Amerikanischer Flussbarsch
Since the disappearance of the alewife, the more balanced lake ecosystem has caused the rebound of yellow perch and walleye populations, due to no competition from the invasive alewife. In early 2017, BFS researchers installed transponder tags in 500 adult walleyes while they spawned in tributaries at the north end of the lake. Afterwards, a warmwater gill net survey was conducted to recapture tagged walleye for a population estimate. Yellow perch were the most numerous captured, followed by walleye. Just over 65 percent of walleye caught were legal to keep (≥ ). Smallmouth bass were the most numerous Centrarchid caught, with over 76 percent being legal (≥ ).
