The Nordic zebrafish network

The Nordic Zebrafish Network (NZN) places equal emphasis on husbandry practices and scientific investigation. Our overarching goal is to harmonize husbandry procedures and biosafety strategies, while also providing a platform for education and training of zebrafish care staff.

Our key focus areas

Promoting 3R strategies

We actively encourage the adoption of 3R strategies in zebrafish research (Replacement, Reduction, and Refinement). By emphasizing the 3Rs, we aim to minimize the use of animals, alleviate their pain and distress, and enhance experimental procedures for improved animal welfare. 

Facilitating knowledge sharing

NZN serves as a hub for researchers to exchange experiences, share best practices, and discuss challenges related to zebrafish research. Through collaboration, we can collectively learn, avoid pitfalls, and accelerate scientific discoveries.

Standardized protocols development

To enhance research quality and comparability, we are committed to developing standardized protocols for zebrafish studies. These protocols will ensure reproducibility across different laboratories, reduce variability in experimental outcomes, and advance our understanding of zebrafish biology.


NZN warmly welcomes individuals interested in or working with zebrafish. Whether you’re a scientist, educator, or enthusiast, join us in our mission to advance zebrafish research and care. Please contact Cesilie Røtnes Amundsen or Lars Bräutigam to become a member.
