Loligo® Systems develops research equipment for aquatic biology. Our products allow scientists all over the world to excel in the fields of swimming performance, respirometry, blood physiology and behavior analysis in a diversity of marine and freshwater organisms. We offer customized solutions as well as free scientific advice and support to anyone in need. Loligo® Systems is here to help.
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.
This 360º swim tunnel is a specialized version of a standard Loligo® swim tunnel. A wider middle section houses a dry compartment for a camera to film swimming animals from inside the test section through a thin acrylic wall. This means that the swimming animal can be viewed and filmed from all four angles: left, right, from above, and from underneath, and all through single acrylic walls for optimum optical quality.
Hence, we named this baby the 360º swim tunnel!

DPTV 2 is fast and intuitive video tracking software for non-invasive measurements of water velocity in rectilinear flows. DPTV 2 is the ideal tool for water velocity calibrations in 170 mL and 1500 mL Loligo® swim tunnels and other Blazka-type swim tunnels with limited access or space for flow probes. The software is also part of our flow tracking system.
The velocity measurements are based on 2D video tracking of green laser illuminated fluorescent spheres with neutral buoyancy. DPTV 2 will automatically calculate average flow velocities and direction from video images, and provide a calibration file that can be used directly in our different swim tunnel software. You can also perform a manual velocity calibration using recorded video files from your own camera or from a camera system from us.
There is a free DPTV 2 demo available (see FILES/DOCUMENTS below).
Here is a quick video tutorial of DPTV 2.
