The Treadmill swim tunnel is a specialized version of a standard Loligo® swim tunnel. The floor of the test section is a motorized belt, and speed can be controlled independent of the water velocity, so that you can force-exercise flatfish, rays, crustaceans or other benthic animals that walk rather than swim.
The moving belt is made from a transparent food-grade rubber material (TPE) enabling video filming from below, and filming can be done through the planar acrylic lid and outer sidewall too.
The compact design and small volume still allow for respirometric methods.
Applications include physiology, behavior, bioenergetics, biomechanics or kinematic measurements on walking fish/inverts.
Here is a video of the treadmill in motion.
