TLDR
In this paper, the authors discuss the perfect fluid forces involved in fish propulsion in the case of low aspect ratio and show that a travelling wave with linearly increasing ampli-tude is imposed on a rigid strip of finite width oscillating about the forward end.Abstract:
This paper is a discussion of perfect fluid forces involved in fish propulsion. First, the two-dimensional problem is solved in elliptic cylinder co-ordinates in which the surface, or strip μ = 0 is used to approximate a ‘fish’. A travelling wave with linearly increasing amplitude is imposed on the strip to represent the motion of the fish. The problem then is investigated for a rigid strip of finite width oscillating about the forward end. Results of this calculation are used to correct the general force expression to the case of low aspect ratio. Experimental results are then discussed which verify the validity of the calculations.read more

Review of fish swimming modes for aquatic locomotion
TL;DR: In this article, an overview of the swimming mechanisms employed by fish is presented, with a relevant and useful introduction to the existing literature for engineers with an interest in the emerging area of aquatic biomechanisms.

1 - Form, Function, and Locomotory Habits in Fish
TL;DR: Some fish are capable of brief aerial locomotion by passive gliding rather than by flying (and swim underwater by conventional body undulations), comparable to those restricted groups of mammals, amphibians, and reptiles that can glide but are not primarily adapted to this mode of locomotion.

Aerohydrodynamics of flapping-wing propulsors
TL;DR: The physical and the design factors are discussed, which affect the aerohydrodynamic characteristics of flapping wings and that therefore have to be accounted for in the modern mathematical models.

Hydromechanics of Swimming of Fishes and Cetaceans
TL;DR: In this paper, the undulatory motions that most aquatic animals make to propel themselves through water may be divided into two components: one perpendicular and the other tangential to the animal's instantaneous longitudinal axis of centroid.

On ostraciiform locomotion
TL;DR: In contrast, very little work has been done on the ostraciiform mode of locomotion as mentioned in this paper, which has not yet been analyzed in living fish, as Gray (1968) points out.
