Tracking Walleye in Hamilton Habour

Written by Jill Brooks, 2016 MSc. Larkin co-Awardee, follow her on Twitter too, @jillbrooks85! I am currently an MSc student, supervised by Dr. Steven Cooke in the Fish Ecology and Conservation Physiology Lab at Carleton University in Ottawa. My research focuses on the movement of fish in response to various habitat restoration efforts in Hamilton Harbour at the western end of Lake Ontario. The aquatic ecosystem in the Harbour has been degraded over the last 120 years as a result of industrialization and land use change. Sewage, fertilizers and industrial pollutants flowing into the relatively small system, combined with extensive physical habitat alteration has resulted in Hamilton Harbour deemed as an […]

Freshwater Fish Survey

Hello,   As a part of a research project in the Mandrak lab at the University of Toronto Scarborough, we are testing the reliability of freshwater fish identification based on photographs of fish viewers. To do this, we are looking for volunteers to participate in surveys where participants will be asked to identify fishes based on images.  If you are interested in aiding our research and exercising your fish ID skills, please read on.   To minimize the time commitment of survey takers, we have prepared 20 short (~10 min) surveys, each with 5 different images. Each image contains a group of small freshwater fishes of varying species composition caught in Canada. As […]

Ph.D. & M.Sc. – Habitat Offsetting for Freshwater Fishes in the Oil Sands Region of Alberta, Canada

Enthusiastic, team oriented, and self-motivated students are encouraged to apply for a Ph.D. and MSc positions to conduct research on habitat offsetting for freshwater fishes in the Oil Sands Region of Alberta, Canada. This project is a multi-disciplinary collaboration between the University of Alberta, and industrial and government sponsors. Main project goals include: i) identifying food-web dynamics of newly created compensation lakes, ii) determining best practices in monitoring and measuring newly created compensation lakes, and iii) developing field based studies to determine causative relationships between age and growth and other life history characteristics in relation to differing lake environments. These research projects are fully funded and will provide key insights […]

CO2 Fish Barriers Re-blogged from the Fisheries Blog

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.

Research News

By Bryan Maitland, Ph.D. Candidate, University of Wyoming   In the boreal forest – Canada’s largest biome that in conjunction with its circumpolar counterparts in Russia and Alaska contain the largest collection of lakes, rivers, and wetlands in the world – industrial activities related to the exploration and development of natural resources have created large networks of roads and in turn the construction of hundreds-of-thousands of stream-crossing structures. Due to the highly dynamic and stressful environment in which boreal fishes live (e.g. long cold winter and short growing seasons), they are extremely sensitive to additional anthropogenic stressors. Watersheds in west-central Alberta are an ideal example of this, particularly as they […]

Larkin Awardee Research Write-up

By Vivian M. Nguyen, 2014 PhD Larkin Award Winner From animal movements to knowledge movements: Knowledge mobilization associated with rapid developments in electronic tagging technology and its application I am currently a PhD student in the Biology Department at Carleton University. I wouldn’t say that my research project is a typical one you would find within a biology department; instead, I am pushing the boundaries a bit, and taking on a more social science slant. My research focuses on addressing the gap between science and action, and understanding the movement of knowledge in the context of improved conservation through informed decision making. I am using knowledge produced from electronic tagging […]

Last January, all rivers led to Rome

“This week, all rivers lead to Rome,” said Mr. Arni Mathiesen, Assistant Director-General, FAO Fisheries and Aquaculture Department, in his opening remarks of the Global conference on Inland Fisheries. Last month in Rome the first global conference on inland fisheries was held . The role of inland fisheries is significant, yet underestimated on a global scale. For the first time scientists, policy makers and international development community gathered together to discuss and address the economic and ecological challenges related to freshwater fisheries around the globe, with a common goal to raise the profile of inland fisheries. The conference was organized into four themes (each with its own panel): Biological Assessment, Economic […]

Postdoc Opportunity at University of Illinois

Description We are seeking a highly motivated post doctoral research associate for the Department of Natural Resources and Environmental Sciences (NRES) at the University of Illinois. The associate will participate in a large, long-term research program quantifying the impacts of elevated aquatic carbon dioxide on aquatic organisms. The current opportunity is for a 3-year project that will quantify the movement, behavior, and spatial ecology of freshwater fishes following exposure to elevated aquatic carbon dioxide. Work will consist of both laboratory simulation experiments, as well as large-scale field studies with fishes in experimental ponds. Work will be conducted in collaboration with a number of federal partners including researchers from the US […]
