Study says the favorite food of Great
Lakes salmon is becoming scarce
Posted April 9, 2005
MILWAUKEE A new study says a fish called the alewife
has dramatically dropped in the Great Lakes. And that's
a problem for Great Lakes salmon that love to feed on
The study says the number of adult alewives in Lake Michigan
fell 70 percent between the fall of 2003 and the fall
of 2004. The level is about five percent of what it was
when chinook salmon began to be stocked in the Great Lakes
in the mid-1960s.
On Lake Huron, the alewife population is essentially
Biologists believe the growing number of chinook in the
lakes have gobbled up the fish. Alewives may also have
been hit by invading species and the cold weather.
Biologist Paul Peeters with Wisconsin's Department of
Natural Resources says fisheries experts are now considering
stocking the lakes with fewer salmon, despite the economic
benefits salmon bring.
