Aquatic Animal Welfare

Zebrafish Welfare in Aquaculture and Research

Zebrafish are widely used in research and increasingly in aquaculture, with growing evidence of their capacity for pain and stress responses.

Key Facts

Zebrafish are sentient vertebrates capable of nociception
Standard housing densities in research can cause chronic stress
Water quality, temperature and social structure affect zebrafish welfare
Genetic models of disease in zebrafish may cause severe phenotypes
The 3Rs framework applies to zebrafish used in research

Welfare Considerations

Zebrafish welfare has historically been undervalued relative to mammalian research species. Their sentience and complex social behaviour require appropriate housing standards, environmental enrichment and humane endpoints in research protocols.

What You Can Do

Support research institutions that apply 3Rs principles to zebrafish
Advocate for zebrafish welfare guidelines in research funding criteria
Encourage publication of welfare outcomes in zebrafish research
