The sea louse (Lepeophtheirus salmonis) is the most economically important parasite that affects salmon farming and it is a cause for major environmental concern due to the risk of transmission to wild salmon population. The development of drug resistance in a number of L. salmonis populations to the most effective sea lice therapy - SLICETM diminishes the ability to control sea lice levels on farmed salmon.
I will be working as an intern with Vynx Design Inc. generating temperature forecasts that will aid decision making for salmon fisheries managers. My research will focus on improving the accuracy and effectiveness of short-term temperature forecasts as well as enhancing the understanding of the relationship between river conditions and mortality. I will use both deterministic and statistical models to generate 10-day river temperature forecasts that will be used by Fraser River sockeye salmon in-season management for predicting in-river loss.
Wildlife viewing-based ecotourism relies on accurate accounting and predictable presence of their target animal populations. Spirit Bear Lodge, a community owned company of the Kitasoo/Xai’xais First Nation, operates a bear viewing operation throughout their Traditional Territory on the central coast of British Columbia.
In 2012, the American Eel were recommended by the Committee on the Status of Endangered Wildlife in Canada to be upgraded to Threatened from Special Concern. American Eel are important to Aboriginal people, and recreational and commercial fishers. Research from a four-year-study (2009-2012) occurring in a near pristine watershed, looked at habitat selection and population estimates of American Eel.
The Atlantic salmon is unable to regulate its body temperature, and is therefore at risk from the negative effects of climate change. During summer heatwaves when river water exceeds 23°, Atlantic salmon become thermally stressed and move into small cold water patches in order to survive. These patches are known as ‘thermal refugia’ and are thought to be significant in allowing salmon to survive increased water temperatures.
The internship seeks to develop an acoustic classification algorithm that estimates the organism composition and density of plankton. A series of experiments have been conducted using trawl nets where a four-frequency sonar device was pointed across the net openings. The catch from each trawl survey is broken down into an estimate of the relative composition of different organisms. This internship involves relating the known catch to the corresponding acoustic measurements of that catch.
