The Nothobranchius Symposium 2021 is a biennial meeting that serves as a platform for researchers with an interest in all aspects of Nothobranchius biology from biomedical to ecological research to meet and discuss ideas.

We are sponsoring the symposium which takes place virtually on Zoom, on 3-4 June, 2021, in order to support this interesting scientific community.

We are supporting the Canadian Society of Zoologists 2021 Virtual Meeting as Gold level sponsors.

The CSZ takes place from May 17-21, and the meeting will include award lectures, student and postdoc award competitions, symposia, section meetings, discussion forums and networking events, and the awards ceremony.

Contributed oral and poster presentations will be viewable on-demand, starting the week before the live program begins.

A new modified version of our 30 L swim tunnel, with a motorized transparent belt that can be operated independently of the water flow, is now available.

We call it a Treadmill Swim Tunnel, and you can use it to force-exercise walking fish like rays or gurnards, crustaceans like crayfish or lobster, and other benthic animals at various speeds.

The moving floor is made from transparent food-grade rubber material allowing filming from below, and the planar lid and wall surrounding the test section also allows for filming/viewing from the top and left side.

The water flow can be adjusted independently from 5-175 cm/sec as for our standard 30 L swim tunnel, by means of a second motor and control box.

If you are an early-career researcher (graduate student or postdoc) interested in fish locomotion and ecophysiology, do not miss this great opportunity. Applications will be accepted for two more weeks (until mid-March 2021).

Friday Harbor Labs are offering a Fish Swimming course taught by Paolo Domenici, John Steffensen and Jacob Johansen for graduate students and postdocs between July 19th and August 20^th, 2021.

Applications will be accepted during the first two weeks of March 2021. Early applications are encouraged, and financial aid is available to students from all countries.

Based on positive user feedback, we recommend using PCR film, rather than parafilm, to seal our glass microplates when used for closed respirometry. The PCR sealing film that we now offer is a self-sticking clear polyester sheet that simply sticks onto the glass microplate providing a water-tight seal minimizing sample evaporation and contamination.

Watch this tutorial on how to apply the PCR film:

Inspired by feedback from the famous Poss Lab at Duke University, we are now offering a new quick release lid for our 5 L and 10 L swim tunnels for fast and effortless addition/removal of animals. This is especially relevant for users that are force-exercising large groups of zebrafish and want to get the fatigued specimens out in no time and without disturbing the rest of the fish or having to stop the experiment.

The lid opening is placed right next to the downstream grid where fatigued fish tend to end up during swimming performance tests. This means that if one or multiple animals get stuck on the grid during swimming, the animals can be quickly removed without having to unscrew the entire lid.

We have created the complete video tutorial for our new DPTV 2 software. The video shows how easy it is to perform an automated water velocity calibration in one of our mini swim tunnels using a uEye camera and a DAQ-BT device, and how you can perform a manual calibration as well as record your own videos.

We hope you like it. Feel free to contact us if you have any questions or want to know more about the DPTV 2 software.

We have introduced a new product to our portfolio.

This Open flume tank is for force-swimming individual or groups of fry-juvenile zebrafish; or anything aquatic and similar sized, for that matter. This system is ideal for zebrafish phenotyping, swimming performance, exercise physiology, behavior etc. in freshwater or seawater species. The water velocity (= swimming speed) can be adjusted using the included diaphragm valve and paddlewheel flow sensor, and can be adjusted from 2-28 cm/s. The tank has an open test section meaning that introducing, accessing, and removing the animal is a breeze. The section provides a clear view (e.g., for filming) from four angles (left, right, above and below). It is also possible to adjust the water depth by switching between the included weirs.

The open flume tank was developed with versatility and high-throughput in mind.
