... flume (4100 l; freestream flow at 65 cm s −1 ) and created vortices using 45 deg wing dams of varying size (small, 15 cm; medium, 31 cm; large, 48 cm). We monitored microhabitat selection and swimming kinematics of individual trout and measured the flow field in the wake of wing dams using time-resolved...

... by swimming rapidly to the water surface to achieve an escape velocity. Previous research on spinner dolphins demonstrated the capability of leaping and completing multiple spins around their longitudinal axis with high angular velocities. This prior research suggested the slender body morphology of spinner...

...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...

... 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...

... (‘stereotypy’) as a consequence of having a smaller and less complex environment available for them to explore ( Bennett et al., 2015 ). Despite this difference, captive dolphins maintain the same capability for maximum swimming speeds compared with free-living individuals ( Rohr et al., 2002 ). In some...

We found that as body size increases, absolute maneuvering performance...

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...

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...

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...
