Graduate Student Opportunity at University of Manitoba

A position is available for a graduate student to examine fisheries issuesrelating to fleet dynamics beginning as early as September 1st 2016 (applications due March 1st). This work will be based in the Department of Biological Sciences at the University of Manitoba, but may involve travel to coastal areas for research collaboration. Funding for this position is available through my NSERC Discovery Grant and the University of Manitoba’s GETS program. Funding for students holding external awards will be supplemented, as allowed by the conditions of their award and available funds.

Thesis work will be in support of my research program, focusing on fisheries in Canada (freshwater and marine) and abroad (marine) through ongoing collaborations with provincial, national, and international agencies. Briefly, this program involves the detailed quantitative examination of fish and fishing activities with the goal of improving population estimation and the application of management practices. This M.Sc. project will include aspects of fish population dynamics, harvest strategies and tactics, and the development of novel quantitative analyses (statistics and models) to address the impacts of fisher behaviours within the fishery system.

Previous students have continued in graduate studies or found employment as biologists with the Department of Fisheries and Oceans (Atlantic and Central Canada), First Nations (resource management boards in the Northwest Territories) or NGOs (such as the International Institute of Sustainable Development – Experimental Lakes Area).
Current student projects in my laboratory include: non-linear relationships between catch and nominal effort, the impacts of species targeting on stock assessments, and the application of agent based modelling to the effort dynamics in a fixed gear fishery.

Representative publications fromthis research program include:
