Muskies are occasionally being caught in the Maumee River below Hosey Dam in Fort Wayne, the Indiana Department of Natural Resources said today.
The largest muskie, caught earlier this month, measured 42.5 inches and weighed 28 pounds, the DNR's Division of Fish & Wildlife said in a statement.
Biologists don't know where the muskies are coming from, since none are directly stocked into the river, the statement said. Neither Indiana nor Ohio biologists have stocked in the Maumee watershed recently.
It said "the best guess is they came downstream" via the St. Joseph River from Ball Lake in Steuben County, where muskies were stocked annually until 2009.
Meanwhile Tuesday, the DNR announced that muskies stocked in northwest Allen County’s Lake Everett three years ago will soon be large enough to be kept.
A sampling in April showed that some of the fish are 33 inches long. To be legally kept, muskies must be at least 36 inches long.
Some of the fish are expected to reach that length this summer.
