Milestone Approaches In Effort To Restore Michigan Grayling

LANSING (CBS DETROIT/AP) — A mission to return the Arctic grayling to Michigan waters is nearing a milestone. The grayling is a species of freshwater fish in the salmon

Juvenile grayling are scheduled to arrive soon at the Oden State Fish Hatchery in Emmet County, where an ultraviolet water disinfection system recently was installed.

Fish production manager Ed Eisch of the Department of Natural Resources says the system will prevent fish already in the area from being infected by viruses or bacteria that the newly arrived grayling might bring along.

They were collected as eggs in Alaska and have been kept at Michigan State University.

The juvenile fish will be reared in isolation at Oden. Once cleared by health testing, they'll be transferred to Marquette State Fish Hatchery to continue maturing.

Grayling are native to Michigan but died out because of logging and overfishing.
