MADISON, WI (AP)-- State biologists say a lake trout caught this month is the oldest they've found in northern Wisconsin in recent history.
Wisconsin Public Radio reports that the fish caught near the Apostle Islands of Lake Superior is at least 46 years old, or nearly 100 in human years.
Brad Ray is a senior Lake Superior fisheries biologist. He says the fish was tagged as part of the Department of Natural Resources' fall trout assessment. Ray says the fish has been tagged eight times in the past four decades. He says the trout was 35.5 inches (about 900 millimeters) long. It was tagged and released back into the water.
Officials with the U.S. Fish and Wildlife Service say the oldest lake trout ever recorded was 70 years old.
