LoliTrack v5 Frequency Analyzer to Quantify Ventilation Frequency in Daphnia

Mon, Sept 01 2025

 

 

Our video tracking and behavior analysis software LoliTrack v5 offers a range of different features to study animal movements and behavior. This includes tools to analyze and quantify frequencies in video images, e.g., Zebrafish heart rate, fish tail beat frequency, gill ventilation, insect stridulation, etc.

 

Here, we demonstrate how quick and easy it is to track and analyze the ventilation movements in a Daphnia:

 

We thank you Rorisang Malatsi and Dr Tarryn Lee Botha from the Department of Zoology at University of Johannesburg, for sharing the excellent video recording.

 

In these few steps, important physiological parameters such as thoracic limb activity, heartbeat rates and other pulsing movements in Daphnia or other small or large organisms can be quantified.

If you have videos showing stable pulsing movements, LoliTrack can quantify them.

 

For even more details on the automated frequency analysis tools of LoliTrack, see our video guide: LoliTrack 5 - How to use the Frequency analysis tool. This guide includes examples of quantification of heartbeat rate and estimation of stroke volume by a mahi mahi larvae and tail beat frequencies from the Brazilian fish Brycon amazonicus.

 

If you are interested, but unsure whether the software can analyze the frequency of your specific organism or target and video, please feel free reach out to our product specialist, Dr Louise Vinther Grøn. She will be happy to perform test analysis on your specific video in the software and help you evaluate the possibilities.
