Eric Parkinson is an adjunct professor with the UBC Institute for the Oceans and Fisheries and a consultant specializing in systems analysis of freshwater ecosystems. He holds BSc (Biology 1973) and MSc (Zoology 1980) degrees from UBC and worked with the BC government Fisheries Research Section at UBC for 35 years. Most of Eric’s current work is focused on modeling and data analysis designed to quantify Performance Measures (PMs) associated with fisheries management issues in hydro power reservoirs. He is also assisting in a variety of BC Ministry of Environment (BCMOE) projects associated with management of rainbow trout fisheries in small lakes and kokanee/piscivore systems in large lakes and reservoirs.
Recent examples of his work include: 1) The development of methods to identify Temperature Sensitive streams at the landscape level by modeling stream temperatures and fish distributions using a GIS framework, 2) Modeling the impact of stocking practices and lake attributes on the distribution angling activity among lakes in the BC interior. 3) Assessing the impact of spawning channel kokanee production and the recruitment of entrained kokanee from upstream reservoirs on wild kokanee and bull trout stocks in the Arrow Lakes. 4) Performing analysis and modeling requested by the Entrainment Technical Committees associated with 10 BC Hydro generation facilities.
Eric’s work with BCMOE involved collaboration with fisheries researchers and technical advice for Regional staff of BCMOE. Research collaborators included faculty from UBC, University of Calgary and Simon Fraser University. Over the last 15 years, Eric has participated in advisory committees for 19 PhD and MSc students and the research activities of 9 additional students and post doctoral fellows. In most of these, this involvement has included in all phases of the research: project proposal, assisting in data collection and analysis, and reviewing thesis drafts. Eric has been an active participant in seminar programs and class activities at UBC including 1-2 presentations per year.

My Current Work is mostly focused on modeling and data analysis designed to quantify Performance Measures associated with fisheries management issues, mainly in hydro power reservoirs. I am also completing a variety of BCMOE projects while continuing to work on projects associated with management of rainbow trout fisheries in small lakes and kokanee/piscivore systems in large lakes and reservoirs.
My previous role within the BC Ministry of Environment (BCMOE) was to lead research initiatives that were relevant to high-priority environmental management issues. I worked with teams of 2-8 people made up of professors, graduate students and resource managers from government and industry. My responsibilities within the team included: writing grant proposals, reporting to granting agencies, developing methods for and performing data analysis, presenting results to research and resource management professionals, revising publication drafts by team members and managing budgets. In the 10 years prior to retirement, I supervised a research budget that averaged over $150,000/yr (excluding my salary and admin support).
My Role at UBC includes: Sitting on graduate student advisory committees, Supervision of monetary support from MOE to graduate student projects, Access to large data sets maintained by BCMOE and Presentation of research finding to student audiences. Over the last 15 years I have participated in advisory committees for 19 PhD and MSc students from UBC and SFU. In most of these, I have been involved in all phases of the research: project proposal, assisting in data collection and analysis, reviewing thesis drafts. Funding commitments, supervised by me, from BCMOE to graduate student projects in 2008 total $68,000. An example of access to BCMOE data sets is my collaborative work with Dr. R.D. Moore (UBC Geography) on the prediction of stream temperatures in BC. Recent lectures are: The Biology and Management of Rainbow Trout Sportfisheries in small BC Lakes, (CONS 486, Fish Conservation and Management), Defining Fisheries Sensitive Watersheds under the BC Forest and Range Practices Act (FRST 386 Aquatic Ecosystems and Fish in Forested Watersheds).
Projects in which I am a Principle Investigator:
Identifying temperature sensitive streams from observed clines in fish community structure and physical models of stream temperature (2006-present)
Evaluating the consequences of alternative fish entrainment mitigation strategies at existing and proposed hydro electric reservoirs (2009-present).
Quantifying the relationships between density, growth, survival, predators and food supply for rainbow trout in small lakes (1998-present).
Evaluating alternative management policies on small lakes using simulation modelling (2001-present).
Development of a strategy for classifying and preserving ecotype variation in rainbow trout (1997-2009).
Identifying watersheds that have both high fisheries value and high sensitivity to forest harvesting using GIS modeling at a provincial scale (2003-2010).
Quantifying aquatic biodiversity values using GIS modeling at a Provincial scale (2002-2011).
Quantifying habitat requirements of endangered salmonids with respect to forest harvesting activities (2007-2008)
