(CBS Detroit) – If you’ve caught a trout or salmon in Michigan with its fat fin cut off, the state Department of Natural Resources (DNR) says it may have a tag with important information.
Lake Michigan Basin Coordinator Jay Wesley says fish tag returns help the biologist understand the survival, age and movements of sportfishing fish.

“We are particularly interested in confirming the wild contribution of chinook salmon to the fishery, the movement and wild contribution of rainbow trout in lakes and rivers, and the survival and movement of Atlantic salmon,” said Wesley said.
According to the MNR, several Great Lakes states, including Michigan, tag popular hunting fish such as rainbow trout, chinook salmon, Atlantic salmon brown trout and lake trout. The adipose fin, which is a small fleshy fin behind the larger dorsal fin, is found on a few fish.
Authorities say most trout and salmon with a fat-fin claw have a coded wire tag in their snout.

Anglers who catch an adipose fin fish are invited to turn their heads at a local landing station.
“We have trap clerks in some ports, but there are several areas where we have no staff, including on river systems with unique fisheries, such as Atlantic salmon or rainbow trout. Said Randy Claramunt, Lake Huron Basin Coordinator. “To get enough tag feedback to learn more about these species, we need the help of our fishermen to voluntarily turn heads.”
