Lake Superior State University fisheries and wildlife management alumnus and Michigan Department of Natural Resources fisheries technician Dan Operhall empties about 20,000 Atlantic salmon fingerlings into a holding pen at the LSSU fish hatchery in Sault Ste. Marie, Michigan on May 9th.
The fish were reared at the Platte River hatchery near Honor, MI, on Lake Michigan. The salmon fry need about a month to acclimate to the much chillier waters (yesterday’s temperature was 36°F) of the Lake Superior-fed St. Mary’s River.
About 45,000 Atlantics, including 25,000 raised by LSSU, will be released in June.
