Blackfish/Bergall hybrid?

[bulletbob]

Just wondering if this happens?
I recall a conversation many years ago on the old Skipper-[the 40 footer] between Capt Dom and one of the every week regulars concerning the mottled brown/tan blackfish we see from time to time.. I have caught several that color, but never any real big ones.. If I remember the conversation correctly, these fish were suppossed to be a cross between blackfish and bergalls. Its no big deal and it may be false, but over the years I have wondered about it.
No one knew blackfish better than capt Dom did, and I seem to recall him saying they were capable of cross breeding.. I can't be sure, it was decades ago.. Any one ever hear this???... bob
