Genetic analysis reveals bidirectional fish movement across the Continental Divide via an interbasin water transfer
… water demand, but their impacts on the movement and gene flow of aquatic organisms are poorly understood. The Grand Ditch is an interbasin water transfer that diverts water from tributaries of the upper Colorado River on the west side of the Continental Divide to the upper Cache la …

Washington D.C. Aquarium: An Exploration of Shaping the Water: Building Sculpture Along the Existing Landscape
… an interactive walkway along the river. The movement of the water is redirected to stimulate the enjoyable atmospere for the people. The aquarium's shape is highly designed to reflect the fish movement. This project is a combination of advanced structure, inspiring architectural expression, …

Spatial and temporal dynamics of an exploited reef-fish population
The successful management of the fishery for galjoen Dichistius capensis depends on an understanding of its spatial and temporal dynamics. This thesis investigates the movement of galjoen and its fishery parameters, and evaluates the role of marine protected areas (MPAs) and alternative assessment …

The movement ecology of common bream Abramis brama in a highly connected wetland using acoustic telemetry.
Evidence increasingly suggests that the movement behaviours of potamodromous fishes can be highly diverse in well-connected systems. Intra-population divergence in spatial and temporal resource-use is an important component of fish distribution patterns and population structure, which can affect …

An Analysis of Juvenile Chinook Salmon Outmigration Speed and Survival in Response to Habitat Features: Sacramento River from Knights Landing to Sacramento, California
… a better understanding of their survival and movement rates during outmigration, late fall run Chinook salmon smolts were tracked using acoustic telemetry techniques. Habitat features were measured and quantified throughout the study area to evaluate how Chinook salmon respond to key levee …

Movement Ecology and Trophic Dynamics in the northern Gulf of Mexico: Implications for Fisheries Management
… supports lucrative commercial and recreational fisheries ranging from low-trophic-level species, such as penaeid shrimps and forage fishes, to high-trophic-level predators (e.g. Yellowfin Tuna). This thesis contributes to the region’s ecological knowledge, with the primary aim of enhancing …

Resource use and life history patterns of juvenile Coho and Chinook salmon in an Alaskan estuary
… I describe the resource use, residence, and movement patterns of juvenile salmon in the Anchor River estuary in southcentral Alaska. Specifically, I (1) assess the resource partitioning between juvenile Coho and Chinook salmon, (2) determine which age classes use the estuary and for how long, …

Movement of Selected Nearshore Temperate Reef Fishes Along California's Central Coast
Worldwide fisheries decline has spurred the utilization of new conservation and management approaches, including the implementation of marine reserves. The diversity of goals and expected outcomes should guide the marine reserve design process, coupled with a thorough understanding of the ecology …

Fish passage design for Southern Hemisphere small-bodied fish: Hydrodynamic and behavioural assessment using spoiler baffles
… arrangement that can potentially be used as fish passage solution for future remediation of culverts. To achieve this, at first, a framework has been established to measure and quantify fish behavioural information in a highly heterogenous turbulent flow. The required turbulent flow is …

Applied ecology and management of the invasive topmouth gudgeon Pseudorabora parva in England & Wales.
… wider environment. This research used the Asian fish of the Cyprinidae family, topmouth gudgeon Pseudorasbora parva, as the model species, a highly invasive fish in mainland Europe. England and Wales was the model area, where 26 P. parva populations have been recorded but the species is not yet …

Structure, Dynamics, and Movement Patterns for Crappies in South Dakota Waters
… telemetry was used to determine monthly and diel movements of white crappies Pomoxis annularis in a South Dakota glacial lake. Sonic transmitters were surgically implanted in 37 adult white crappies (265-327 mm, total length; 315-530g). From 15 April to 15 October, 1, 712 locations were recorded …

Brook Trout Population Genetic Tools for Natural Barriers in Fragmented Subwatersheds
Barriers to fish movement can cause aquatic habitat fragmentation by reducing the amount of available habitat. The primary goal of my research was to investigate applications of population genetic analysis tools as indicators of barrier effects on brook trout populations in fragmented …

The physiological effects of elevated carbon dioxide, in the context of non-physical fish barriers, on unionid mussels
… (climate change and more recently non-physical fish barriers) sources. Carbon dioxide has proven very effective at causing avoidance and deterring fish movement. This is promising for its use as a non-physical barrier; however, before these barriers can be implemented, the impacts of elevated …

Distribution, Movement, and Ecology of Etheostoma spilotum (Gilbert), the Kentucky Arrow Darter, in Gilberts Big Creek and Elisha Creek, Red Bird River Basin, Clay and Leslie Counties, Kentucky
… study was designed to investigate the species’ movement capabilities, population dynamics, and overall ecology in two streams (Gilberts Big and Elisha Creek) in the Red Bird Ranger District, Daniel Boone National Forest, Kentucky. Project objectives included quantification of movement patterns, …

The Contribution of Missouri River Reservoir Side-Channel and Floodplain Habitats to Mainstem Fish Populations: The Effects of Losing Connectivity Between Hipple Lake and Lake Sharpe
… thought to be crucial habitat for prey and sport fish. Hipple Lake, the only warm-water floodplain embayment in Lake Sharpe, is in danger of losing connectivity to the reservoir because of sedimentation resulting from the 2011 flood. To evaluate Hipple Lake’s natal and adult contribution to Lake …

Chapter 1, a dichotomous key for the identification of nine salmonids of the Inland Northwest using six diagnostic skull bones; and associated equations to estimate total length and weight form bones ingested by piscivores or found in archeological sites; Chapter 2, Utilization of acoustic biotelemetry to define the movements of Lake Roosevelt Redband trout, oncorhynchus mykiss gairdneri
"The fish skull is a complex anatomical structure, comprised of numerous bones that are often unique to the fish's genera or species. These unique qualities allow researchers to use bone to identify and quantify fish in piscivore and archeological investigations. Due to the high degree of …

Using instream stationary antennas to monitor the movements of warm water fishes in a reach of stream bisected by a culvert
… the differences in the non-migratory movement patterns of six fish species in a 280m reach of stream bisected by a culvert (impeded), and a 300m reach of stream with no movement barriers (unimpeded). This study took place between July 1, 2018 and November 14, 2018 in Raccoon Creek, …
