The effect of wetsuit leg coverage on swimming speed and selected physiological measures
The effect of wetsuit leg coverage on swimming speed and body temperatures was investigated by having 10 triathletes swim 1500 meters 4 times in two different water temperatures in short sleeved wetsuits. Subjects swam twice in a full wetsuit which covered the leg to the ankle and twice in a …

Use of non-lethal endpoints to establish water quality requirements and optima of the Topeka Shiner (notropis topeka)
… at different acclimation temperatures using swimming speed, and (3) determining the onset of effect of sub-lethal levels of nitrogenous compounds and chloride concentrations on swimming speed. We determined ASR50 and ASR90 (i.e. dissolved oxygen concentrations where 50 percent and 90 percent …

Swimming behavior and energetics of sharks
In a field study of blue shark swimming behavior, acoustic telemetry was used to record depth, swimming speed and tailbeat frequency from free-ranging blue sharks (Prionace glauca) in northwestern Atlantic slope waters. Records obtained from five sharks show a consistent pattern of vertical …

The Effects of Seasonal Changes and Turbidity on Swimming Performance in White Crappie Pomoxis Annularis and Black Crappie Pomoxis Nigromaculatus.
Factors that affect swimming performance in fish can also affect fitness. I tested the effects of time of day, season and turbidity on swimming performance in black crappie Pomoxis nigromaculatus and white crappie Pomoxis annularis. These closely related fish co-occur and their relative abundance …

Breeding Jackass Penguins as pelagic predators
… remote-sensing devices to measure swimming speed, distance travelled and time spent at each depth by foraging Jackass Penguins. Penguin swimming speed was reduced in proportion to the cross-sectional area of the devices, and results derived from birds wearing the devices had to be …

Dynamics of semi-flexible fibres in viscous flow
… shear flow and the effect of flexibility on the swimming speed of helical flagella are investigated. High aspect ratio particles such as carbon and glass fibres are often added as fillers to processed polymers. Although these materials have high rigidity, the large aspect ratiomakes the fibres …

Swimming in slime
… waving sheet. We consider two main cases of this swimming sheet problem. In the first case, the type of wave being propagated down the length of the swimmer is specified. We compare the swimming speeds of viscoelastic shear thinning, shear thickening and Newtonian fluids for a fixed propagating …

Behavior, Energetics, And Swimming Performance Of The American Paddlefish, Polyodon Spathula, In A Lower Mississippi River Oxbow
… respirometry to estimate metabolic rates and swimming efficiency of paddlefish within an oxbow located just north of Clarksdale, Mississippi (Moon Lake). Paddlefish overwintered in the deepest portions of Moon Lake with little movement into shallower areas. Paddlefish swimming performance was …

Simulation and theoretical study of swimming and resistive forces within granular media
… to explain the subsurface locomotion of the sand-swimming sandfish lizard. I developed a resistive force theory (RFT) with empirical force laws to explain the swimming speed observed in animal experiments. By varying the amplitude of the undulation in the RFT, I found that the range of amplitude …

Sublethal effects of cadmium and diazinon on reproduction and larval behavior in zebrafish (Brachydanio rerio)
… and diazinon on reproductive success, larval swimming behavior, and a pheromonally regulated steroid. Adult zebrafish (Brachydanio rerio) were sublethally exposed to either cadmium or diazinon and median spawning time, fecundity, fertilization success, gonadal 17a,20pdihydroxy- …

Aspects of the respiratory metabolism of juvenile rainbow trout (Oncorhynchus mykiss) at sustained swimming speeds
… of small nektonic organisms at various swimming speeds is presented. Juvenile rainbow trout (Oncorhynchus mykiss) were used to evaluate the performance of the apparatus. Twenty-four hour experiments indicated no detectable diurnal variation in the respiration rates of juvenile rainbow …

Developing High Performance Linear Carangiform Swimming
This thesis examines the linear swimming motion of Carangiform fish, and investigates how to improve the swimming performance of robotic fish within the fields of kinematic modeling and mechanical engineering, in a successful attempt to replicate the high performance of real fish. Intensive …

Experimental study of fish response to turbulent flow fields generated by in-stream structures
… of mean and turbulent flow statistics with swimming behavior. Mean velocities, turbulent intensity, Reynolds stresses, and vorticity are investigated to explore both intensity and orientation of turbulent flow structures and their impact on swimming speed, acceleration, as well as tail beat …

Transport of active particles in complex environments
… experimentally by tracking wild-type and smooth-swimming mutants of the model bacterium Escherichia coli swimming in microfluidic channels with lattices of obstacles. Based on the microscopic analysis of scattering events, the diffusive transport was modelled and compared to the experimental …

Wave energy and the role of swimming in reef fish ecology
… water motion among reef habitats with the swimming mode and performance of resident reef fishes. Encompassing ten families (Acanthuridae, Chaetodontidae, Labridae, Lutjanidae, Nemipteridae, Pomacanthidae, Pomacentridae, Serranidae, Siganidae and Zanclidae), the generality of this functional …

Comparative hypoxia responses and oxygen sensing in galaxiid fishes
… of aquatic surface respiration and an elevated swimming speed (body lengths (BL) s-1). Banded kokopu was less averse to hypoxia than inanga, as they displayed a lower hypoxia avoidance threshold and demonstrated horizontal migration from severe hypoxia (< 2.5 mg L-1). By contrast, no avoidance …

Phenotypic Consequences of Gestation Temperature in the Northern Watersnake, Nerodia Sipedon
… In snakes, offspring morphology, locomotor speed, anti-predator behavior, and growth are known to be affected by developmental temperature and are likely to have important fitness consequences. I explored the influence of gestation temperature on offspring phenotypes produced by gravid …
