... adaptations. However, in fish, the metabolic impact of regular hypoxic exposure on swimming performance in normoxia is less well understood. Therefore, we experimentally tested whether chronic exposure to constant (30 days at 10% air saturation) or intermittent hypoxia (3 h in normoxia and 21 h in hypoxia, 5...

The effect of wave-driven flow on swimming performance (cumulative escape distance and turning rate...

... sensitivity and plasticity of AS and swimming performance were tested at three test temperatures (28, 32, 36°C). The AS of 28°C-acclimated fish declined with increasing temperature, and the effect was more pronounced in nitrate-exposed individuals. In these fish, declines in AS corresponded with poorer...

... Kinematics Larval fish Swimming performance The fast start is an important manoeuvre in the motion repertoire of many fish species across developmental stages ( Domenici and Blake, 1997 ; Hale et al., 2002 ). Fast starts are commonly divided into two types by the shape changes of the fish during...

We tested the hypothesis that these features improve sustained swimming performance in bonytail by comparing locomotor performance in G. elegans with that of the closely related roundtail chub...

Greater U crit was accompanied by increased tail beat frequency, but there was no change in tail beat amplitude. Hypothyroidism significantly decreased U crit and burst performance...

The results indicate that, at the levels tested, chronic hypercapnia was not a physiological stress for the eel, which can...
