The effect of flow turbulence on the swimming speed was studied in perch (Perca fluviatilis) with different body length. The critical flow rate was used as an index of fish swimming performance. The longer was the fish, the higher turbulence was required to decrease the critical flow rate. The mechanism of turbulence impact on fish locomotion relied on the vortex structure of the flow. The torque produced by hydrodynamic forces in a vortex favors fish overturn and loss of balance. Such effect… 
Effect of vertical slit turbulence on metabolism and swimming behavior of juvenile grass carp (ctenopharyngodon idella)
TLDR
This study of fish swimming in turbulent flow extends knowledge of fish ecology and provides data for guiding the design of hydrokinetic turbulent where needed, so preventing ecological impacts.
Modification of vertical slot fishway flow with a supplementary cylinder
ABSTRACT The paper reports on the experimental results of a vertical slot fishway (VSF) study. Particle image velocimetry and Acoustic Doppler Velocimetry were used to estimate the effects of a
Fish swimming kinematics in a turbulent wake: to spill or not to spill?
Due to the complex nature of fish-environment interactions, the effects of altered flow conditions on fish habitats and behaviour, particularly near obstructions, are not yet fully understood. Many
VARIATION OF BURST SPEED OF ZACCO PLATYPUS WITH CHANGING BODY LENGTH AND FLOW VELOCITY
The burst speed is the highest swimming speed of fish. Fish can migrate through fishways, when the maximum velocity in fishways is smaller than the burst speed. Therefore it is necessary to
The effects of hydrodynamics on the three-dimensional downstream migratory movement of Atlantic salmon.
TLDR
3D Computational fluid dynamics modelling with 2D and 3D fish positioning is combined to investigate the relation between hydrodynamics and the downstream movement of Atlantic salmon smolts and shows that fish use fine-scale flow velocity and turbulence as navigation cues offine-scale movement behaviour.
Assessing possible effects of fish-culture systems on fish swimming: the role of stability in turbulent flows
TLDR
The design of culture facilities is expected to affect levels of turbulence and may be engineered to provide optimal levels facilitating high growth.
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
Temperature surpasses the effects of velocity and turbulence on swimming performance of two invasive non-native fish species
TLDR
It is suggested that invasive species can benefit from the raised temperatures predicted under climate change forecasts by improving swimming performance in flowing water potentially facilitating their further dispersal and subsequent establishment in lotic environments.
Influence of Hydraulic Factor of Vertical-Slot Fishway on Swimming Ability of Fish
Vertical-slot fishway is widely used in different shape of fish-way due to the adaptability to water level amplitude, the hydraulic characteristics of the vertical-slot fish-way of different scale
Turbulence: does vorticity affect the structure and shape of body and fin propulsors?
TLDR
This work suggests that the archetypal streamlined "fish" shape reduces destabilizing forces for fishes swimming into eddies, and mechanisms may be found in varying the length of the propulsive wave, stiffening propulsive surfaces, and shifting to using median and paired fins when swimming at low speeds.

The Role of Microscale Turbulence in the Feeding Ecology of Larval Fish
TLDR
The chapter reviews the development and application of the term “turbulence theory” specifically as it relates to the feeding ecology of larval fish and reviews both empirical and field studies designed to test various elements of the turbulence theory.
Quantifying the contribution of small-scale turbulence to the encounter rates between larval fish and their zooplankton prey: effects of wind and tide
TLDR
It is concluded that turbulence, in addition to light and nutrients, may be an important component of the observed increase in plankton production rates and biomass at tidal fronts and at other upwelling systems.
Evidence for a dome-shaped relationship between turbulence and larval fish ingestion rates
TLDR
An analytical model is developed that shows the overall probability of feeding is a dome-shaped function of turbulent velocity and that the height and location of the maxima depend on turbulence level and the behavioral characteristics of predator and prey.
Encounter rates and swimming behavior of pause‐travel and cruise larval fish predators in calm and turbulent laboratory environments
TLDR
In terms of prey encounter rate, cod larvae benefit more from turbulent motion than do herring larvae, however, aspects of larval behavior other than prey search strategy need to be examined experimentally before the overall effects of turbulence on larval fish feeding rates can be fully evaluated.
The effects of small-scale turbulence on the ingestion rate of fathead minnow (Pimephales promelas) larvae
TLDR
The effects of turbulence on feeding by fathead minnow (Pimephales promelas) larvae are investigated to test the null hypothesis of no effect of turbulenceon ingestion, and a significant nonlinear response of ingestion to increasing turbulence is suggested.

TLDR
It was concluded that the mechanism of the rheotropic response was primarily visual, although it could also be produced by tactile clues, and there was no evidence that larvae could respond to the velocity gradients at the tank wall.
