Over the past 520 million years, the process of evolution has produced a diversity of nearly 25000 species of fish. This diversity includes thousands of different fin designs which are largely the product of natural selection for locomotor performance. Fish fins can be grouped into two major categories: median and paired fins. Fins are typically supported at their base by a series of segmentally arranged bony or cartilaginous elements, and fish have extensive muscular control over fin… Expand
Fish locomotion: kinematics and hydrodynamics of flexible foil-like fins
The fins of fishes are remarkable propulsive devices that appear at the origin of fishes about 500 million years ago and have been a key feature of fish evolutionary diversification. Most fishExpand
Fin–fin interactions during locomotion in a simplified biomimetic fish model
TLDR
This work presents a flexible fish-like robotic model that better represents the kinematics of swimming fishes while still being simple enough to examine a range of morphologies and motion patterns and creates statistical models that predict the individual effects of each kinematic and morphological variable.

Mechanics of Pectoral Fin Swimming in Fishes
TLDR
This chapter describes how deforming bodies and fins interact with the surrounding fluid to generate propulsive forces, and which measures of swimming performance are most important in influencing how fishes exploit resources in their environment. Expand
Functional morphology of the fin rays of teleost fishes
TLDR
This work examined the range of motion and curvatures of the pectoral fin rays of bluegill sunfish during steady swimming, turning maneuvers, and hovering behaviors and during a vortex perturbation impacting the fin during the fin beat, suggesting flexibility may offer intrinsic damping of environmental fluid perturbations encountered by swimming fish.

TLDR
How modifications to control surfaces can alter flow and increase hydrodynamic performance is reviewed to alter flow to increase lift, reduce drag and enhance thrust in the case of propulsive fin-based systems in fishes and marine mammals. Expand
Hydrodynamics of median-fin interactions in fish-like locomotion: Effects of fin shape and movement
Recent studies have shown that by utilizing the interactions among median fins (the dorsal, anal, and caudal fins), fishes can achieve higher propulsion performance at the caudal fin. This work aimsExpand

TLDR
An undulating fin mechanism has been developed and used as the propulsion system of fish in various fin types and the layout and workspace of the modular fin segments are considered and analyzed. Expand
Median fin function in bluegill sunfish Lepomis macrochirus: streamwise vortex structure during steady swimming

  • 2006
TLDR
This study analyzes flow in the transverse plane at a range of positions around bluegill sunfish Lepomis macrochirus, from the trailing edges of the dorsal and anal fins to the near wake, and proposes a three-dimensional structure of the vortex wake in which vortices from the caudal notch are elongated by the dorso-ventral cupping motion of the tail.

Experimental Hydrodynamics and Evolution: Function of Median Fins in Ray-finned Fishes1
TLDR
Two recent technical developments in DPIV methodology are summarized: high-resolution DPIV using a recursive local-correlation algorithm allows quantification of small vortices, while stereo-DPIV permits simultaneous measurement of x, y, and z flow velocity components within a single planar light sheet.

Function of pectoral fins in rainbow trout: behavioral repertoire and hydrodynamic forces
TLDR
Despite its traditional categorization as a propulsor of limited functional importance, the salmoniform pectoral fin exhibits a diverse locomotor repertoire comparable to that of higher teleostean fishes. Expand

TLDR
Three-dimensional kinematic analysis showed that during steady horizontal swimming the pectoral fins are oriented with a negative angle of attack predicted to generate no significant lift, and a new force balance for swimming sturgeon is proposed for steady swimming and vertical maneuvering. Expand

TLDR
It is found that the pectoral fins of sunfish generate significantly higher forces for turning and direct braking forces closer to the center of mass of the body than the pectoral fins of trout. Expand

Three-dimensional analysis of pectoral fin propulsion in the largemouth bass revealed that bass fin kinematics are much more complex than expected on a rowing model of drag-based propulsion, and that the pectora fins may produce drag- based thrust even during protraction. Expand

Locomotor function of the dorsal fin in teleost fishes: experimental analysis of wake forces in sunfish.
TLDR
Empirical evidence is presented that vortex structures generated by the soft dorsal fin upstream can constructively interact with those produced by the caudal fin downstream, and Reinforcement of circulation around the tail through interception of the dorsal fin's vortices is proposed as a mechanism for augmenting wake energy and enhancing thrust.

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.
