“…1. The cost function f in (4) shows that the fish is more high speed-averse for larger n, because it more rapidly grows for larger n. The cost function f in (4) is convex and increasing with respect to u; which is in good accordance with the conventional experimental results on swimming behavior of fishes (Brodersen et al 2008;Cucco et al 2012;Mori et al 2015;Roche et al 2013;Svendsen et al 2010;Yoshioka et al 2016a). The objective function is rewritten with (2) as…”

A simple game-theoretic model for upstream fish migration, which is a key element in life history of diadromous fishes, is proposed. Foundation of the model is a minimization problem on the cost of migration with the swimming speed and school size as the variables to be simultaneously optimized. Finding the optimizer ultimately reduces to solving a self-consistency equation without explicit solutions. Mathematical analytical results lead to the sufficient condition that the self-consistency equation has a unique solution, which turns out to be identified with the condition where the unique optimizer exists. Behavior of the optimizer is analyzed both mathematically and numerically to show its biophysical and ecological consequences. The analytical results demonstrate reasonable agreement between the present mathematical model and the theoretical and experimental results of upstream migration of fish schools reported in the past research.

Oxygen consumption also continues to increase until U crit is reached (Dalziel et al, 2012a), as has been observed in striped surfperch, another labriform swimmer (Svendsen et al, 2010). Together, these observations suggest that U crit is a good measure of maximal aerobic swimming performance in sticklebacks.…”

“…In threespine sticklebacks, U crit is also tightly correlated with the gait transition from pectoral fin rowing to a combination of pectoral fin rowing and caudal bursts (Dalziel et al, 2012a), which is suggested to be a good measure of sustained swimming speed (e.g. Korsmeyer et al, 2002;Svendsen et al, 2010). Oxygen consumption also continues to increase until U crit is reached (Dalziel et al, 2012a), as has been observed in striped surfperch, another labriform swimmer (Svendsen et al, 2010).…”

SUMMARYDetermining which underlying traits contribute to differences in whole-animal performance can be difficult when many traits differ between individuals with high and low capacities. We have previously found that migratory (anadromous marine) and nonmigratory (stream-resident) threespine stickleback (Gasterosteus aculeatus) populations have genetically based differences in prolonged swimming performance (U crit ) that are associated with divergence of a number of candidate morphological and physiological traits (pectoral fin size and shape, body shape, pectoral muscle and heart size, and pectoral muscle metabolic enzyme activities). Here, we use F2 hybrid crosses to determine which traits are correlated with U crit when expressed in a largely randomized genetic background and a range of trait values for other divergent traits. We found that four of our 12 candidate traits were positively correlated with U crit in F2 hybrids and that the combined effects of ventricle mass, pectoral adductor mass and adductor citrate synthase activity accounted for 17.9% of the variation in U crit . These data provide additional support for a causal role of muscle and heart size in mediating intraspecific differences in U crit , but indicate that many candidate morphological and biochemical traits do not have a strong effect on U crit when disassociated from other divergent traits. However, the limited variation in U crit in our F2 hybrid families may have decreased our ability to detect correlations among these candidate traits and U crit . These data suggest that many traits, interactions among traits and traits not measured in this study affect prolonged swimming performance in threespine stickleback.

“…The post-exercise recovery period or oxygen debt is directly related to the intensity of exercise (Svendsen et al, 2010). There are obvious advantages to reducing Tetanus stress (A) was significantly greater at 25°C test temperature than at 15°C regardless of acclimation treatment (significant differences between test temperatures are indicated by horizontal bars with different letters).…”

Metabolic energy (ATP) supply to muscle is essential to support activity and behaviour. It is expected, therefore, that there is strong selection to maximise muscle power output for a given rate of ATP use. However, the viscosity and stiffness of muscle increases with a decrease in temperature, which means that more ATP may be required to achieve a given work output. Here, we tested the hypothesis that ATP use increases at lower temperatures for a given power output in Xenopus laevis. To account for temperature variation at different time scales, we considered the interaction between acclimation for 4 weeks (to 15 or 25°C) and acute exposure to these temperatures. Cold-acclimated frogs had greater sprint speed at 15°C than warm-acclimated animals. However, acclimation temperature did not affect isolated gastrocnemius muscle biomechanics. Isolated muscle produced greater tetanus force, and faster isometric force generation and relaxation, and generated more work loop power at 25°C than at 15°C acute test temperature. Oxygen consumption of isolated muscle at rest did not change with test temperature, but oxygen consumption while muscle was performing work was significantly higher at 15°C than at 25°C, regardless of acclimation conditions. Muscle therefore consumed significantly more oxygen at 15°C for a given work output than at 25°C, and plastic responses did not modify this thermodynamic effect. The metabolic cost of muscle performance and activity therefore increased with a decrease in temperature. To maintain activity across a range of temperature, animals must increase ATP production or face an allocation trade-off at lower temperatures. Our data demonstrate the potential energetic benefits of warming up muscle before activity, which is seen in diverse groups of animals such as bees, which warm flight muscle before take-off, and humans performing warm ups before exercise.
