This 360^º 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 360^º swim tunnel!

The compact design and small volume still allow for respirometric methods. Applications include physiology, behavior, bioenergetics, biomechanics or kinematic measurements.

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.

Open flume tank system for force-swimming individuals or groups of zebrafish fry-juveniles (or similar) in a controlled recti-linear flow. Water velocity can be adjusted from 2-28 cm/s with a diaphragm valve or by changing the (included) pump flow rate. The exact flow is monitored in real-time with an inline paddlewheel (inductive) flow sensor and a transmitter with a digital display. Swimming animals can be filmed from left and right as well as from above and below. The open test section makes it easy to add or remove specimens. Typical applications include zebrafish phenotyping, swimming performance, exercise physiology, behavior etc. in freshwater or seawater species.

NOTE: The diaphragm valve and paddlewheel flow sensor is included. Mesh diameter size (in honeycomb and metal mesh) can be changed upon request. Contact us for more information.

Loligo^® swim tunnels have been developed for measuring the physiology, energetics, behavior, biomechanics and kinematics of swimming fish, through years of research and laboratory use. Applications also include studies of fluids, visualization of flow around objects, hydraulics, and public display of aquatic wildlife. The unique and compact design allows enough space for "free" swimming and an adequate volume for reliable oxygen consumption measurements.

AutoSwim is user-friendly Windows software for automated control of water velocity in up to seven Loligo^® swim tunnels from a single PC. It requires the use of our wireless swim tunnel controller DAQ-BT, and then water velocity can be calibrated, converted, corrected and controlled in any unit and in any way, i.e. for swimming velocities in BL/sec, for solid blocking correction, and for automated user-defined protocols.

AutoSwim software is made for swim tunnel applications not requiring oxygen consumption measurements, as our AutoResp™ software will then be the software to use.
