What Is DanioVision?

DanioVision™ is a system for high throughput tracking of zebrafish larvae in multi-well plates. It consists of:

The DanioVision Observation Chamber (DVOC-0041)

This chamber contains a transparent holder with backlight that fits an ANSI SBS compatible multi-well microtiter plate, infrared (IR) and white light sources (underneath the microtiter plate), and a Gigabit Ethernet (GigE Vision) video camera. The optical design provides a stable and undistorted top view of each well and a controlled and constant environment within the observation chamber. For technical specifications and for cleaning instructions, see System Specifications.

Tip: You can find your DanioVision version number on the label at the back of the chamber.

EthoVision® XT

Video-tracking software with the Multiple Arenas Module and Trial & Hardware Control Module. Using Trial & Hardware Control, you can adjust the white light stepwise based on time or behavior of your fish. You have the option to connect external devices, such as sound or shock generators.

Note: DanioVision DVOC-0041 works with EthoVision XT 10.1 or newer.

DanioVision Add-Ons

DanioVision Temperature Control Unit

With the DanioVision Temperature Control Unit you can set up a water flow at constant temperature underneath the well-plate. For details, see the Reference Manual - DanioVision Temperature Control Unit DV-TCU, which you can download from the Noldus website.

DanioVision Tapping Device

With the DanioVision Tapping Device you can trigger a startle response in zebrafish. For details, see The DanioVision Tapping Device in this manual.

DanioVision Toplight Unit

With this add-on you can generate top-down light stimuli in your experiments. Four types of light are available: white, red, blue, and green. For details, see The DanioVision Toplight Unit in this manual.

DanioVision with Optogenetics

DanioVision can be provided with one to three LEDs that illuminate the well plates based on your Trial Control protocol. The Optogenetics add-on allows you to accurately control and time the application of optogenetic stimulation to up to 96 individuals simultaneously (one for each well in a 96-well plate). For details, see The DanioVision Optogenetics Add-On.

Custom Solutions

As research evolves, so do research needs. If you are interested in a custom solution, don't hesitate to contact us. A few recent examples of custom solutions include:

• Light-Dark Grid: Commonly used to investigate anxiety behavior in zebrafish. The grid is placed underneath the well plate (available for 6, 12, 24, 48, or 96 wells) and creates a dark and light half in each well. The grid is IR light translucent, leaving the tracking of the zebrafish unaffected.
• High-Speed Camera: DanioVision is equipped with a camera capable of 1000 frames per second. The aim is to measure the startle response of larvae to a stimulus during a Pre-Pulse Inhibition test.
• Split Basin: The DanioVision basin has been modified so that it receives water at two different temperatures. The aim of this solution is to measure temperature preference in zebrafish larvae.
• Ultraviolet Toplight Unit: A modification of the Toplight Unit that shines UV light. Light intensity is controlled by EthoVision XT.
• Turbo-Cooling TCU: A modified Temperature Control Unit which keeps water at a constant temperature of 12° in a room where temperature is about 25°.
