterations with behavioural parameters that are indicative of anti-predator capacity and/or risk aversion. During my research, I will also be quantifying the influence of cortisol on altering predation rate in a mesocosm setting thereby linking physiological, behavioural and ecological scale processes together to thoroughly address the question of […]
