How 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...
متن کاملMussel Spat Ropes Assist Redfin Bully Gobiomorphus huttoni Passage through Experimental Culverts with Velocity Barriers
The application of mussel spat rope for enabling the passage of redfin bully Gobiomorphus huttoni through culverts, which create velocity barriers, was trialled in the laboratory. No fish were able to access the un-roped control pipes whereas 52% successfully negotiated the pipes in the rope treatments. The success of fish ascending treatment pipes suggests mussel spat rope may be effective for...
متن کاملObservations on the Etiology of Goitre in Brook Trout
The arrangement and number of the ponds and troughs, the water supply, the strain of brook trout, and their distribution in the ponds and troughs according to age, have remained unchanged since our first observations in 19o9. The crowding has gradually increased during these years, but the general external appearance of cleanliness of the ponds and troughs has not changed. Those containing the ...
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 کاملEffects of Stocking on Genetics of Wild Brook Trout Populations
The study was undertaken to evaluate the long-term genetic impact of maintenance stocking upon wild brook trout (Salvelinusfontinalis) populations in Wisconsin. Trout were collected from streams of the Wolf and Fox River drainages and from the Osceola State Trout Hatchery. The stocking histories of the streams ranged from unstocked to heavily stocked for many years. The planted fish consisted p...
