Summary
The October 1961 Beaver Beacon reported that the usual Beaver Island perch run had almost completely disappeared. Art Larsen, described as a lifelong resident of Garden and Beaver Islands, said he could not recall a comparable absence; the article says other Lake Michigan areas reported little or no perch as well.
Evidence and limits
This is a contemporary observation, not a fishery survey, catch series, or explanation of the cause.
