The Nordic zebrafish network
The Nordic Zebrafish Network (NZN) was established as a result of a workshop meeting in Stockholm, with the aim to bring together scientists and animal caretaker staff to improve the quality of husbandry and science.

In November 2023, almost all zebrafish facilities from the Nordic countries met in Stockholm. For two days, animal caretakers, facility heads and scientists discussed how research in zebrafish and husbandry of this laboratory animal can be optimized and harmonized to facilitate animal welfare and improve the significance and reproducibility of scientific data.
It quickly became clear that the key is to bring together both researchers and animal caretaker staff as optimal husbandry procedures before, during and after scientific studies are equally important as harmonizing and standardizing experiments and data analysis.
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 improve experimental procedures for optimal animal welfare which in turn will create more siginficant, reliable and reproducible scientific data.
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.
Newsletter launch and membership update
Currently, we are not able to offer a membership program, as we have not yet developed dedicated member content. However, we are excited to announce that we are launching a newsletter!
If you work with zebrafish or simply have an interest in them, we warmly invite you to subscribe. The newsletter will include updates, insights, and resources related to zebrafish research and community activities.
To subscribe, please send an email to zebrafish-office@km.ki.se
We also welcome suggestions for topics or content you'd like to see in the newsletter , -feel free to share your ideas with us!
