Michigan: UV system in place, Oden hatchery readies for Arctic grayling

Michigan is one step closer to bringing Arctic grayling back to state waters. The ultraviolet water disinfection system at Oden State Fish Hatchery in Emmet County has been installed, meaning the facility is ready to welcome juvenile Arctic grayling.
“With the completion of this project, we can protect the fish populations in the inland waterway – the series of rivers and inland lakes that the rearing water flows into – from any pathogens that may inadvertently arrive with these fish,” said Ed Eisch, the DNR’s fish production manager. “We don’t anticipate any issues, but we definitely want to err on the conservative side when it comes to the possibility of introducing new pathogens.”
The UV system is critical for the long-term process of cultivating Michigan’s Arctic grayling broodstock (mature fish used for breeding), a goal of the Michigan Arctic Grayling Initiative.
This project was generously supported through grants and donations by private donors. More than $350,000 was raised to upgrade Oden’s isolated rearing facility, including engineering and construction costs. Read more
