Examining the biological significance of thermal refugia for juvenile Atlantic salmon (Salmo salar) in a changing climate.
Atlantic salmon is an important fish species for the province of New Brunswick. New Brunswick houses the Miramichi river system which has become the most productive Atlantic salmon run in North America. Like many other estuaries, the river is highly susceptible to increasing water temperatures that surpass the lethal limit of salmonids (>23°C) throughout summer months. During such events, juvenile salmon populations abandon all territorial behaviours and aggregate near groundwater seeps and small tributaries (coldwater refugia) where they are less susceptible to high temperature stress. In order to sustain a viable population, it is important we understand the physiological and behavioural adaptations of salmonids in relation to these critical habitats. The objectives of this study are to build on existing research in order to determine if proximity to cool-water refugia affects the the survival and distribution of wild Atlantic salmon populations on both a spatial and temporal scale. The outcome of the study will be used to better inform fisheries management of the importance of protecting critical salmon habitat and these cool-water resources.
