Fish Survey

Here is a summary of what DNR found based on my professional opinion as a DNR fisheries biologist.  This late spring electrofishing survey is most valuable when assessing Largemouth Bass and Bluegill, which also appear to be the two most abundant species in Long Lake.  Largemouth Bass numbers seemed to have increased since implementing a no-minimum length limit in 2012.  At the same time, growth has improved for bass at most ages when compared to 2009.  However, if lake residents want bigger bass, harvesting small bass should continue to be a goal for those who fish the lake.  Bluegill numbers increased while average size decreased.  This change may be related to our survey timing as we sampled the lake 6/13.  This is later than typical bluegill spawning peak in our area.  It also may reflect increased harvest since 2009.  If this is the case, bluegill sizes should rebound quickly given the high number of bass to keep small bluegill numbers in check.  One small walleye was collected suggesting a remnant population exists in Long Lake.  However, past stockings (1999, 2001) did not show good survival results in DNR surveys.  For this reason, future walleye stocking is not recommended.  Northern Pike and Black Crappie are likely more abundant than this survey suggests.  This is because of survey timing.  These species spawn much earlier than when we surveyed and likely were in deeper water at the time of the survey.  Pumpkinseed, Yellow Perch, Hybrid Sunfish and Rock Bass are present at lower rates in Long Lake based on this data.
