What the facility does

Research on population dynamics

Area(s) of Expertise

A solid understanding of the ecology and evolution of population fluctuations is fundamental to many issues of sustainability, including human and wildlife health, food security, and resource management. We conduct analyses on the population ecology of commercially and socially important marine fish species, such as Pacific salmon and herring, to better understand their basic biology as well as sustainable harvests. We also conduct analyses of marine mammals, such as killer whales and sea lions, to better understand threats to these endangered species and to help inform their conservation management. Although infectious diseases may appear very different in fish or whales, the fundamental concepts of population ecology also applies to the emergence, persistence, and spread of infectious diseases. We analyze the dynamics of environmentally transmitted diseases to better understand the population health implications, particularly in relation to climate change, as well as transmission between domesticated and wild fish populations, such as salmon. Our analytical approaches involve a combination of mathematical modeling, statistical analysis of long-term datasets, laboratory experiments to test and refine models, and marine biology fieldwork to contribute to long-term datasets on juvenile salmon ecology and epidemiology.

Research Services

We conduct mathematical and statistical analysis of population dynamics, including time series analysis of fisheries and disease datasets. We also conduct marine biology fieldwork in the northern Vancouver Island area to generate data on disease transmission between wild and farmed salmon.

Name of equipment in use

Description of function

Fisheries Research Vessels

Two boats: (1) a 39’ former commercial fishing boat (troller) refitted to support multi-day expeditions for marine biology and fisheries research in coastal BC; (2) an 18’ workboat for conducting day trips to collect fisheries and oceanography samples. Associated equipment includes a pickup truck, fishing nets, sampling equipment, and safety equipment.

Laboratory Microcosms

Benchware needed to conduct experimental epidemiology and population dynamics using Daphnia (host) and microsporidians (parasites) including a large assemblage of glassware and aquaria, dissecting and phase-contrast microscopes, and an automated plankton counter.

Computation

A multi-processor computer to support parallel computing for fitting and analyzing models.

Experimental Stream System

A system of 6-8 experimental streams to be set up at Koffler Scientific Reserve for experimental studies of freshwater fish and stream communities.
