Species at risk

Species at risk

Have you ever wondered why some species are rare and others are common? Are you interested in understanding the population dynamics of, and threats to, Canada's endangered marine and freshwater species? Do you want to gain expertise conducting research on endangered, threatened and special concern fish, invertebrates, and marine mammals and their habitats within Canada?

Canadian freshwater ecosystems contain over 100 freshwater and marine species listed under the federal Species at Risk Act (SARA), 2002. Research conducted in species at risk science supports the assessment, protection and recovery of Canada's imperiled species, including by determining how recovery actions should be undertaken.

Canada's imperiled species are threatened due to human activities, which include:

  • habitat modification, such as:
    • alteration of flow regimes
    • dredging
    • landcover change
  • the introduction of aquatic invasive species
  • fishing mortality
  • climate change

Species at risk science at DFO aims to understand the factors influencing Canada's imperiled species, and to determine how listed species can be best protected. A core component of species at risk science is the identification of critical habitat, a legal requirement under SARA.

The 4 main research themes in species at risk science are:

  1. population ecology, which involves understanding the distribution, abundance, biotic interactions and genetics of listed species
  2. habitat-related research, which involves understanding the habitat features necessary to support different life stages
  3. threat research, such as understanding how populations respond to different environmental perturbations, and ways to mitigate these threats
  4. research to support the recovery of listed species, such as developing restoration targets

As a student researcher in species at risk science, you'll work with research technicians, biologists and scientists to measure and evaluate populations of at-risk fish, invertebrates and marine mammals in the field. You'll help us to quantify species habitat and analyze results in the laboratory and with computer-based methods.

Species at risk research at DFO can include:

  • estimating the abundance and composition of imperiled populations with tools like electrofishing, seine netting or hoop netting
  • evaluating relationships between population abundance and habitat quality to inform critical habitat designations
  • evaluating the quantity and health of critical habitat using physical and automated methods
  • quantifying threats to endangered populations, such as the role of climate variability and a range of habitat perturbations
  • conducting tagging studies to understand where, when and how populations are responding to environmental change

We're seeking motivated individuals with scientific backgrounds to help solve current research challenges in species at risk science. Apply today!

Stock Assessment

Stock assessment

Are you curious about how many fish are actually in the ocean? Stock assessment science may be right for you!

Stock assessment is critical work and the results inform DFO about:

  • the status of commercial fish stocks from one fishing season to the next
  • what are sustainable harvest levels
  • the health of the marine ecosystem

A fundamental principle of stock assessment advice is that there should be enough fish left in a stock to spawn healthy new generations for the future after fishing and deaths from natural causes.

There are 2 components to stock assessment science at DFO.

  1. Data collection: technicians and biologists go out to sea and collect data on fish populations such as numbers of juveniles, age, length, sex and breeding condition.
    • Data used in stock assessments also comes from other sources, including landings at ports and catch rates from fishers.
  2. Converting data to advice: research scientists take the fisheries data and turn it into advice.
    • They do this by taking the data and constructing mathematical and statistical models to convert the data into fish population estimates.

Your duties would vary depending on where you work in Canada. Under guided supervision, you may have opportunities to:

  • collect biological data on fish populations, including lengths, weights and otoliths at sea
  • age fish using otoliths, stomach content analysis and genetic studies in the laboratory
  • run stock assessment models, analyze data and write code in the computer laboratory

We're looking for passionate, detail-oriented, organized and resourceful students. Join our team in stock assessment science! Apply today!
