Field respirometry in the Leonard Lab
The research group from the Jill Leonard’s lab at Northern Michigan University in Marquette, MI, is taking Loligo respirometry into the field. The objective is to evaluate resting and maximal metabolic rate in wild brook trout with the goal of classifying individual fish by metabolic ranking. To accomplish this, Jill’s team is taking a Loligo 4-chambered intermittent flow system to the streamside.
“We have validated field measurement protocols for our metrics with matching lab experiments that compare to traditional experimental parameters. The system will run on a generator for power and use native river water for experimentation and temperature control. Once the fish are ranked, they will be PIT tagged and released back to their native river where we will monitor movement behaviors with stationary and mobile antenna systems.” says Jill Leonard.
Prior research has identified a continuum of movement strategies in the species ranging from stationed at a specific site to wandering throughout the entire river to true migration. This research seeks to correlate movement behaviors with physiological metrics at the individual level to help understand why different life history strategies are selected within partially migrant populations.

ICBF 2018 meeting
Please meet Loligo® Systems at the 13th International Congress on the Biology of Fish in Calgary, Alberta.
The biennial event is expected to attract around 400 delegates from all over the globe. Symposia range in topics related to fish biology, including behavior, stress physiology, ion regulation, swimming and energetics, toxicants, growth and metabolism, genomics, impact of climate change, use of zebrafish as a model for biomedical research and many more.
ICBF 2018 will take place from July 15th – 19th at University of Calgary.

New MicroResp® software and quick guide
We have just launched a new version of our MicroResp® software with added features and improvements for better performance, and a handy quick guide for the MicroResp® systems.
New software features:
- “Show All”-graph showing real-time oxygen traces for all 24 wells during experiments, with different colors for each user-defined treatment
- Guides for lower/upper limits and wait time on experiment graphs
- More user choices for sampling rate
Please download the new quick guide.
We hope that the guide will help new and current users.
Best of luck with your future microplate projects!

Zebrafish critical swimming speed
Dr. Maria Bertuzzi & Dr. Konstantinos Ampatzis from Karolinska Institutet used a Loligo® 5 L swim tunnel respirometer to test the critical swimming speed (Ucrit) in multiple adult zebrafish. The researchers investigated the functional flexibility of motoneurons and how the neurons execute locomotion at different speeds. Specifically, Bertuzzi & Ampatzis found that cholinergic interneurons are present in the zebrafish spinal cord and differentially control the excitability of distinct classes of motoneurons (slow, intermediate and fast) in a muscarinic dependent manner. Their unexpected findings are published in Nature’s Scientific Reports. Scientific Reports.
