Wild fish host new viruses, including a coronavirus cousin
Researchers have detected multiple new viruses in wild sport fish in Wisconsin, revealing a surprising diversity of pathogens.
Danielle Kaeding reports for Wisconsin Public Radio.
In short:
- The University of Wisconsin study found 19 viruses in fish, 17 of which were previously unknown, highlighting the diversity of aquatic pathogens.
- Among the viruses discovered is a distant relative of the coronavirus, stressing the importance of understanding fish health for ecosystem management.
- The study aids fishery management and conservation efforts by identifying viruses that could impact fish health and population stability.
Key quote:
“I wouldn’t be surprised if some of the viruses we found, or some we haven’t found yet, pop up in the future when things like climate change get worse or we have water quality declines for any reason.”
— Tony Goldberg, professor of epidemiology at the University of Wisconsin's School of Veterinary Medicine.
Why this matters:
This research reinforces the importance of monitoring wildlife health as a reflection of ecosystem stability and environmental quality. We need to change how we relate to wildlife, putting their health, and our own, before commercial interests.
