... in the holding tank were calculated during periods when the fish were in the field of view of the video camera. Swimming speeds of the fish in the holding tank were determined from the same video footage as the TBF measurements, and were calculated as FL s −1 based on the time taken for the tail tip of a fish...

... (e.g. viscosity) in determining swimming speed is poorly understood. Here we propose a semi-mechanistic model to describe how biological rates, size and the physics of the environment contribute to the temperature dependency of microbial swimming speed. Data on the swimming speed and size...

...Susan L. Gallon; Carol E. Sparling; Jean-Yves Georges; Michael A. Fedak; Martin Biuw; Dave Thompson SUMMARY The duration of breath-hold dives and the available time for foraging in submerged prey patches is ultimately constrained by oxygen balance. There is a close relationship between swim speed...

..., whereas there was no correlation between k high and size. The maximum swimming speeds during vertical excursions (calculated from the pressure data) occurred midway during ascents and averaged ≈2 FL s –1 (where FL =fork length), although speeds as high ≈4–7 FL s –1 were also noted.

... wake flow structures are also examined relative to the swimming motions. At all speeds, the wake contains almost entirely lateral jets of fluid, separated by an unstable shear layer that rapidly breaks down into two vortices. The jet's mean velocity grows with swimming speed, but jet diameter varies...

Unsteady swimming behaviours during the graded exercise, however, caused abrupt and generally short-lived decreases in P v O 2 . For the cold-acclimated (6-10°C)fish, P v O 2 reached a minimum plateau value of 15.3±3.7 torr (1...

Assuming that king penguins dive within their aerobic limit, different approaches to the analysis of the data obtained in the swim channel are discussed to derive the ADL. Swimming speeds observed in the channel ranged from 0.9 to 3.4 m s −1 . Transport costs were...
