As anglers hit Lake Superior, the Michigan Department of Natural Resources is asking that you keep an eye out for clipped Chinook. This means the fish is missing the adipose fins.In 2012, the Fisheries Department began stocking clipped Chinook salmon. This is to track how many fish are caught that were raised in hatcheries. Clipping was done on nearly 750,000 fish. These fish were stocked at Black River Harbor, in the Big Iron River near Silver City, and in the Dead and Carp Rivers near Marquette. However, they may be caught anywhere in Lake Superior.
Creel clerks will be at boat landings and fishing locations through the summer gathering information from anglers.
The DNR says the adipose fin is the small fleshy lobe found on the back of the fish, just forward of the tail fin.
"What we're looking for is to just check and see what is the proportion of fish people are catching that are coming from the hatchery and which ones are naturally reproducing," says Debbie Munson Badini from the Michigan Department of Natural Resources. "That will tell us where do we need to put our money."
If caught, the fish do not need any special attention. The DNR will be asking anglers at docks whether or not the fish they caught have their fins clipped or not.
However if one of these fish is caught on Lake Michigan, it is asked that you cut off the snout of the Chinook and give it to the DNR because those fish have been implanted with tags.
