The hydrodynamics of eel swimming
TLDR
The hydrodynamics of American eels swimming steadily at 1.4 L s-1 are examined and it is inferred that the lack of downstream flow results from a spatial and temporal balance of momentum removal and thrust generated along the body, due to the relatively uniform shape of eels.
The Kármán gait: novel body kinematics of rainbow trout swimming in a vortex street
TLDR
Interestingly, trout swimming in front of a cylinder display lower tail-beat amplitudes and body wave speeds than trout subjected to any of the other treatments, implying that the bow wake may be the most energetically favorable region for a fish to hold station near a cylinder.

The comparative functional anatomy of feeding in Polypterus senegalus, Lepisosteus oculatus, and Amia calva, three primitive actinopterygian fishes, was studied by high‐speed cinematography (200
Fish Exploiting Vortices Decrease Muscle Activity
TLDR
Quantitative flow visualization and electromyography is used to show that trout will adopt a novel mode of locomotion to slalom in between experimentally generated vortices by activating only their anterior axial muscles.
Hydrodynamics of caudal fin locomotion by chub mackerel, Scomber japonicus (Scombridae).
TLDR
The first quantitative flow visualization of the wake of a scombrid fish, chub mackerel Scomber japonicus, swimming steadily in a recirculating flow tank at cruising speeds of 1.2 and 2.2FL s(-1 is presented.
The Suction Feeding Mechanism in Sunfishes (Lepomis): An Experimental Analysis
TLDR
Data indicate that the buccal and opercular cavities are functionally separated by a gill curtain of high resistance, that inertial effects of water are important in the description of the suction feeding process, that a reverse flow of water may occur during the early phase of mouth opening prior to establishment of a buCCal to opercular flow regime, and current models of respiratory pressure and flow pattern cannot be applied to feeding.
Function of the Caudal Fin During Locomotion in Fishes: Kinematics, Flow Visualization, and Evolutionary Patterns1
TLDR
Two experimental approaches are reviewed which promise to provide new insights into the function and evolution of the caudal fin: three-dimensional kinematic analysis, and quantitative flow measurements in the wake of freely-swimming fishes using digital particle image velocimetry (DPIV).
A hydrodynamic analysis of fish swimming speed: wake structure and locomotor force in slow and fast labriform swimmers.
TLDR
Two hypotheses relating locomotor stability, maneuverability and the structure of the vortex wake are presented and a potential hydrodynamic trade-off between speed and maneuverability that arises as a geometric consequence of the orientation of vortex rings shed by the pectoral fins is proposed.
