To identify the fingerlings which have been implanted with a CWT, the adipose fin is removed as shown below. Starting in 2010, Wisconsin, along with other agencies, began a mass marking project of Chinook salmon with the main objective of trying to determine the number of naturally reproduced Chinook salmon in Lakes Michigan and Huron.

These fin clip patterns are for the Lake Michigan and Green Bay waters of the State of Wisconsin only. Trout and salmon with other fin clip patterns can originate from other states and would be considered “strays” in Wisconsin waters. Fin regeneration makes some clips difficult to see. Note:

Prior to 2011, lake trout stocked were given other fin clips (e.g. left ventral, right ventral, etc.). Although fish can be missed during the process of fin-clipping, and regeneration of fins can occur, we have seen evidence of natural reproduction of lake trout in Lake Michigan for decades but more have been detected since 2011.

Urban storm water runoff contains pollutants from roads, parking lots, construction sites, industrial storage yards and lawns.

While the lake sturgeon isn't likely to be mistaken for Jaws, it does have a heterocercal (sharklike with the upper lobe being longer than the lower) caudal (tail) fin.
