...Emma S. Porter; A. Kurt Gamperl ABSTRACT We investigated how acclimation to 8, 4 and 1°C, and acute cooling from 8 to 1°C, affected the Atlantic salmon's aerobic and anaerobic metabolism, and cardiac function, during a critical swim speed ( U crit ) test. This study revealed several interesting...

... to evade predation and aggression via rapid swimming movements. With environmental change expected to affect the physiology and biomechanics of aquatic ectotherms, there is a growing interest in understanding how environmental stressors affect the swimming performance and behaviour of fishes during escape...

...Vincent Stin; Ramiro Godoy-Diana; Xavier Bonnet; Anthony Herrel ABSTRACT We describe a method for measuring the 3D vortical structures produced by an anguilliform swimmer using volumetric velocimetry. The wake of freely swimming dice snakes ( Natrix tessellata ) was quantified, revealing...

... for swimming (CTS max ) while exercising aerobically until fatigue and the critical thermal maximum (CT max ) under static conditions until loss of equilibrium (LOE). In the CTS max protocol, warming caused a profound increase in the rate of oxygen uptake ( Ṁ O 2 ), culminating in a gait transition from steady...

...Yordano E. Jimenez; Kelsey N. Lucas; John H. Long, Jr; Eric D. Tytell ABSTRACT Nearly all fish have flexible bodies that bend as a result of internal muscular forces and external fluid forces that are dynamically coupled with the mechanical properties of the body. Swimming is therefore strongly...

...Abigail M. Downs; Allison Kolpas; Barbara A. Block; Frank E. Fish ABSTRACT Tuna are known for exceptional swimming speeds, which are possible because of their thunniform lift-based propulsion, large muscle mass and rigid fusiform body. A rigid body should restrict maneuverability with regard...

...Takashi Hara; Shuya Hasegawa; Yasushi Iwatani; Atsuo S. Nishino ABSTRACT Swimming locomotion in aquatic vertebrates, such as fish and tadpoles, is expressed through neuron networks in the spinal cord. These networks are arranged in parallel, ubiquitously distributed and mutually coupled along...

... and bones should be analysed for power production in feeding (or at least as a compromise between swimming and feeding), and cranial muscles and bones should be analysed for their role in transmitting axial power and coordinating buccal expansion. This new framework is already yielding novel insights...

... understand how body size affects maneuverability at the largest scale, we used bio-logging data, aerial photogrammetry and a high-throughput approach to quantify the maneuvering performance of seven species of free-swimming baleen whale. We found that as body size increases, absolute maneuvering performance...

... ( Tursiops truncatus ). We measured resting metabolic rate (RMR); mean individual RMR was 0.71–1.42 times that of a similarly sized terrestrial mammal and agreed with past measurements that used breath-by-breath and flow-through respirometry. We also measured energy expenditure during submerged swim trials...

... dive, and while swimming ∼90 m horizontally underwater. Metabolic rates during stationary dives (3.82±0.56 l O 2 min −1 ) were lower than those measured at the water surface (4.64±1.04 l O 2 min −1 ), which did not differ from rates measured during subsurface swimming (4.91±0.77 l O 2 min −1 ). Thus...

... set the tolerance to 1% in cases where an electrode pair had standard deviations less than 1%, as we consider differences less than 1% to be negligible. For swimming, a trial was counted as asymmetrical only if ipsilateral activity, the side with active muscle shortening, was greater than...

... for these warm-water species. To examine this, we used open-flow respirometry to measure the energy expended during resting and swimming in both species. We found that the average resting metabolic rates (RMRs) for both the adult monk seal (753.8±26.1 kJ h −1 , mean±s.e.m.) and manatees (887.7±19.5 kJ h −1...

.... Costa et al. (2013) found that cunner ( Tautogolabrus adspersus ), which undergo winter dormancy, experienced a decrease in routine metabolic rate which equated to Q 10 =10.4 when temperature was dropped from 5 to 0°C. Additionally, swimming performance can be affected by decreasing temperatures...

Lauder ABSTRACT Whereas many fishes swim steadily, zebrafish regularly exhibit unsteady burst-and-coast swimming, which is characterized by repeated sequences of turns followed by gliding periods. Such a behavior offers the opportunity to investigate the hypothesis...

Rapidly developing approaches for studying the kinematics of swimming motion both in the lab and within the natural environment provide new avenues for research on these critical...

Farrell ABSTRACT As fish approach fatigue at high water velocities in a critical swimming speed ( U crit ) test, their swimming mode and oxygen cascade typically move to an unsteady state because they adopt an unsteady, burst-and-glide swimming mode...
