Not sure of the reason but our lake has attracted a group of cormorants. They are very effective at catching and eating small fish, fish that are about 6 inches long–perch and the recently planted walleye from last fall. Very expensive food for these birds!
There is strong evidence that cormorants cause problems. They destroyed the perch fishing in the Cheneaux Island area near Cedarville/Hessel Michigan. The Fish and Wildlife Service finally issued permits to reduce the number of cormorants nesting on various island near Cedarville.
The presence of cormorants is similar to that of carp. But more boat activity on the lake will encourage them to leave.
