LoliTrack v5 Frequency Analyzer to Quantify Ventilation Frequency in Daphnia
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.

New Update – Video Recorder Version 1.2
We have released an updated version of our free Video Recorder software for recording and editing video files.
New features and improvements:
You can now adjust the video camera exposure time directly in the software. This is a great help when using various light panels for back illumination, e.g., as with our CentriTower system.
Another new feature is the ability to change the frame rate for two synchronized video cameras (e.g., for 3D tracking), rather than just for one at a time. Synchronized video files are now exported with distinct/different names, so that you can use them for 3D tracking, e.g., in LoliTrack.
You can download the latest version here:
The software continues to support most video cameras but offers more functionality if using our video cameras from IDS Imaging in Germany.
Please note that this version of Video Recorder is not compatible with the older uEye video cameras from IDS Imaging.

How to measure respiration rates in Drosophila
In this article, we showcase how the microplate respirometry system provides an easy to use, high throughput respirometry tool for determining oxygen consumption rates in various life stages of terrestrial insects, here using fruit flies (Drosophila melanogaster and Drosophila littoralis). The project was performed at Aarhus University in Denmark in collaboration with Prof Jesper G. Sorensen at Aarhus University in Denmark.
The first part of the project looked at the respiration rates in eggs, third instar larvae, and pupae of D. melanogaster. The fruit flies were maintained at 19 °C, and were in the following life stages:
- melanogaster eggs: 0-12 hours old
- melanogaster larvae: 6-7 days since egg stage
- melanogaster pupae: 8-9 days since egg stage
The first trial had 10 x eggs + 10 x pupae (+ 4 x blanks). The eggs and pupae were transferred directly from their food solution/colony and placed individually in a well in the 80 µl glass microplate. The wells were then closed using gas-tight non-toxic sealing film, and placed onto the microplate reader. The microplate reader and glass plate were then covered with an opaque plastic box, to prevent ambient light from interfering with the optical oxygen sensor inside each well, and left at room temperature (21 °C). Here is a picture of the setup:
The MicroResp™ v1.1 software was used to calibrate the oxygen sensors, set up the plate and experiment settings, and to log data. Here are the exported data graphs:
Oxygen data graph for 10 x eggs (dark golden), 10 x pupae (purple), and 4 x blanks (black) measured over 2 hours and 18 min.
The next trial used 20 x third instar larvae (dark cyan) and 4 x blanks (black), and data was logged for 1 hour and 35 min.:
A data plot of the MO2 values shows oxygen consumption rates in the pupae (second from right) and larvae (first from right) but no consumption was detected in the eggs and blanks (far left):
The next part of the project investigated the respiration rates in adult fruit flies, here D. littoralis. Besides determining the oxygen consumption rates of adult individuals, we also wanted to look at the effects on MO2 from anesthetization with CO2 – a common anesthetic used when handling live fruit flies. An individual adult fruit fly was transferred using an aspirator tube from their maintenance chamber at 21 °C and then directly into a well or anesthetized for 30 sec. with CO2 prior to transfer. The 200 µl glass plate was then closed with sealing film and placed under a box.
The MicroResp™ v1.1 software was used to calibrate the oxygen sensors, set up the plate and experiment settings, and to log data. Here are the exported data graphs:
Oxygen data graph for 12 x adult flies (green), 8 x adult flies anesthetized with CO2 (blue), and 4 x blanks (black) measured over 4 hours and 41 min. A data plot of the MO2 values shows no apparent difference between non-anesthetized (mid) and anesthetized individuals (right):
In conclusion, the microplate respirometry system was able to dertemine oxygen consumption rates in various life stages of fruit flies in a relative short period of time.

Introducing the new LoliGO App
We are excited to offer users of Loligo® software this new free and useful tool.
The LoliGO App is a smartphone application for Android and iOS that allows users to remotely monitor their experiments while having the option of getting push notifications in case of power outs in the lab, computer failures, or alarms based on water quality thresholds – like if the temperature gets critically high in your respirometry chambers.
The LoliGO App uses a secure cloud-based service to handle data sent from the Loligo® software and to the App. Users can set up a user profile, and multiple users can access the same user profile at the same time (if they know the password!) aka you can have a shared lab profile.
You cannot alter or stop experiments from the app, and you cannot export or otherwise gain access to the raw data from the app. Completed experiment data will be automatically deleted from the app after 14 days.
The LoliGO App is free to use, and is currently compatible with AutoResp™ v3, and the app will be available with future updates of other Loligo® software soon.
Download the latest version of the LoliGO App:
- LoliGO for Android (on Google Play)
- LoliGO for iOS (on App Store)

If you are looking for a solid fish respirometry and hypoxia paper with thorough explanations on methods, protocols, and data analysis, look no further than this 2023 publication by LeeAnn Frank, Joseph Serafy, and Prof. Martin Grosell from the Rosenstiel School of Marine, Atmospheric, and Earth Science, University of Miami.
A large aerobic scope and complex regulatory abilities confer hypoxia tolerance in larval toadfish, Opsanus beta, across a wide thermal range
Frank, LeeAnn; Serafy, Joseph; Grosell, Martin (2023)
Science of The Total Environment
The team of researchers provides an easy-to-follow methodical description on how to measure standard metabolic rate (SMR), routine metabolic rate (RMR), maximum metabolic rate (MMR), and aerobic scope (absolute and factorial) as well as how to assess the regulation index, P50, and Excessive Post Hypoxia Consumption (EPHOC) data in larval toadfish (Opsanus beta) over a range of their environmental temperatures. In addition to the detailed materials and method section, the authors supply the article with a manageable overview on how to analyze such respirometry data and which data parameters to include. The data are effectively illustrated using an assortment of data graphs, plots, and tables.
