Abstract Digital videography was used to study the swimming performance of the adult fish Galaxias maculatus in a flume at fixed flows. Instantaneous fish swimming velocities varied about the mean flume velocity and these variations in swimming speed were found to increase as velocity in the flume increased. Standard deviations in swimming velocity measured in the longitudinal direction increased from SD 0.183 m s–1 at U0 = 0.40 m s–1, SD 0.191 at U0 = 0.48 m s–1 to SD 0.237 m s–1 at U0 = 0.60… 
Hydrodynamics of linear acceleration in bluegill sunfish, Lepomis macrochirus
Bluegill sunfish accelerate primarily by increasing the total amount of force produced in each tail beat but not by substantially redirecting forces, appearing to face a trade-off during acceleration.
Changes to flow and turbulence caused by different concentrations of fish in a circular tank
ABSTRACT The effects of juvenile Atlantic salmon (Salmo salar) on flow and turbulence in a circular tank were investigated. Three fish sizes were studied (37.5 g, 82.5 g and 218 g) with between
Field swimming performance of bluegill sunfish, Lepomis macrochirus: implications for field activity cost estimates and laboratory measures of swimming performance
3‐D underwater videography is used to quantify the swimming trajectories and propulsive modes of bluegills sunfish in the field with high spatial and temporal resolution, suggesting that speed and path curvature data could be used to derive reasonable estimates of locomotor cost that fit within measured capacities for sustainable activity.
Facilitation of upstream passage for juveniles of a weakly swimming migratory galaxiid
To facilitate fish passage at barriers for weakly swimming fish species like juvenile īnanga, ramps should provide a rough surface substrate and have an optimal angle of 5° for a 3-m ramp.
Field swimming behavior in largemouth bass deviates from predictions based on economy and propulsive efficiency
Video analysis of largemouth bass swimming behavior in the field suggests that they do not use swimming speeds or propulsive movements that maximize economy and efficiency.
Hydrodynamics of linear acceleration in bluegill sunfish Lepomis macrochirus
It is found that bluegill produce vortices with higher circulation during acceleration, indicating a higher force per tail beat, but do not substantially redirect the force.
On upstream fish passage in standard box culverts: interactions between fish and turbulence
ABSTRACT The challenge to understanding the fluid mechanics of fish swimming is knowing exactly what the water is doing where the fish swims. Recent field and laboratory observations in box culvert
The fish Strouhal number as a criterion for hydraulic fishway design
Abstract Longitudinal river fragmentation through physical barriers is a major issue for the conservation of aquatic species in regions with intense hydropower development, such as Chile. The
Rethinking swimming performance tests for bottom-dwelling fish: the case of European glass eel (Anguilla anguilla)
Results showed that burst-and-coast swimming mode was increasingly adopted by glass eel, especially when U was higher than 0.3 ms-1.77, and a general formula to link near-bottom velocity, water temperature and active swimming time can be useful in ecological engineering applications.


Swimming performances of some native freshwater fishes
Field observations of Mugil cephalus corresponded with limited flume data, suggesting this species is a less vigorous swimmer: water velocities below 0.15 m s‐1 would allow its passage over obstacles less than 5 m in length whereas longer obstacles, without resting areas of static water, may requ...
The effect of turbulence on the cost of swimming for juvenile Atlantic salmon (Salmo salar)
Fish activity costs are often estimated by transforming their swimming speed in energy expenditures with respirometry models developed while forcing fish to swim against a flow of constant velocity.
The relationship between swimming speed and respiration rate for larvae and juveniles of two cyprinid species, Chalcalburnus chalcoides and Rutilus rutilus, was measured in a flow-tunnel at 20°C to discuss the changing swimming pattern during ontogeny, the shift from cutaneous to branchial respiration and the metabolic processes involved.
Influence of body weight, swimming characteristics, and water temperature on the cost of swimming in brook trout (Salvelinus fontinalis)
It is confirmed, with a wider range of experimental data, that spontaneous swimming costs of fish are 3- to 22-fold (8-fold average difference) more energy demanding than predicted by forced swimming models developed using fish swimming at constant speeds and directions in flumes.
Burst‐Swimming Performance of Larval Zebra Danios and the Effects of Diel Temperature Fluctuations
Results suggest that, other factors being equal, larvae are potentially more vulnerable to predation at sun... and a predictive model relating St to temperature was developed.
Escape manoeuvres in the spiny dogfish (Squalus acanthias)
The locomotor performance observed in dogfish is consistent with their morphological characteristics: (1) low locomotorperformance associated with low thrust developed by their relatively small posterior depth of section and (2) relatively high manoeuvrability associated with their high flexibility.
Shifts in drag and swimming potential during grayling ontogenesis: relations with habitat use
The concept of hydrodynamic potential (i.e. hydrodynamics of shape and swimming capacities) could be a useful tool in fish ecomorphology and predictions of habitat use.

Chub entrained in larger numbers and for longer over a wider range of current speeds and temperatures than bass, and the periodicity of body perturbations decreased and the amplitude increased with current speed, but the variability was high and differences were not significant.
Effects of fish size, time‐to‐fatigue and turbulence on swimming performance: a case study of Galaxias maculatus
The data suggest that future studies of turbulence effects on fish behaviour should involve, in addition to turbulence energetics, consideration of fish dimensions in relation to the spectrum of turbulence scales.
In‐stream habitat suitability criteria for feeding inanga (Galaxias maculatus)
Abstract Inanga (Galaxias maculatus Jenyns) are the basis of an important recreational and commercial freshwater fishery that has declined over the past 100 years, probably because of habitat
