... in these fish to help overcome increased fluid viscosity. Increases in swimming speed when both lateral line and visual sensory feedback were removed suggest that lateral line and visual information may be used to regulate swimming speed in P. senegalus , possibly using an internal model of predictions...

... across challenging and variable habitats, we have pursued diverse studies of the comparative biomechanics of amphidromous goby fishes across functional requirements ranging from prey capture and fast-start swimming to adhesion and waterfall climbing. The pan-tropical distribution of these fishes has...

... lakes and interior lakes, all from British Columbia, Canada. We tested for differences in plasma Na + and Cl − , gill Na + /K + -ATPase and H + -ATPase activity and protein abundance as well as changes in body mass and arterial blood pH in fish sampled from the field and acclimated to two different...

Bass ABSTRACT Acoustic behavior is widespread across vertebrates, including fishes. We report robust acoustic displays during aggressive...

...Kota Ishikawa; Heng Wu; Satoshi Mitarai; Amatzia Genin ABSTRACT Feeding by zooplanktivorous fish depends on their foraging movements and the flux of prey to which they are exposed. While prey flux is a linear function of zooplankton density and flow speed, those two factors are expected...

... many fishes, may have resulted from confounding influences of temperature-dependent variation in activity on metabolic rate measurements. We hypothesize that, as demonstrated recently in the winter-dormant cunner ( Tautogolabrus adspersus ), inactivity and the passive physicochemical (Arrhenius) effect...

...Sandy M. Kawano; Richard W. Blob ABSTRACT Amphibious fishes and salamanders are valuable functional analogs for vertebrates that spanned the water–land transition. However, investigations of walking mechanics have focused on terrestrial salamanders and, thus, may better reflect the capabilities...

...A. Kurt Gamperl; Alexander L. Thomas; Douglas A. Syme ABSTRACT Fish increase heart rate ( f H ), not stroke volume ( V S ), when acutely warmed as a way to increase cardiac output ( Q ). To assess whether aspects of myocardial function may have some basis in determining temperature-dependent...

... the cellular basis governing catch-up growth. Experiments consisted of two groups of fish, a control group continuously fed ad libitum , and a group fasted for 2 weeks and then fed for another 2 weeks. We examined how the formation of new muscle fibers and their increase in size were related to muscle...

...Theanuga Chandrapalan; Raymond W. M. Kwong ABSTRACT Trace metals such as iron, copper, zinc and manganese play essential roles in various biological processes in fish, including development, energy metabolism and immune response. At embryonic stages, fish obtain essential metals primarily from...

... their diet. However, diet is often overlooked as a factor that can alter acclimation responses. Using a temperate omnivorous fish, opaleye ( Girella nigricans ), as a model system, we tested the hypotheses that (1) diet can impact the magnitude of thermal acclimation responses and (2) traits vary...

... of cranial muscles as well as the anterior third of the fish's swimming muscles. Seahorses, which have reduced swimming muscles, evolved a unique mechanism for elastic energy storage that powers their suction flows. This mechanism allows seahorses to achieve head rotation speeds that are 50 times faster than...

... acidification on the behaviour of fish vary from very large to none at all, and most of the maladaptive behaviours observed have been attributed to changes in acid–base regulation, leading to changes in ion distribution over neural membranes, and consequently affecting the functioning of gamma-aminobutyric acid...

In the first experiment...

.... Although motorboat traffic has increased in the past few decades, its impact on the communication of fish is still poorly known. The highly vocal Lusitanian toadfish ( Halobatrachus didactylus ) is an excellent model to test the impact of this anthropogenic stressor as it relies on acoustic communication...

Summary: Decreases in trout heart mitochondrial function at high temperatures are due to impaired oxidative phosphorylation and complex I activity and may contribute to set upper thermal limits in this species.
