   COOPERATIVE AGREEMENT LEADS TO HEALTHY GREAT LAKES' TROUT
     
Lake trout fingerlings being reared as part of a hatchery isolation program at 
the Keweenaw Bay Indian Community (Community) Hatchery near L'Anse, Michigan, 
were declared "disease-free" and given a clean bill of health after a recent 
health inspection by the U.S. Fish and Wildlife Service.
     
According to Community Hatchery Manager Mike Donofrio, results from the recent 
inspection -- the first of three scheduled health inspections -- is proof that 
healthy lake trout do exist in Lake Superior and that their offspring can be 
raised successfully at the Community's hatchery.
     
Tribal staff have been nurturing three strains of lake trout since last fall 
when eggs were collected and fertilized at three Lake Superior reefs (Klondike 
Reef, north of Grand Marais, Michigan, Traverse Island Reef in Keweenaw Bay and 
Gull Island Shoal in the Apostle Islands, Wisconsin). 
     
The fingerlings, now four-inches long, will continue growing at about one-half 
to three-quarters of an inch each month.  If the fish remain healthy, they will 
be transferred as 10-inch fish to a Service hatchery in June 1999.
     
"These young fish will become the brood stock for the next generation of Lake 
trout," explained Iron River National Fish Hatchery Manager Dale Bast.  "Their 
offspring will be stocked back into parts of the Great Lakes where wild fish 
aren't reproducing in sufficient numbers.  Along with Sea Lamprey control and 
habitat restoration, periodic stocking of lake trout is critical toward 
restoring wild lake trout populations in Lakes Superior, Huron and Michigan."
     
The fish health inspection was performed by Becky Lasee, a biologist with the 
Service's Fish Health Center in LaCrosse, Wisconsin.  The inspection involved 
collecting 60 fish from each strain and testing each for bacterial and viral 
diseases. "The fingerlings appeared very healthy, with good fat reserves," Lasee
said.  The fingerlings' next health inspection will be in September.
     
The fish-rearing project is part of a two-year cooperative agreement between the
Keweenaw Bay Indian Community and the U.S. Fish and Wildlife Service.  The 
agreement calls for the Community to isolate and raise three strains of Lake 
trout for use as future brood stock.  In exchange, the Service will provide 
yearling Lake and Brook Trout from its hatcheries to Keweenaw Bay and the 
Community's reservation waters.
     
"As fulfillment for the first year of our agreement, the Service planted 106,000
eight-inch yearling lake trout into Keweenaw Bay in April," Donofrio explained. 
"The Service's Genoa Hatchery will also plant 7,000 seven- to eight-inch brook 
trout into streams and inland lakes chosen by the Community for recreation 
fisheries.  Two-thirds of the brook trout have already been planted with the 
remaining third scheduled for planting in August."
     
Members of the media and public are invited to view and photograph the fish by 
contacting Mike Donofrio at (906) 524-5757.
