Mya Smith of Granger took her first ever turkey during the opening hours of this year’s youth turkey hunting season on April 23. Indiana’s regular spring turkey hunting season began April 27 and runs through May 15. See pages 7 and 10 inside for turkey hunting tips and info!

TURKEY UPDATE: Indiana’s spring turkey season always opens the first Wednesday after April 20, so this year’s April 27 opening date is the latest possible. The last time the season opened on the 27th was in 2005, and Indiana hunters posted a record harvest that year. Another harvest record was set last season when Indiana hunters took 13,742 turkeys. Heavy rains almost certainly kept some hunters from the field on opening weekend this year. How this season’s late start and wet weather will affect this year’s harvest remains to be seen.

BLUEGILL FISHING GOOD AS EVER IN NORTHERN INDIANA LAKES

COLUMBIA CITY – Bluegills are the most abundant and sought-after fish in northern Indiana natural lakes, according to DNR Division of Fish & Wildlife statistics. But perhaps most important to anglers, they are catching as many, if not more, big bluegills now as they did years ago, despite claims that bluegill fishing quality has declined. “Bluegill fishing in our lakes is as good as we’ve ever seen it,” said Jed Pearson, who at age 60 is the oldest fisheries biologist still on the water for the DNR. Pearson, who grew up on

Skinner Lake near Albion in the 1950s and 1960s, has monitored fish populations at hundreds of lakes since the 1970s. His data, along with those from other biologists, show angler catches of 7inch and larger bluegills have remained steady since the 1980s. “Years ago anglers caught 7inch and larger bluegills at an average rate of one per 98 minutes of bluegill fishing. Now they catch them at a slightly faster rate o f one
