Service haul in a hooked sturgeon in the St. Marys River. As of the end of July, over 200 set lines were deployed and lifted, yielding more than 55 lake sturgeon. Sturgeon caught for the first time have an external "Floy" cinch tag secured to the dorsal fin, along with an internal PIT (passive integrated transponder) tag. Captured sturgeon are measured for total length, fork length, girth, and weight. For more than five years, Lake Superior State University has been collecting data on lake sturgeon, an endangered fish species that inhabits the St. Marys River. Since 2000 they have captured and tagged more than 90 lake sturgeon within the St. Marys estuary.
