Larval zebrafish are an invaluable tool for neuroscientists, who use the tiny, transparent fish to probe how the brain ...

Researchers have found that larval zebrafish quickly learn to identify predators and find easy ways to avoid them. Larval zebrafish learn such things robustly just five days after beginning their ...

A new fully automated in vivo screening system (AISS) has been developed to transform drug evaluation by enabling rapid, precise, and non-invasive multi-organ imaging in zebrafish. Integrating cutting ...

To tackle it, the authors of a study published last week (January 16) in Cell imaged large swaths of the larval zebrafish brain as the animals decided which way to move their tails to avoid an ...

Nicotine-seeking behavior in larval zebrafish, Poster Presentation; 2019 Midwest Zebrafish Meeting, University of Kentucky, Lexington, KY, June 7-9, 2019 Henning Schneider, Anna Pearson (DPU ’20) , ...

They are therefore easy to keep in large numbers in aquariums. A zebrafish couple can produce 300 eggs per week. The larvae hatch two days after fertilization; five days later all the vital organs are ...

The small size and optical transparence of zebrafish embryos and larvae greatly facilitate modern intravital microscopic phenotyping of these experimentally tractable laboratory animals.

Published (DOI: 10.1038/s41378-024-00852-9) in Microsystems & Nanoengineering on January 27, 2025, the study showcases how the AISS can automate zebrafish larvae manipulation, allowing for precise ...

"Zebrafish larvae are particularly suitable for our studies because they are almost completely transparent, allowing us to observe the development of their inner organs," explains Mulzer.

Janelia researchers thought that traditional ways of testing learning in larval zebrafish in the lab -- where the conditions were far from what the fish would encounter in the wild -- might not be ...
