Abstract:
We compared morphometry and total swimming costs of wild, farmed (first-generation hatchery progeny of wild progenitors) and domesticated (seventh-generation progeny of the Norwegian aquaculture strain) juvenile Atlantic salmon (Salmo salar). Respirometry experiments were performed to assess total swimming costs of fish ranging in size from 4.0 to 16.1 g wet mass at a water temperature of 15 °C. Fish were subjected to flow conditions of low and high turbulence. Total swimming costs increased significantly with intensity of turbulence and were, on average, 1.4 times higher at high than at low t

Abstract:
Individual computations and social interactions underlying collective behavior in groups of animals are of great ethological, behavioral, and theoretical interest. While complex individual behaviors have successfully been parsed into small dictionaries of stereotyped behavioral modes, studies of collective behavior largely ignored these findings; instead, their focus was on inferring single, mode-independent social interaction rules that reproduced macroscopic and often qualitative features of group behavior. Here, we bring these two approaches together to predict individual swimming patterns

In situ swimming speed and swimming behaviour of dielly migrating planktivorous fish were studied at a 120-m-deep location. Acoustic target tracking was performed using a hull-mounted transducer and submersible transducers located on the sea bottom and free hanging in the water column. The original data displayed a relationship between distance to transducer and swimming speed. A simplistic smoother applied during post-processing, appeared to break this relationship. Target tracking thus provided robust results on in situ swimming behaviour throughout the water column. Swimming speeds of deep-

Seabass swimming behavior was investigated in a salt-marsh area located along the Atlantic coast north of La Rochelle, France.

Swimming activity of single fish and fish in a group was studied using an acoustic telemetry recording system. This study demonstrates that swimming activity levels and patterns of this species are modified by a group effect.

Wild-type and long-finned differ in total length (TL), fork length (FL), caudal fin length (CFL) and caudal fin height (CFH). No-tail has no caudal fin and is significantly smaller in standard length (SL) than the other types. Critical swimming speeds (U(crit)) were measured at 28 degrees C

Abstract:
Undulatory swimming in fish is powered by the segmental body musculature of the myotomes. Power generated by this muscle and the interactions between the fish and the water generate a backward-travelling wave of lateral displacement of the body and caudal fin. The body and tail push against the water, generating forward thrust. The muscle activation and strain patterns that underlie body bending and thrust generation have been described for a number of species and show considerable variation. This suggests that muscle function may also vary among species. This variation must be due in large pa

Abstract The reaction behaviour of juvenile Japanese flounder (Paralichthys olivaceus) to towed grids (0.5 × 0.2 m, horizontally, or vertically orientated bars at 10-mm intervals) was observed as a means of understanding fish behaviour in relation to grid selection for a beam trawl fishery in Tokyo Bay. Reaction behaviours were categorized within four patterns by grid types and illumination levels: (i) forward swimming in towed direction; (ii) swimming over the grid; (iii) sticking on the grid; and (iv) passing through the grid. The most dominant reaction pattern was forward swimming, but its

Abstract:
We tested the ability of a stereo-video method to provide estimates of the metabolic costs of spontaneous swimming by simultaneously video taping free-swimming fish and measuring their oxygen consumption. Three swimming characteristics (speed, turning rate, and acceleration) obtained from image analysis of video recordings explained, on average, 80% of the variability in spontaneous swimming costs. Colinearity among the swimming characteristics prevented us from estimating their relative importance. We converted the swimming speeds recorded by the stereo-video system to metabolic costs using r

Abstract:
I evaluated the precision and accuracy of the stereocinematographic (SCG) method for estimating fish swimming speed. The SCG method implements the differences in images recorded by two cameras to determine the position of a target in an x, y, z, coordinate system. Movements and speeds were determined using variations in the position of the targets over time. Movements of rulers [Formula: see text] estimated in the laboratory did not differ significantly from measured values. The accuracy of the SCG method in the field was assessed by comparing simultaneous estimates of the speed of the head an

Rhythmicity in swimming activity was examined by videorecording fish behaviours for 48 h.

Numerical simulations and empirical measurements of swimming Atlantic salmon (Salmo salar) were used to describe the effects of fish behavior on side-aspect target strength (TS). Simulation results were based on the numerical solution of the Helmholtz equation with the finite element method (FEM). A three-dimensional geometric model approximated the shape of the swimbladder of an Atlantic salmon. Numerical simulations were used to study the dependence of TS on the fish length, orientation, and swimming behavior. The results showed strong variation in TS, both when the side-aspect angle was cha

The gillnet selectivities for a lacustrine population of allopatric brown trout (Salmo trutta) were estimated directly, using maximum girth as the parameter for fish size. A model for capture probabilities separating the processes of encountering the net and being retained in case of an encounter was developed. Swimming distances and retention probabilities were estimated from the model. Size selectivities decreased with increasing mesh size and fish size. This was explained by decreasing swimming distances with increasing fish size. The retention probabilities are consistent with a geometrica

We propose a pose estimation method using a National Advisory Committee for Aeronautics (NACA) airfoil model for fish schools. This method allows one to understand the state in which fish are swimming based on their posture and dynamic variations. Moreover, their collective behavior can be understood based on their posture changes. Therefore, fish pose is a crucial indicator for collective behavior analysis. We use the NACA model to represent the fish posture; this enables more accurate tracking and movement prediction owing to the capability of the model in describing posture dynamics. To fit

To address this gap, young-adult mahi-mahi (Coryphaena hippurus; 25–35 cm fork length) were tagged with miniature PSATs and assessed in a two-part experiment utilizing swim tunnel respirometry and behavioral analysis of free-swimming individuals.

The critical swimming performance (Ucrit) of fish has typically been measured on individuals given a step-based test that ends in fatigue. Many of the fish given this test naturally travel in schools; a concern is that the Ucrit test underestimates the natural performance of schooling fish, as there are hydrodynamic benefits to schooling. We addressed whether Ucrit was improved by schooling by giving zebrafish (Danio rerio) Ucrit tests individually or in groups of three, five, or ten. We found that fish swam faster in schools and that schools grew more cohesive as flow speed increased. The inc

SUMMARY Among the tremendous diversity of fish, there are a small number that are considered elite in their swimming performance. These include representatives from the tunas, billfish and sharks. In addition to being elite swimmers,these fish share numerous specialized anatomical features including the structure of their swimming muscles and some form of regional endothermy,termed heterothermy. These heterothermies fall into two classes: those that maintain elevated temperatures in swimming muscles and those that have muscle-derived tissues specialized for delivering warm blood to the brain.

Passage success was high (91%) over all test velocities, as was the maximum instantaneous burst velocity (219 cm·s−1)
