Revealing the Secrets of Fish Health: Improving Research on Aging

SciPod

The African turquoise killifish, also called Nothobranchius furzeri, is a small, vibrant freshwater species that is making a big splash in aging research. With our aging populations, research into aging and the mechanisms underlying age-related health issues is increasingly important. Scientists in this valuable field prize the killifish because it has a significantly short lifespan at just six to twelve months, making it an ideal model to study age-related diseases. However, as research on this species grows, so does the need for better care and monitoring of their health. In fact, distinguishing between the natural effects of aging and other health issues in these fish, such as pathogens or disease, is crucial in accurately researching age-related phenomena. Moreover, identifying health issues in laboratory fish could help researchers to better maintain health in their fish stocks, improving both experimental results and animal welfare. This is where Dr. Beate Hoppe and her colleagues at the Leibniz Institute on Aging at the Fritz Lipmann Institute, Jena, Germany, step in, pioneering a comprehensive approach to monitoring and managing killifish health that could revolutionize laboratory fish research.
