... of Biologists Ltd 2018 http://www.biologists.com/user-licence-1-1/ Summary: Fish head width, which varies widely across species, influences how the lateral line canal system can sense both steady and vortical flows. Lateral line canal system Head morphology Pressure sensing Vortex street...

...–55,000. Digital particle image velocimetry showed that increasing l/D decreased the strength of the vortex street by an average of 53% and decreased the frequency that vortices were shed by ∼20% for all speeds. Trout were able to Kármán gait behind all cylinder treatments despite these differences...

...Otar Akanyeti; James C. Liao SUMMARY A mechanistic understanding of how fishes swim in unsteady flows is challenging despite its prevalence in nature. Previous kinematic studies of fish Kármán gaiting in a vortex street behind a cylinder only report time-averaged measurements, precluding our...

... that not all fish positioned in a vortex street are Kármán gaiting. By far the highest probability of Kármán gaiting occurred at intermediate flow speeds between 30 and 70 cm s −1 . We show that trout Kármán gait in a region of the cylinder wake where the velocity deficit is about 40% of the nominal flow. We...

... locomotory costs by exploiting flow refugia has been shown in the field( Puckett and Dill, 1985 ; Heggenes, 1988 ; McMahon and Gordon, 1989 ; Fausch, 1993 ), the results of this paper detail the ability of trout to hold station by (1) adopting a novel gait to utilize the vortex street behind a cylinder...
