By Turner Sasina Brook Trout (Salvelinus fontinalis) Stenotherm Dark base coloration , scattered small red spots, with red pectoral, pelvis and anal fins, vermications Brook Trout Native Range Habitat Prefer clear cold water bodies that are often associated with mountain streams Physiological Effects of Warmer Temperature Exotherms, meaning temperature effects many aspects of a fish’s functions. Functions including growth, respiration, reproduction etc… Temperature Tolerances Physiological Habitat Loss Range from roughly 20 to 40% from climate change alone. Habitat Loss Invasive Species Stenotherms vs. Eurytherms Brown Trout and Rainbow Trout and other piscivorous fish species Invasive species are stocked for sport fishing activities Brook Trout are considered invasive Invasive Species Current Management Some management to reclaim habitat lost from land changes in the water sheds Means include replanting riparian zones, introducing Brook Trout back to viable habitats that were lost Decrease habitat fragmentation Management for Climate Change A more active approach Facilitating migration Management Future for Brook Trout Will more than likely require more active approaches to preserve the species in the uncertain future of climate change Reduce the stocking of non native species More research into methods of management in regard to climate change and surveys of watersheds.
