Rick, Probably a different sub species. Up there you would get Thalamus Arcticus. Here we get Thalamus Thalamus. Not a huge difference. Here it extends our fishing through the winter, the trout season extends from March or April to the end of September. Without the grayling it would mean putting the rods away for the winter. Its either grayling or stocked rainbows in ponds through the winter.

Cheers,
A.
