Is Lake Michigan Following Lake Huron in Salmon Decline?

You don’t have to hang around fishing circles too long before someone speaks of the glory days salmon fishing on Lake Huron.  Unfortunately salmon fishing on Lake Huron isn’t what it used to be and will likely never return to its former glory.  The decline in the Chinook salmon population is in large part due to the decline alewife, their primary food source.  A recent computer modeling study by the University of Michigan suggests that the Lake Huron decline is due to the lakes inability to support Chinook’s salmons main food source.  The alewife’s decline can be traced back to overstocking of Chinook salmon and competition for food from non-native mussel species.  The Lake Michigan Chinook salmon population may suffer the same fate.  Since 2012, the salmon population in Lake Michigan is down 75%.
