Loligo® Systems is thrilled to announce that our treadmill swim tunnel is being utilized at University of Chicago’s MBL (Marine Biological Laboratory) by Professor Neil Shubin of the University of Chicago, and Dr. Valentina Di Santo from Stockholm.

The treadmill allows Shubin and Di Santo to create controlled flow conditions, simulating a wide range of water velocities, while separately controlling a motorized, transparent belt underneath the fish. Their research aims to provide critical insights into how fish adapt, move, and interact with their environment, contributing to the understanding of ecology, evolution, and conservation.

Want to know more about how Shubin and Di Santo are using our treadmill swim tunnel? Dive into the full story at Welcome to the Fish Gym - Shubin Di Santo Lab.

AutoResp™ v3 is here. Learn more about this major upgrade by watching this short video:

• High Throughput – up to 20 resting chambers or 10 swim tunnels
• NEW hardware for either LAN/Ethernet (cabled) or Bluetooth (wireless) PC communication
• NEW Analysis Outputs with Aerobic Scope, Cost of Transport, EPOC, Maximum Metabolic Rate, etc.
• NEW Allometric Scaling Function
• NEW Temperature Normalization Function
• Independent control of chamber pumps for increased throughput when working with multiple chambers
• Multiple respirometry modes, e.g., time, min/max O₂ levels, min R².
• Re-designed user interface with animated setups and guides
• Comprehensive analysis dashboard with across experiments, treatments, and blanks statistics
• Windows 11 compatible

The latest version of LoliTrack 5 has been released. Version 5.2.0 contains several new features, improvements, and some bug fixes.

IMPORTANT - Loligo® license dongle. LoliTrack 5.2.0 requires a Loligo® USB license dongle. Without the dongle, LoliTrack 5.2.0 will only run in demo mode (i.e., no data export). Previous turquoise Wibu dongles will not unlock LoliTrack 5.2.0. Contact us if you need a Loligo® dongle.

The frequency analyzer. A frequency analyzer allows you to calculate frequencies from video recordings. This is a helpful tool for automated measurements of heart rate, tail beat, ventilation, and other types of frequencies. The Frequency analyzer also allows for volume calculations, which enables you to estimate stroke volume, pumping volume, etc.:

You will find the Frequency analyzer in the main menu.

Another way to utilize the frequency analyzer is in the Analysis tab in Tracking 2D. This tool is especially useful for tail beat frequency analysis. Under the Bend graph, you will find the analyzer in the lower right corner:

Batch processing. You now have the option of batch tracking multiple videos in 2D. This is especially useful if you have multiple videos recorded in the same setup. Simply, track your first video like you normally would, and then apply the same settings to multiple videos. The batch processing window will tell you how much time is left:

Custom object color. To help discriminate between similar looking organisms (e.g., zebrafish) you can now specify the exact color of each tracked object and label it. Click the color box to customize the color according to your liking. The selected color will be reflected on the video preview:

Other features

• LoliTrack 5 now supports more camera models for video recording.
• You can now save arena and treatment setups.
• “Convex hull” area estimation is now a data parameter that can be exported for object in 2D tracking.
• You can now change the thickness of rendered trajectories in 3D.
• You can now choose from three different spine tracking options in the Tracking tab in Tracking 2D.
• Added distortion correction for when videos are distorted, e.g., for wide-angle videos.

Improvements

• Overall speed improvement of tracking and analysis
• Improved performance of the video recorder
• Improved filter options and speed with integration of filter tools from ShuttleSoft 3.

Bug fixes

• Fixed bug which prevented image export in 2D.
• Fixed a bug where exporting videos may take up a lot of memory and crash.
• Fixed a bug where video could not be exported as .avi

RespFest is a conference focused on respirometry. The aim of the meeting is to discuss the latest advances, the difficulties encountered, and optimization of methodologies in model organisms to learn more about this aspect of physiology. RespFest 2023 is free of charge, but requires registration which can be done here:

Natalie Pilakouta, Shaun Killen, Kevin Parsons, and their collaborators used our shuttle box system with the ID 400 mm shuttle tank to study whether exposure to different thermal environments has led to changes in preferred temperatures in the wild in populations of freshwater three-spined sticklebacks (Gasterosteus aculeatus).

Their findings suggest that stickleback from warm and cold natural habitats both prefer the same temperature of 13 ^oC.

If you are a regular visitor on our website, you may have noticed some changes. In other words, we are excited to announce that our new website is now online!

Our website has got a complete makeover compared to the previous, and now 5 years old, website, and we have introduced some needed functionality. You now have easier access from the homepage to our large resource library with quick guides, video tutorials, FAQs and more as well as a quick overview of the latest published papers. On the product pages, you will also find that features, specifications, resources are now easier to find. Simply click the side-menu to switch between the content pages for each product:

Important information like Product #, Customs tariff #, and Shipping weight is now more visible:

A new search functionality has been added, so that you can search all the content on our website directly from the search bar in the top menu. It is now easier than ever to find that specific quick guide, published paper, or software download page.

We will also gradually introduce 3D viewing capabilities for product showcasing and as resources for system setup.

We hope you enjoy our new website as much as we do!

The Europhysiology 2022 meeting begins tomorrow! We are thrilled to be sponsoring this exciting meeting, which takes place in Copenhagen from the 16^th-18^th of September.
