Relations of Geomorphology to Stream Habitat and Trout Standing Stock in Small Rocky Mountain Streams
متن کامل
Empirical relationships between body tissue composition and bioelectrical impedance of brook trout Salvelinus fontinalis from a Rocky Mountain Stream.
Bioelectrical impedance analysis (BIA) analysis was carried out in the field on anaesthetized Salvelinus fontinalis electrofished from a mountain stream in Alberta, Canada; the fish were then sacrificed for subsequent analysis of tissue composition. Water content was assessed by comparing wet and dry mass, and total body lipid content was measured by Soxhlet extraction with petroleum ether. A m...
متن کاملMechanisms Limiting a Vertebrate Invasion: Brook Trout in Mountain Streams
I used multiple approaches to study brook trout invasions in mountainous streams of Idaho and Montana, USA. After studying marked fish in experimental reaches and fish distributions throughout a drainage, I concluded that larger brook trout (95mm) moved more than smaller ones and were probably responsible for most dispersal leading to invasion. Contrary to earlier hypotheses, poor swimming abil...
متن کاملHydraulic Complexity Metrics for Evaluating In-Stream Brook Trout Habitat
A two-dimensional hydraulic model River2D was used to investigate the significance of flow complexity on habitat preferences of brook trout Salvelinus fontinalis) in the high-gradient Staunton River in Shenandoah National Park, Virginia. Two 100-m reaches were modeled where detailed brook trout surveys 10–30-m resolution have been conducted annually since 1997. Spatial hydraulic complexity metr...
متن کاملHow High Can Brook Trout Jump? A Laboratory Evaluation of Brook Trout Jumping Performance
—Quantitative data on how high brook trout Salvelinus fontinalis can jump are crucial for efforts by fisheries managers to exclude brook trout from streams containing native cutthroat trout Oncorhynchus clarkii subspp. and to build effective fishways for brook trout migration. We identified factors that could influence brook trout jumping ability and demonstrated how this knowledge could be app...
