well hate to say this but the dollies that ive caught in bc this year they all got pink spots on them. ya bc and alberta might call them differently but end case scenario they all different bull trout species...

Hate to say atoadaso, but worst case Ontario, you are incorrect.
What are different bull trout species? 2 different kinds of bull trout? The point of species designation is that there is only 1. Do you mean they are all different charr? Many charr have pink spots. What makes you think you caught a Dolly and not a Bull?

kitimat river,dollies,salvelinus malma.oval body not dominated by head. with a little species id they can be told apart. if a river makes the west coat within a hundred or so miles your in dolly varden waters. BC contains both in numbers. Alberta has very few dollies stocked.

Ya, for sure, using some knowledge of watersheds, in particular, knowing when a watershed only contains one of the two species can greatly aid in determining your catch.
You will find that many Bull trout do not have large heads, so this character can be very misleading. Using this character one would assume there is a healthy population of large Dollies in the k-lakes, however Dollies are only present in Chester Lake in Alberta.
There is still much to learn about both of these species. In the last 10 years the known range of the bull trout has been expanded to 64N, over 500km further north than was previously known.
