|• Due to little natural reproduction and the
resulting dependance on stocking, reductions in rainbow trout were not
evident in Michigan waters of Lake Huron.
|• No evidence of declines in rainbow trout runs
are evident in Main Basin tributaries in Ontario waters.
|• Possibly Michigan planted fish are sustaining
numbers which are therefore not dependent on natural reproduction.
|• Recent marking of rainbow trout by Michigan will soon determine the level
of natural reproduction that is occurring in Ontario rivers on the Main
