Zebrafish research facility

A close-up of two small fish swimming towards one another shows the distinctive and vibrant striped pattern of this strain of fish.

The NRC houses an internationally recognized, Canadian Council on Animal Care certified, innovative zebrafish research facility, where we've developed and validated a range of assays, methods and disease models for chemical testing and industry-specific applications.

Genetic research shows high conservation between human genomes and zebrafish, making these tiny fish ideal models for generating biologically relevant information in a diverse range of research fields.

In our facility, researchers from our Aquatic and Crop Resource Development Research Centre use the zebrafish model to identify and characterize the bioactivity and therapeutic potential of known and novel chemicals for use in human disease treatment.

In addition, zebrafish are regarded internationally as a toxicological testing model that can be used for general, preclinical and ecotoxicological testing.

Why team up with us

We provide both standardized and customizable testing models and methods for assessing the bioactivity of a range of substances that contain not only purified compounds but also biological extracts and complex mixtures.

We can accommodate collaborative research and testing of service projects that focus on evaluating toxicological and pharmacological activity in the areas of natural health products and human health therapeutics. Zebrafish provide a powerful model at between 0.1% and 1% of the cost of traditional rodent models, that can help companies prioritize their leads and uncover potential obstacles before reaching the stage of more expensive testing models and methods.

The zebrafish model also has the added advantage of requiring small quantities of test compound, allowing for early identification of lead drug candidates and potential unforeseen complications associated with test material and customized disease models through transgenesis and genome modification.
