Movement and survival of chinook salmon fry stocked in a stream with natural barriers to anadromous fish migration
… rearing habitat, but was devoid of anadromous fish upstream of the barrier falls near tidewater. Approximately 50,000 and 260,000 chinook fry were stocked into Indian River in 1986 and 1988, respectively. The stream was divided into reaches which were stocked with equal numbers of fry. In 1988, …

The Relative Contribution of Hudson River Tributaries to River Herring Spawning Dynamics
… relative tributary contribution to anadromous fish spawning dynamics is irrefutably important when prioritizing habitat enhancement, restoration and management decisions (Everly and Boreman, 1999). Collecting sound baseline data becomes critical when seeking out the most significant …

Functional connectivity of coral reef fishes in a tropical seascape assessed by compound-specific stable isotope analyses
… pressure from human activities. Many coral reef fish species are thought to use mangroves and seagrass beds as juvenile nurseries before migrating to coral reefs as adults. Identifying essential habitats and preserving functional linkages among these habitats is likely necessary to promote …

Hydraulic and biological aspects of fish passes for dams
… the efficiency and operation of various types of fish passes for dams. This is achieved through a novel experiment of testing juvenile salmon in a scale model fish-passes with a range of small structures including vertical slots, orifices, weirs and combinations of all three. Direct comparisons of …

Mathematical and Computational modelling of soft and active matter
… such as flights of birds, swimming of school of fish, migration of bacteria and movement of herds across long distances is a fascinating phenomenon that has intrigued man for centuries. Long and details observations have resulted in numerous abstract hypothesis and theories regarding the …

The Effects of a Reservoir on Genetic Isolation in Two Species of Darters
… erosion, thermal) to the river as well as to the fish assemblages of that river. Although there have been many studies documenting the changes that occur to the fish assemblages in the impounded river, there have been fewer studies examining the effects of a reservoir on the fish inhabiting the …

Relative Abundance, Distribution, and Life Histories of Fish Species in the Colville River Watershed, Stevens County, Washington
<p>This was the first study to report on the fish assemblage of the Colville River watershed, Stevens County, Washington. Sixty-nine sites were sampled from May – November of 2013, 19 in the Colville River and 50 in its tributaries: Blue Creek (n=2), Chewelah Creek (n=6), Cottonwood Creek (n=2), …

Spatial and Temporal Patterns of Anadromous Fish Passage at Boshers Dam Vertical Slot Fishway on the James River, Richmond, Virginia
Boshers dam vertical slot fishway, James River, Virginia, U.S.A., opened in 1999 and restored connectivity to 543.3 km of spawning habitat for anadromous fish. The fishway also allowed local movement of resident species. Video observation from 2001-2005 was used to evaluate environmental predictors …
