Fish Used for Experimentation

overview

There is no official estimate of the amount of fish used in research. In the US, the Animal Welfare Act, which provides some protections to animals used in research, does not require facilities to keep records of the number of fish used in experimentation. The rough estimate is that half of animals used in research are fish.

Zebrafish are widely used in research because  they are bred to be transparent. They are also easier to care for and produce more offspring than rodents. Using zebrafish embryos is also considered a replacement method for animal experiments, even though fish can feel pain like other animals.

This page will be updated as more information becomes available.
